    "content": "\n\n## Issue\n\nWelcome to use [issue tracker](https://github.com/alibaba/arthas/issues) to give us :bowtie::\n\n* feedbacks - what you would like to have;\n* usage tips - what usages you have found splendid;\n* experiences - how you use Arthas to do **effective** troubleshooting;\n\n## Documentation\n\n* Under `site/docs/`.\n\n## Online Tutorials\n\nPlease refer to [README.MD at killercoda branch](https://github.com/alibaba/arthas/tree/killercoda/README.md#contribution-guide)\n\n## Developer\n\n* Arthas runtime supports JDK6+\n* It is recommended to use JDK8 to compile, and you will encounter problems when using a higher version. Reference https://github.com/alibaba/arthas/tree/master/.github/workflows\n* If you encounter jfr related problems, it is recommended to use `8u262` and later versions of openjdk8 or zulu jdk8, https://mail.openjdk.org/pipermail/jdk8u-dev/2020-July/012143.html\n### Local Installation\n\n> Note: After modifying `arthas-vmtool` related codes, the packaging results need to be manually copied to the `lib/` path of this repo, and will not be copied automatically.\n\nRecommend to use [`as-package.sh`](as-package.sh) to package, which will auto-install the latest Arthas to local `~/.arthas` and when debugging, Arthas will auto-load the latest version.\n\nTip: for faster local iteration, you can use `./as-package.sh --fast` (skip `clean` and skip documentation front-end build in `site` module). If you need to rebuild docs, run without `--fast` or use `./mvnw clean package -DskipTests -P full`.\n\n* To support jni, cpp compiling environment support is required\n* mac needs to install xcode\n* windows need to install gcc\n\nF.Y.I\n1. when using [`as.sh`](https://github.com/alibaba/arthas/blob/master/bin/as.sh) to start Arthas, it will get the latest version under `~/.arthas/lib`;\n2. when [`as-package.sh`](as-package.sh) packaging, it will get the version from `pom.xml` and suffix it with the current timestamp e.g. `3.0.5.20180917161808`. \n\nYou can also use `./mvnw clean package -DskipTests` to package and generate a `zip` under `packaging/target/` but remember when `as.sh` starts, it load the version under `~/.arthas/lib`.\n\n### Start Arthas in specified version\n\nWhen there are several different version, you can use `--use-version` to specify the version of Arthas to start your debug.\n\n```bash\n./as.sh --use-version 3.0.5.20180919185025\n```\n\nTip: you can use `--versions` to list all available versions.\n\n```bash\n./as.sh --versions\n```\n\n### Debug\n\n* [Debug Arthas In IDEA](https://github.com/alibaba/arthas/issues/222)\n\n### Packaging All\n\n* when packaging the whole project (Packaging All), you need to execute:\n\n    ```bash\n    ./mvnw clean package -DskipTests -P full\n    ```\n\n---\n\n\n\n## Issue\n\n欢迎在issue里对arthas做反馈，分享使用技巧，排查问题的经历。\n\n* https://github.com/alibaba/arthas/issues\n\n## 改进用户文档\n\n用户文档在`site/docs/`目录下，如果希望改进arthas用户文档，欢迎提交PR。\n\n## 改进在线教程\n\n请参考[killercoda 分支下的说明](https://github.com/alibaba/arthas/tree/killercoda/README_CN.md#贡献指南)\n\n## 开发者相关\n\n* Arthas运行支持JDK6+\n* 建议使用JDK8来编译，使用高版本会遇到问题。参考 https://github.com/alibaba/arthas/tree/master/.github/workflows\n* 如果遇到jfr相关问题，建议使用`8u262`及之后的高版本 openjdk8 或者zulu jdk8， https://mail.openjdk.org/pipermail/jdk8u-dev/2020-July/012143.html\n### 安装到本地\n\n> 注意： 修改`arthas-vmtool`相关代码后，打包结果需要手动复制到本仓库的 `lib/` 路径下，不会自动复制。\n\n本地开发时，推荐执行`as-package.sh`来打包，会自动安装最新版本的arthas到`~/.arthas`目录里。debug时会自动使用最新版本。\n\n提示：本地快速迭代可以执行 `./as-package.sh --fast`（跳过 `clean`，并跳过 `site` 模块的文档前端构建）。如果需要重建文档，请不要使用 `--fast`，或者执行 `./mvnw clean package -DskipTests -P full`。\n\n* 代码里要编译jni，需要cpp编译环境支持\n* mac需要安装xcode\n* windows需要安装gcc\n\n\n`as.sh`在启动时，会对`~/.arthas/lib`下面的目录排序，取最新的版本。`as-package.sh`在打包时，会取`pom.xml`里的版本号，再拼接上当前时间，比如： `3.0.5.20180917161808`，这样子排序时取的就是最新的版本。\n\n也可以直接 `./mvnw clean package -DskipTests`打包，生成的zip在 `packaging/target/` 下面。但是注意`as.sh`启动加载的是`~/.arthas/lib`下面的版本。\n\n### 启动指定版本的arthas\n\n本地开发时，可能会产生多个版本，可以用 `--use-version` 参数来指定版本，比如\n\n```bash\n./as.sh --use-version 3.0.5.20180919185025\n```\n\n可以用`--versions`参数来列出所有版本：\n\n```bash\n./as.sh --versions\n```\n\n### Debug\n\n* [Debug Arthas In IDEA](https://github.com/alibaba/arthas/issues/222)\n\n### 全量打包\n\n\n* 全量打包时，需要配置下面的参数：\n\n    ```\n    ./mvnw clean package -DskipTests -P full\n    ```\n\n### Release Steps\n\n发布release版本流程：\n\n* 如果 arthas-vmtool 有更新，则需要手动触发action，构建后会把新的动态库文件提交到 lib 目录。 https://github.com/alibaba/arthas/actions/workflows/build-vmtool.yaml\n* 修改`as.sh`里的版本，最后修改日期， `Bootstrap.java`里的版本，Dockerfile里的版本\n* 修改本地的maven settings.xml\n* 执行一次 gpg --sign /tmp/2.txt ，让 gpg 后台进程启动，否则打包可能失败\n* mvn clean deploy -DskipTests -P full -P release\n\n* 到 https://central.sonatype.com/publishing/deployments ，Publish 自己的 Deployment\n* 发布后，可以到这里查看是否同步到仓库里了： https://repo1.maven.org/maven2/com/taobao/arthas/arthas-packaging/\n* 发布完maven仓库之后，需要到阿里云的仓库里检查是否同步，有可能有延时\n\n    比如下载地址： https://maven.aliyun.com/repository/public/com/taobao/arthas/arthas-packaging/3.x.x/arthas-packaging-3.x.x-bin.zip\n    \n    版本号信息地址： https://maven.aliyun.com/repository/public/com/taobao/arthas/arthas-packaging/maven-metadata.xml\n\n* 打上tag，push tag到仓库上\n* 需要更新 gh-pages 分支下面的 arthas-boot.jar/math-game.jar/as.sh ，下载 doc.zip，解压覆盖掉文档的更新，可以通过 github action 更新： https://github.com/alibaba/arthas/actions/workflows/update-doc.yaml\n* 需要更新docker镜像，push新的tag：https://hub.docker.com/r/hengyunabc/arthas/tags?page=1&ordering=last_updated\n\n    可以通过 github action push： https://github.com/alibaba/arthas/actions/workflows/push-docker.yaml \n\n* 更新README.md，比如增加了新命令，要加上说明，更新wiki的链接\n* 更新release页面的 issue信息，修改信息等\n* 更新 https://arthas.aliyun.com/api/latest_version api\n* 更新内部的版本\n"

If issues are encountered in production systems, it is impossible to use IDEs to debug the application remotely. More importantly, debugging in production environment is unacceptable, as it will suspend all the threads, resulting in the suspension of business services. \n\nDevelopers could always try to reproduce the same issue on the test/staging environment. However, this is tricky as some issues cannot be reproduced easily on a different environment, or even disappear once restarted. \n\nAnd if you're thinking of adding some logs to your code to help troubleshoot the issue, you will have to go through the following lifecycle; test, staging, and then to production. Time is money! This approach is inefficient! Besides, the issue may not be reproducible once the JVM is restarted, as described above.\n\nArthas was built to solve these issues. A developer can troubleshoot your production issues on-the-fly. No JVM restart, no additional code changes. Arthas works as an observer, which will never suspend your existing threads.\n\n### Key features\n\n* Check whether a class is loaded, or where the class is being loaded. (Useful for troubleshooting jar file conflicts)\n* Decompile a class to ensure the code is running as expected.\n* View classloader statistics, e.g. the number of classloaders, the number of classes loaded per classloader, the classloader hierarchy, possible classloader leaks, etc.\n* View the method invocation details, e.g. method parameter, return object, thrown exception, and etc.\n* Check the stack trace of specified method invocation. This is useful when a developers wants to know the caller of the said method.\n* Trace the method invocation to find slow sub-invocations.\n* Monitor method invocation statistics, e.g. qps, rt, success rate and etc.\n* Monitor system metrics, thread states and cpu usage, gc statistics, and etc.\n* Supports command line interactive mode, with auto-complete feature enabled.\n* Supports telnet and websocket, which enables both local and remote diagnostics with command line and browsers.\n* Supports profiler/Flame Graph\n* Support get objects in the heap that are instances of the specified class. \n* Supports JDK 6+ (version 4.x no longer supports JDK 6 and JDK 7).\n* Supports Linux/Mac/Windows.\n\n\n### Online Tutorials(Recommended)\n\n* [View](https://arthas.aliyun.com/doc/arthas-tutorials.html?language=en)\n\n### Quick start\n\n#### Use `arthas-boot`(Recommended)\n\nDownload`arthas-boot.jar`，Start with `java` command:\n\n```bash\ncurl -O https://arthas.aliyun.com/arthas-boot.jar\njava -jar arthas-boot.jar\n```\n\nPrint usage:\n\n```bash\njava -jar arthas-boot.jar -h\n```\n\n#### Use `as.sh`\n\nYou can install Arthas with one single line command on Linux, Unix, and Mac. Copy the following command and paste it into the command line, then press *Enter* to run:\n\n```bash\ncurl -L https://arthas.aliyun.com/install.sh | sh\n```\n\nThe command above will download the bootstrap script `as.sh` to the current directory. You can move it any other place you want, or put its location in `$PATH`.\n\nYou can enter its interactive interface by executing `as.sh`, or execute `as.sh -h` for more help information.\n\n\n###

https://arthas.aliyun.com/doc/en/trace\n\nSee what is slowing down your method invocation with trace command:\n\n![trace](site/docs/.vuepress/public/images/trace.png)\n\n#### Watch\n\n* https://arthas.aliyun.com/doc/en/watch\n\nWatch the first parameter and thrown exception of `test.arthas.TestWatch#doGet` only if it throws exception.\n\n```bash\n$ watch test.arthas.TestWatch doGet {params[0], throwExp} -e\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 65 ms.\nts=2018-09-18 10:26:28;result=@ArrayList[\n

[here](README.md).\n\n`Arthas` 是Alibaba开源的Java诊断工具，深受开发者喜爱。\n\n当你遇到以下类似问题而束手无策时，`Arthas`可以帮助你解决：\n\n0. 这个类从哪个 jar 包加载的？为什么会报各种类相关的 Exception？\n0. 我改的代码为什么没有执行到？难道是我没 commit？分支搞错了？\n0. 遇到问题无法在线上 debug，难道只能通过加日志再重新发布吗？\n0. 线上遇到某个用户的数据处理有问题，但线上同样无法 debug，线下无法重现！\n0. 是否有一个全局视角来查看系统的运行状况？\n0. 有什么办法可以监控到JVM的实时运行状态？\n0. 怎么快速定位应用的热点，生成火焰图？\n0. 怎样直接从JVM内查找某个类的实例？\n\n`Arthas`支持JDK 6+（4.x 版本不再支持 JDK 6 和 JDK 7），支持Linux/Mac/Windows，采用命令行交互模式，同时提供丰富的 `Tab` 自动补全功能，进一步方便进行问题的定位和诊断。\n\n\n### 在线教程(推荐)\n\n* [查看](https://arthas.aliyun.com/doc/arthas-tutorials.html?language=cn)\n\n### 快速开始\n\n#### 使用`arthas-boot`(推荐)\n\n下载`arthas-boot.jar`，然后用`java -jar`的方式启动：\n\n```bash\ncurl -O https://arthas.aliyun.com/arthas-boot.jar\njava -jar arthas-boot.jar\n```\n\n打印帮助信息：\n\n```bash\njava -jar arthas-boot.jar -h\n```\n\n* 如果下载速度比较慢，可以使用aliyun的镜像：`java -jar arthas-boot.jar --repo-mirror aliyun --use-http`\n\n#### 使用`as.sh`\n\nArthas 支持在 Linux/Unix/Mac 等平台上一键安装，请复制以下内容，并粘贴到命令行中，敲 `回车` 执行即可：\n\n```bash\ncurl -L https://arthas.aliyun.com/install.sh | sh\n```\n\n上述命令会下载启动脚本文件 `as.sh` 到当前目录，你可以放在任何地方或将其加入到 `$PATH` 中。\n\n直接在shell下面执行`./as.sh`，就会进入交互界面。\n\n也可以执行`./as.sh -h`来获取更多参数信息。\n\n### 文档\n\n* [在线教程(推荐)](https://arthas.aliyun.com/doc/arthas-tutorials.html?language=cn)\n* [用户文档](https://arthas.aliyun.com/doc/)\n*

判断是否已插入了，可以在两行中间查询，有没有 SpyAPI 的invoke?\n * \n * TODO trace的怎么搞？ trace 只记录一次就可以了 classname|method|desc|trace ? 怎么避免 trace 到\n * SPY的invoke ？直接忽略？\n * \n * TODO trace命令可以动态的增加 新的函数进去不？只要关联上同一个 Listener应该是可以的。\n * \n * TODO 在SPY里放很多的 Object数组，然后动态的设置进去？ 比如有新的 Listener来的时候。 这样子连查表都不用了。 甚至可以动态生成\n * 存放这些 Listener数组的类？ 这样子的话，只要有 Binding那里，查询到一个具体分配好的类， 这样子就可以了？\n * 甚至每个ClassLoader里都动态生成这样子的 存放类，那么这样子不可以避免查 ClassLoader了么？\n * \n * 动态为每一个增强类，生成一个新的类，新的类里，有各种的 ID 数组，保存每一个类的每一种 trace 点的信息？？\n * \n * 多个 watch命令 对同一个类，现在的逻辑是，每个watch都有一个自己的 TransForm，但不会重复增强，因为做了判断。\n * watch命令停止时，也没有去掉增强的代码。 只有reset时 才会去掉。\n * \n * 其实用户想查看局部变量，并不是想查看哪一行！ 而是想看某个函数里子调用时的 局部变量的值！ 所以实际上是想要一个新的命令，比如 watchinmethod\n * ， 可以 在某个子调用里，\n * \n * TODO 现在的trace 可以输出行号，可能不是很精确，但是可以对应上的。 这个在新的方式里怎么支持？ 增加一个 linenumber binding？\n * 从mehtodNode，向上查找到最近的行号？\n * \n * TODO 防止重复增强，最重要的应该还是动态增加 annotation，这个才是真正可以做到某一行，某一个子 invoke 都能识别出来的！ 无论是\n * transform多少次！ 字节码怎么动态加 annotation ？ annotation里签名用 url ?的key/value方式表达！\n * 这样子可以有效还原信息\n * \n * TODO 是否考虑一个 trace /watch命令之后，得到一个具体的 Listener ID， 允许在另外的窗口里，再次\n * trace/watch时指定这个ID，就会查找到，并处理。 这样子的话，真正达到了动态灵活的，一层一层增加的trace ！\n * \n * \n * @author hengyunabc 2020-04-24\n *\n

trace命令可以动态的增加 新的函数进去不？只要关联上同一个 Listener应该是可以的。\n * \n * TODO 在SPY里放很多的 Object数组，然后动态的设置进去？ 比如有新的 Listener来的时候。 这样子连查表都不用了。 甚至可以动态生成\n * 存放这些 Listener数组的类？ 这样子的话，只要有 Binding那里，查询到一个具体分配好的类， 这样子就可以了？\n * 甚至每个ClassLoader里都动态生成这样子的 存放类，那么这样子不可以避免查 ClassLoader了么？\n * \n * 动态为每一个增强类，生成一个新的类，新的类里，有各种的 ID 数组，保存每一个类的每一种 trace 点的信息？？\n * \n * 多个 watch命令 对同一个类，现在的逻辑是，每个watch都有一个自己的 TransForm，但不会重复增强，因为做了判断。\n * watch命令停止时，也没有去掉增强的代码。 只有reset时 才会去掉。\n * \n * 其实用户想查看局部变量，并不是想查看哪一行！ 而是想看某个函数里子调用时的 局部变量的值！ 所以实际上是想要一个新的命令，比如 watchinmethod\n * ， 可以 在某个子调用里，\n * \n * TODO 现在的trace 可以输出行号，可能不是很精确，但是可以对应上的。 这个在新的方式里怎么支持？ 增加一个 linenumber binding？\n * 从mehtodNode，向上查找到最近的行号？\n * \n * TODO 防止重复增强，最重要的应该还是动态增加 annotation，这个才是真正可以做到某一行，某一个子 invoke 都能识别出来的！ 无论是\n * transform多少次！ 字节码怎么动态加 annotation ？ annotation里签名用 url ?的key/value方式表达！\n * 这样子可以有效还原信息\n * \n * TODO 是否考虑一个 trace /watch命令之后，得到一个具体的 Listener ID， 允许在另外的窗口里，再次\n * trace/watch时指定这个ID，就会查找到，并处理。 这样子的话，真正达到了动态灵活的，一层一层增加的trace ！\n * \n * \n * @author hengyunabc 2020-04-24\n *\n */\npublic class AdviceListenerManager {\n    private static final Logger logger =

Worse still, the issue may not be fixed since it might be irreproduceable \nonce the JVM is restarted as above.\n\nArthas is built to solve these issues. A developer can troubleshoot production\nissues on the fly. No JVM restart. no additional code changes. Arthas works as \nan observer, that is, it will never suspend your running threads.\n\n.SH OPTIONS AND ARGUEMENTS\n\n.TP \n.B -h, --help \nprint usage\n\n.TP \n.B --target-ip <value>\nThe target JVM listen ip, the default ip is 127.0.0.1\n\n.TP \n.B --telnet-port <value>\nThe target jvm listen telnet port, default is 3658\n\n.TP \n.B --http-port <value>\nThe target jvm listen http port, default is 8563\n\n.TP\n.B --session-timeout <value> \nThe session timeout time in seconds, default 1800 (30min)\n\n.TP\n.B --arthas-home <value> \nThe arthas home\n\n.TP \n.B --use-version <value>\nUse specific version of arthas\n\n.TP \n.B --repo-mirror <value>\nUse special maven repository mirror, value is center/aliyun or http repo url.\n\n.TP\n.B --versions\nList local and remote arthas versions\n\n.TP \n.B --use-http \nEnforce use http to download, default use https\n\n.TP\n.B --attach-only\nAttach target process only, do not connect\n\n.TP \n.B --debug-attach \nDebug attach agent \n\n.TP \n.B -c, --command <value> \nCommand to execute, multiple commands separated by \";\"\n\n.TP \n.B -f, --batch-file <value>\nThe batch file to execute \n\n.TP \n.B --height <value> \narthas-client terminal height \n\n.TP \n.B --width <value>\narthas-client terminal width \n\n.TP \n.B -v, --verbose \nVerbose, print debug info.\n\n.TP\n.B <pid>\nTarget pid\n\n"

    "content": "# 简介\n\n![](/images/arthas.png)\n\nArthas 是一款线上监控诊断产品，通过全局视角实时查看应用 load、内存、gc、线程的状态信息，并能在不修改应用代码的情况下，对业务问题进行诊断，包括查看方法调用的出入参、异常，监测方法执行耗时，类加载信息等，大大提升线上问题排查效率。\n\n## 背景\n\n通常，本地开发环境无法访问生产环境。如果在生产环境中遇到问题，则无法使用 IDE 远程调试。更糟糕的是，在生产环境中调试是不可接受的，因为它会暂停所有线程，导致服务暂停。\n\n开发人员可以尝试在测试环境或者预发环境中复现生产环境中的问题。但是，某些问题无法在不同的环境中轻松复现，甚至在重新启动后就消失了。\n\n如果您正在考虑在代码中添加一些日志以帮助解决问题，您将必须经历以下阶段：测试、预发，然后生产。这种方法效率低下，更糟糕的是，该问题可能无法解决，因为一旦 JVM 重新启动，它可能无法复现，如上文所述。\n\nArthas 旨在解决这些问题。开发人员可以在线解决生产问题。无需 JVM 重启，无需代码更改。 Arthas 作为观察者永远不会暂停正在运行的线程。\n\n## Arthas（阿尔萨斯）能为你做什么？\n\n`Arthas` 是 Alibaba 开源的 Java 诊断工具，深受开发者喜爱。\n\n当你遇到以下类似问题而束手无策时，`Arthas`可以帮助你解决：\n\n0. 这个类从哪个 jar 包加载的？为什么会报各种类相关的 Exception？\n1. 我改的代码为什么没有执行到？难道是我没 commit？分支搞错了？\n2. 遇到问题无法在线上 debug，难道只能通过加日志再重新发布吗？\n3. 线上遇到某个用户的数据处理有问题，但线上同样无法 debug，线下无法重现！\n4. 是否有一个全局视角来查看系统的运行状况？\n5. 有什么办法可以监控到 JVM 的实时运行状态？\n6. 怎么快速定位应用的热点，生成火焰图？\n7. 怎样直接从 JVM 内查找某个类的实例？\n\n`Arthas` 支持 JDK 6+（4.x 版本不再支持 JDK 6 和 JDK 7），支持 Linux/Mac/Windows，采用命令行交互模式，同时提供丰富的 `Tab` 自动补全功能，进一步方便进行问题的定位和诊断。\n\n**如果您在使用 Arthas，请让我们知道，您的使用对我们非常重要：[查看](https://github.com/alibaba/arthas/issues/111)**\n\n## Contributors\n\n[![](https://opencollective.com/arthas/contributors.svg?width=890&button=false)](https://github.com/alibaba/arthas/graphs/contributors)\n"

中使用了 ognl 这个更加轻量的表达式求值库来代替 groovy，彻底解决了 groovy 引起的 FGC 风险。但由于这个替换，导致原来使用 groovy 脚本编写的自定义脚本失效。这个问题留待后续解决。\n\n在 3.0 中，watch 命令的表达式部分的书写有了一些改变，详见[这里](https://arthas.aliyun.com/doc/watch)\n\n#### 提升 rt 统计精度\n\nArthas 2.0 中，统计 rt 都是以`ms`为单位，对于某些比较小的方法调用，耗时在毫秒以下的都会被认为是 0ms，造成 trace 总时间和各方法的时间相加不一致等问题（虽然这里面确实会有误差，主要 Arthas 自身的开销）。Arthas 3.0 中所有 rt 的单位统一改为使用`ns`来统计，精准捕获你的方法耗时，让 0ms 这样无意义的统计数据不再出现！\n\n```\n$ tt -l\n INDEX     TIMESTAMP               COST(ms)    IS-RET    IS-EXP   OBJECT            CLASS

的时候，经常会出现某个方法间隙性的 rt 飙高，但是我们只想知道 rt 高的时候，是哪里慢了，对于正常 rt 的方法我们并不关心，Arthas 3.0 支持了按`#cost`(方法执行耗时,单位为`ms`)进行过滤，只输出符合条件的 trace 路径，目前，这三个命令的相关文档已经做了更新，增加了该用法的示例。\n\n#### sysprop 命令操作 SystemProperty\n\nsysprop 命令支持查看所有的系统属性，以及针对特定属性进行查看和修改。\n\n```\n$ sysprop\n...\n os.arch                                              x86_64\n java.ext.dirs

命令计算线程 cpu 占用的逻辑，默认是采样 100ms 内各个线程的 cpu 使用情况并计算 cpu 消耗占比。有时候 100ms 的时间间隔太短，看不出问题所在，Arthas3.0 中 thread 命令支持设置采样间隔(以`ms`为单位)，可以观察任意时间段内的 cpu 消耗占比情况。\n\n```\n$ thread -i 1000\nThreads Total: 74, NEW: 0,

    "content": "# Arthas 后台异步任务\n\n[`后台异步任务`在线教程](https://arthas.aliyun.com/doc/arthas-tutorials?language=cn&id=case-async-jobs)\n\narthas 中的后台异步任务，使用了仿 linux 系统任务相关的命令。[linux 任务相关介绍](https://ehlxr.me/2017/01/18/Linux-%E4%B8%AD-fg%E3%80%81bg%E3%80%81jobs%E3%80%81-%E6%8C%87%E4%BB%A4/)。\n\n## 1. 使用&在后台执行任务\n\n比如希望执行后台执行 trace 命令，那么调用下面命令\n\n```bash\ntrace Test t &\n```\n\n这时命令在后台执行，可以在 console 中继续执行其他命令。\n\n## 2. 通过 jobs 查看任务\n\n如果希望查看当前有哪些 arthas 任务在执行，可以执行 jobs 命令，执行结果如下\n\n```bash\n$ jobs\n[10]*\n       Stopped           watch com.taobao.container.Test test \"params[0].{? #this.name == null }\" -x 2\n       execution count : 19\n       start time      : Fri Sep 22 09:59:55 CST 2017\n       timeout date    : Sat Sep 23 09:59:55 CST 2017\n       session         : 3648e874-5e69-473f-9eed-7f89660b079b (current)\n```\n\n可以看到目前有一个后台任务在执行。\n\n- job id 是 10, `*` 表示此 job 是当前 session 创建\n- 状态是 Stopped\n- execution count 是执行次数，从启动开始已经执行了 19 次\n- timeout date 是超时的时间，到这个时间，任务将会自动超时退出\n\n## 3. 任务暂停和取消\n\n当任务正在前台执行，比如直接调用命令`trace Test t`或者调用后台执行命令`trace Test t &`后又通过`fg`命令将任务转到前台。这时 console 中无法继续执行命令，但是可以接收并处理以下事件：\n\n- ‘ctrl + z’：将任务暂停。通过`jobs`查看任务状态将会变为 Stopped，通过`bg <job-id>`或者`fg <job-id>`可让任务重新开始执行\n- ‘ctrl + c’：停止任务\n- ‘ctrl + d’：按照 linux 语义应当是退出终端，目前 arthas 中是空实现，不处理\n\n## 4. fg、bg 命令，将命令转到前台、后台继续执行\n\n- 任务在后台执行或者暂停状态（`ctrl + z`暂停任务）时，执行`fg <job-id>`将可以把对应的任务转到前台继续执行。在前台执行时，无法在 console 中执行其他命令\n- 当任务处于暂停状态时（`ctrl + z`暂停任务），执行`bg <job-id>`将可以把对应的任务在后台继续执行\n- 非当前 session 创建的 job，只能由当前 session fg 到前台执行\n\n## 5. 任务输出重定向\n\n可通过`>`或者`>>`将任务输出结果输出到指定的文件中，可以和`&`一起使用，实现 arthas 命令的后台异步任务。比如：\n\n```bash\n$ trace Test t >> test.out &\n```\n\n这时 trace 命令会在后台执行，并且把结果输出到应用`工作目录`下面的`test.out`文件。可继续执行其他命令。并可查看文件中的命令执行结果。可以执行`pwd`命令查看当前应用的`工作目录`。\n\n```bash\n$ cat test.out\n```\n\n如果没有指定重定向文件，则会把结果输出到`~/logs/arthas-cache/`目录下，比如：\n\n```bash\n$ trace Test t >>  &\njob id  : 2\ncache location  : /Users/admin/logs/arthas-cache/28198/2\n```\n\n此时命令会在后台异步执行，并将结果异步保存在文件（`~/logs/arthas-cache/${PID}/${JobId}`）中；\n\n- 此时任务的执行不受 session 断开的影响；任务默认超时时间是 1 天，可以通过全局 `options` 命令修改默认超时时间；\n- 此命令的结果将异步输出到 \b 文件中；此时不管 `save-result` 是否为 true，都不会再往`~/logs/arthas-cache/result.log` 中异步写结果。\n\n## 6. 停止命令\n\n异步执行的命令，如果希望停止，可执行`kill <job-id>`\n\n## 7. 其他\n\n- 最多同时支持 8 个命令使用重定向将结果写日志\n- 请勿同时开启过多的后台异步命令，以免对目标 JVM 性能造成影响\n- 如果不想停止 arthas，继续执行后台任务，可以执行 `quit` 退出 arthas 控制台（`stop` 会停止 arthas 服务）\n"

ClassLoader 的 class name |\n|             `[c: r:]` | 用 ClassLoader 去查找 resource             |\n|          `[c: load:]` | 用 ClassLoader 去加载指定的类              |\n\n### `--url-classes` 参数说明\n\n|          参数名称 | 参数说明                                                                  |\n| ----------------: | :------------------------------------------------------------------------ |\n|   `--url-classes` | 统计指定 ClassLoader 中，已加载类与 `codeSource(URL/jar)` 的关系          |\n|   `-d, --details` | 详情模式：列出每个 URL/jar 加载的类名（建议配合 `-n/--limit` 控制输出量） |\n|      `--jar <kw>` | 按 jar 包名/URL 关键字过滤（默认包含匹配）                                |\n|    `--class <kw>` | 按类名/包名关键字过滤（默认包含匹配）                                     |\n|     `-E, --regex` | `--jar/--class` 使用正则匹配（默认关键字包含匹配）                        |\n| `-n, --limit <N>` | 详情模式下，每个 URL/jar 最多展示 N 个类（100 默认）                      |\n\n## 使用参考\n\n### 按类加载类型查看统计信息\n\n```bash\n$ classloader\n name                                       numberOfInstances  loadedCountTotal\n com.taobao.arthas.agent.ArthasClassloader  1                  2115\n BootstrapClassLoader                       1                  1861\n sun.reflect.DelegatingClassLoader

按类加载实例查看统计信息\n\n```bash\n$ classloader -l\n name                                                loadedCount  hash      parent\n BootstrapClassLoader                                1861         null

的继承树\n\n```bash\n$ classloader -t\n+-BootstrapClassLoader\n+-sun.misc.Launcher$ExtClassLoader@66350f69\n  +-com.taobao.arthas.agent.ArthasClassloader@68b31f0a\n  +-sun.misc.Launcher$AppClassLoader@3d4eac69\nAffect(row-cnt:4) cost in 3 ms.\n```\n\n### 查看 URLClassLoader 实际的 urls\n\n```bash\n$ classloader -c

ClassLoader 的 hashcode。\n\n对于只有唯一实例的 ClassLoader 可以通过 class name 指定，使用起来更加方便：\n\n```bash\n$ classloader --classLoaderClass sun.misc.Launcher$AppClassLoader\nfile:/private/tmp/math-game.jar\nfile:/Users/hengyunabc/.arthas/lib/3.0.5/arthas/arthas-agent.jar\n\nAffect(row-cnt:9) cost in 3 ms.\n```\n\n### 使用 ClassLoader 去查找 resource\n\n```bash\n$ classloader -c 3d4eac69  -r META-INF/MANIFEST.MF\n jar:file:/System/Library/Java/Extensions/MRJToolkit.jar!/META-INF/MANIFEST.MF\n jar:file:/private/tmp/math-game.jar!/META-INF/MANIFEST.MF\n jar:file:/Users/hengyunabc/.arthas/lib/3.0.5/arthas/arthas-agent.jar!/META-INF/MANIFEST.MF\n```\n\n也可以尝试查找类的 class 文件：\n\n```bash\n$ classloader -c 1b6d3586 -r java/lang/String.class\n jar:file:/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/lib/rt.jar!/java/lang/String.class\n```\n\n### 使用 ClassLoader 去加载类\n\n```bash\n$ classloader -c 3d4eac69 --load demo.MathGame\nload class success.\n class-info        demo.MathGame\n code-source       /private/tmp/math-game.jar\n name

warning\n注意，基于 JVM 目前已加载的所有类统计，不代表`Unused URLs`可以从应用中删掉。因为可能将来需要从`Unused URLs`里加载类，或者需要加载`resources`。\n:::\n\n```\n$ classloader --url-stat\n com.taobao.arthas.agent.ArthasClassloader@3c41660,

file:/tmp/jdk1.8/Contents/Home/jre/lib/ext/zipfs.jar\n```\n\n### 查看指定 ClassLoader 的类与 jar(URL) 的关系列表\n\n`--url-classes` 用于统计指定 ClassLoader 中，类来自哪个 jar(URL)，以及每个 jar(URL) 加载了多少类。\n\n```bash\n$ classloader -c 3d4eac69 --url-classes\nsun.misc.Launcher$AppClassLoader@3d4eac69, hash:3d4eac69\n url                                            loadedClassCount\n file:/private/tmp/math-game.jar                 42\n file:/Users/hengyunabc/.arthas/lib/arthas-agent.jar  15\nAffect(row-cnt:2) cost in 3 ms.\n```\n\n按 jar 包名关键字过滤并查看详情（列出类名）：\n\n```bash\n$ classloader -c 3d4eac69 --url-classes -d --jar math-game\n```\n\n进一步按包名/关键字过滤（同时会输出 `matchedClassCount` 便于统计）：\n\n```bash\n$ classloader -c 3d4eac69 --url-classes --jar spring-core --class org.springframework\n```\n"

    "content": "# Docker\n\n## 在 Docker 里使用 JDK\n\n很多时候，应用在 docker 里出现 arthas 无法工作的问题，是因为应用没有安装 JDK ，而是安装了 JRE 。如果只安装了 JRE，则会缺少很多 JAVA 的命令行工具和类库，Arthas 也没办法正常工作。下面介绍两种常见的在 Docker 里使用 JDK 的方式。\n\n### 使用公开的 JDK 镜像\n\n- https://hub.docker.com/_/openjdk/\n\n比如：\n\n```\nFROM openjdk:8-jdk\n```\n\n或者：\n\n```\nFROM openjdk:8-jdk-alpine\n```\n\n### 通过包管理软件来安装\n\n比如：\n\n```bash\n# Install OpenJDK-8\nRUN apt-get update && \\\n    apt-get install -y openjdk-8-jdk && \\\n    apt-get install -y ant && \\\n    apt-get clean;\n\n# Fix certificate issues\nRUN apt-get update && \\\n    apt-get install ca-certificates-java && \\\n    apt-get clean && \\\n    update-ca-certificates -f;\n\n# Setup JAVA_HOME -- useful for docker commandline\nENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/\nRUN export JAVA_HOME\n```\n\n或者：\n\n```bash\nRUN yum install -y \\\n   java-1.8.0-openjdk \\\n   java-1.8.0-openjdk-devel\n\nENV JAVA_HOME /usr/lib/jvm/java-1.8.0-openjdk/\nRUN export JAVA_HOME\n```\n\n## 通过 Docker 快速入门\n\n1. 删除本地已有的`math-game` docker container（非必要）\n\n   ```sh\n   $ docker stop math-game || true && docker rm math-game || true\n   ```\n\n1. 启动`math-game`\n\n   ```sh\n   $ docker run --name math-game -it hengyunabc/arthas:latest /bin/sh -c \"java -jar /opt/arthas/math-game.jar\"\n   ```\n\n1. 启动`arthas-boot`来进行诊断\n\n   ```sh\n   $ docker exec -it math-game /bin/sh -c \"java -jar /opt/arthas/arthas-boot.jar\"\n   * [1]: 9 jar\n\n   [INFO] arthas home: /opt/arthas\n   [INFO] Try to attach process 9\n   [INFO] Attach process 9 success.\n   [INFO] arthas-client connect 127.0.0.1 3658\n   ,---.  ,------. ,--------.,--.  ,--.  ,---.   ,---.\n   /  O  \\ |  .--.

    "content": "# Http API\n\n[`Http API`在线教程](https://arthas.aliyun.com/doc/arthas-tutorials.html?language=cn&id=case-http-api)\n\n## 概览\n\nHttp API\n提供类似 RESTful 的交互接口，请求和响应均为 JSON 格式的数据。相对于 Telnet/WebConsole 的输出非结构化文本数据，Http\nAPI 可以提供结构化的数据，支持更复杂的交互功能，比如特定应用场景的一系列诊断操作。\n\n### 访问地址\n\nHttp API 接口地址为：`http://ip:port/api`，必须使用 POST 方式提交请求参数。如 POST\n`http://127.0.0.1:8563/api` 。\n\n注意：telnet 服务的 3658 端口与 Chrome 浏览器有兼容性问题，建议使用 http 端口 8563 来访问 http 接口。\n\n### 请求数据格式\n\n```json\n{\n  \"action\": \"exec\",\n  \"requestId\": \"req112\",\n  \"sessionId\": \"94766d3c-8b39-42d3-8596-98aee3ccbefb\",\n  \"consumerId\": \"955dbd1325334a84972b0f3ac19de4f7_2\",\n  \"command\": \"version\",\n  \"execTimeout\": \"10000\"\n}\n```\n\n请求数据格式说明：\n\n- `action` : 请求的动作/行为，可选值请参考\"请求 Action\"小节。\n- `requestId` : 可选请求 ID，由客户端生成。\n- `sessionId` : Arthas 会话 ID，一次性命令不需要设置会话 ID。\n- `consumerId` : Arthas 消费者 ID，用于多人共享会话。\n- `command` : Arthas command line 。\n- `execTimeout` : 命令同步执行的超时时间(ms)，默认为 30000。\n\n注意: 不同的 action 使用到参数不同，根据具体的 action 来设置参数。\n\n### 请求 Action\n\n目前支持的请求 Action 如下：\n\n- `exec` : 同步执行命令，命令正常结束或者超时后中断命令执行后返回命令的执行结果。\n- `async_exec` : 异步执行命令，立即返回命令的调度结果，命令执行结果通过`pull_results`获取。\n- `interrupt_job` : 中断会话当前的命令，类似 Telnet `Ctrl + c`的功能。\n- `pull_results` : 获取异步执行的命令的结果，以 http 长轮询（long-polling）方式重复执行\n- `init_session` : 创建会话\n- `join_session` : 加入会话，用于支持多人共享同一个 Arthas 会话\n- `close_session` : 关闭会话\n\n### 响应状态\n\n响应中的 state 属性表示请求处理状态，取值如下：\n\n- `SCHEDULED`：异步执行命令时表示已经创建 job 并已提交到命令执行队列，命令可能还没开始执行或者执行中；\n- `SUCCEEDED`：请求处理成功（完成状态）；\n- `FAILED`：请求处理失败（完成状态），通常附带 message 说明原因；\n- `REFUSED`：请求被拒绝（完成状态），通常附带 message 说明原因；\n\n## 一次性命令\n\n与执行批处理命令类似，一次性命令以同步方式执行。不需要创建会话，不需要设置`sessionId`选项。\n\n```json\n{\n  \"action\": \"exec\",\n  \"command\": \"<Arthas command line>\"\n}\n```\n\n比如获取 Arthas 版本号：\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"exec\",\n  \"command\":\"version\"\n}\n'\n```\n\n响应内容如下：\n\n```json\n{\n  \"state\": \"SUCCEEDED\",\n  \"sessionId\": \"ee3bc004-4586-43de-bac0-b69d6db7a869\",\n  \"body\": {\n    \"results\": [\n      {\n        \"type\": \"version\",\n        \"version\": \"3.3.7\",\n        \"jobId\": 5\n      },\n      {\n        \"jobId\": 5,\n        \"statusCode\": 0,\n        \"type\": \"status\"\n      }\n    ],\n    \"timeExpired\": false,\n    \"command\": \"version\",\n    \"jobStatus\": \"TERMINATED\",\n    \"jobId\": 5\n  }\n}\n```\n\n响应数据解析：\n\n- `state`: 请求处理状态，参考“接口响应状态”说明\n- `sessionId `: Arthas 会话 ID，一次性命令自动创建及销毁临时会话\n- `body.jobId`: 命令的任务 ID，同一任务输出的所有 Result 都是相同的 jobId\n- `body.jobStatus`: 任务状态，同步执行正常结束为`TERMINATED `\n- `body.timeExpired`: 任务执行是否超时\n- `body/results`: 命令执行的结果列表\n\n**命令结果格式说明**\n\n```json\n[\n  {\n    \"type\": \"version\",\n    \"version\": \"3.3.7\",\n    \"jobId\": 5\n  },\n  {\n    \"jobId\": 5,\n    \"statusCode\": 0,\n    \"type\": \"status\"\n  }\n]\n```\n\n- `type` : 命令结果类型，除了`status`等特殊的几个外，其它的保持与 Arthas 命令名称一致。请参考\"[特殊命令结果](#special_command_results)\"小节。\n- `jobId` : 处理命令的任务 ID。\n- 其它字段为每个不同命令的数据。\n\n注意：也可以使用一次性命令的方式执行 watch/trace 等连续输出的命令，但不能中断命令执行，可能出现长时间没有结束的问题。请参考\"[watch 命令输出 map 对象](#change_watch_value_to_map)\"小节的示例。\n\n请尽量按照以下方式处理：\n\n- 设置合理的`execTimeout`，到达超时时间后强制中断命令执行，避免长时间挂起。\n- 通过`-n`参数指定较少的执行次数。\n- 保证命令匹配的方法可以成功命中和 condition-express 编写正确，如果 watch/trace 没有命中就算指定`-n 1`也会挂起等待到执行超时。\n\n## 会话交互\n\n由用户创建及管理 Arthas 会话，适用于复杂的交互过程。访问流程如下：\n\n- 创建会话\n- 加入会话(可选）\n- 拉取命令结果\n- 执行一系列命令\n- 中断命令执行\n- 关闭会话\n\n### 创建会话\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"init_session\"\n}\n'\n```\n\n响应结果：\n\n```json\n{\n  \"sessionId\": \"b09f1353-202c-407b-af24-701b744f971e\",\n  \"consumerId\": \"5ae4e5fbab8b4e529ac404f260d4e2d1_1\",\n  \"state\": \"SUCCEEDED\"\n}\n```\n\n当前会话 ID 为： `b09f1353-202c-407b-af24-701b744f971e`， 当前消费者 ID 为：`5ae4e5fbab8b4e529ac404f260d4e2d1_1 `。\n\n### 加入会话\n\n指定要加入的会话 ID，服务端将分配一个新的消费者 ID。多个消费者可以接收到同一个会话的命令结果。本接口用于支持多人共享同一个会话或刷新页面后重新拉取会话历史记录。\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d

Http long-polling 方式，定时循环拉取结果消息。\n消费者的超时时间为 5 分钟，超时后需要调用`join_session`分配新的消费者。每个消费者单独分配一个缓存队列，按顺序拉取命令结果，不会影响到其它消费者。\n\n请求参数需要指定会话 ID 及消费者 ID:\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"pull_results\",\n  \"sessionId\" : \"b09f1353-202c-407b-af24-701b744f971e\",\n  \"consumerId\" : \"8f7f6ad7bc2d4cb5aa57a530927a95cc_2\"\n}\n'\n```\n\n用 Bash 脚本定时拉取结果消息:\n\n```bash\nwhile true; do curl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"pull_results\",\n  \"sessionId\" : \"2b085b5d-883b-4914-ab35-b2c5c1d5aa2a\",\n  \"consumerId\" : \"8ecb9cb7c7804d5d92e258b23d5245cc_1\"\n}\n' | json_pp; sleep 2; done\n```\n\n注： `json_pp` 工具将输出内容格式化为 pretty json。\n\n响应内容如下：\n\n```json\n{\n  \"body\": {\n    \"results\": [\n      {\n

watch-experss 的值，上面命令中为`{params, returnObj, throwExp}`，所以 watch 结果的 value 为一个长度为 3 的数组，每个元素分别对应相应顺序的表达式。\n请参考\"[watch 命令输出 map 对象](#change_watch_value_to_map)\"小节。\n\n### 中断命令执行\n\n中断会话正在运行的前台 Job（前台任务）：\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d '''\n{\n  \"action\":\"interrupt_job\",\n  \"sessionId\" : \"2b085b5d-883b-4914-ab35-b2c5c1d5aa2a\"\n}\n'''\n```\n\n```\n{\n   \"state\" : \"SUCCEEDED\",\n   \"body\" : {\n      \"jobStatus\" : \"TERMINATED\",\n      \"jobId\" : 3\n   }\n}\n```\n\n### 关闭会话\n\n指定会话 ID，关闭会话。\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d '''\n{\n  \"action\":\"close_session\",\n  \"sessionId\" : \"2b085b5d-883b-4914-ab35-b2c5c1d5aa2a\"\n}\n'''\n```\n\n```json\n{\n  \"state\": \"SUCCEEDED\"\n}\n```\n\n## 鉴权\n\n参考： [auth](auth.md)\n\n## Web UI\n\n![](/images/arthas-web-ui.png \"arthas web ui\")\n\n一个基于 Http API 接口实现的 Web UI，访问地址为： [http://127.0.0.1:8563/ui](http://127.0.0.1:8563/ui) 。\n\n已实现功能：\n\n- 创建会话\n- 复制并打开 url 加入会话，多人共享会话\n- 周期性拉取会话命令结果消息\n- 刷新页面或者加入会话拉取会话历史命令消息\n- 输入命令/中断命令状态控制\n\n待开发功能：\n\n- 改进将命令结果消息可读性\n- 命令输入支持自动完成及命令模板\n- 提供命令帮助\n- 支持个人选项设置\n\n<a id=\"special_command_results\"></a>\n\n## 特殊命令结果\n\n### status\n\n```json\n{\n  \"jobId\": 5,\n  \"statusCode\": 0,\n  \"type\": \"status\"\n}\n```\n\n`type`为`status`表示命令执行状态：\n\n每个命令执行结束后都有唯一一个 status 结果。`statusCode`\n为 0 表示执行成功，`statusCode` 为非 0 值表示执行失败，类似进程退出码(exit code)。\n\n命令执行失败时一般会提供错误消息，如：\n\n```json\n{\n  \"jobId\": 3,\n  \"message\": \"The argument 'class-pattern' is required\",\n  \"statusCode\": -10,\n  \"type\": \"status\"\n}\n```\n\n### input_status\n\n```json\n{\n  \"inputStatus\": \"ALLOW_INPUT\",\n  \"type\": \"input_status\",\n  \"jobId\": 0\n}\n```\n\n`type`为`input_status`表示输入状态：\n\n用于 UI 交互时控制用户输入，每次执行命令前后会发送改变的消息。\n`inputStatus` 的值说明：\n\n- `ALLOW_INPUT` :\n  允许用户输入命令，表示会话没有在执行的前台命令，可以接受新的命令。\n- `ALLOW_INTERRUPT` :\n  允许用户中断命令执行，表示当前正在执行命令，用户可以发送`interrupt_job`中断执行。\n- `DISABLED` : 禁用状态，不能输入命令也不能中断命令。\n\n### command\n\n```json\n{\n  \"type\": \"command\",\n  \"jobId\": 3,\n  \"state\": \"SCHEDULED\",\n  \"command\": \"watch demo.MathGame primeFactors \\\"{params, returnObj, throwExp}\\\" \"\n}\n```\n\n`type` 为`command`表示输入的命令数据：\n\n用于交互 UI 回显用户输入的命令，拉取的会话命令消息历史会包含`command`类型的消息，按顺序处理即可。\n\n### enhancer\n\n```json\n{\n  \"success\": true,\n  \"jobId\": 3,\n  \"effect\": {\n    \"listenerId\": 3,\n    \"cost\": 24,\n    \"classCount\": 1,\n    \"methodCount\": 1\n  },\n  \"type\": \"enhancer\"\n}\n```\n\n`type`为`enhancer`表示类增强结果：\n\n`trace/watch/jad/tt`等命令需要对类进行增强，会接收到这个`enhancer`结果。可能出现`enhancer`结果成功，但没有命中方法的情况，客户端可以根据`enhancer`结果提示用户。\n\n## 案例\n\n### 获取 Java 应用的 Classpath\n\n通过 Http api 查询 Java 应用的 System properties，提取`java.class.path`的值。\n\n```bash\njson_data=$(curl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"exec\",\n  \"command\":\"sysprop\"\n}')\n```\n\n- 使用`sed`提取值：\n\n```bash\nclass_path=$(echo $json_data | tr -d '\\n' | sed 's/.*\"java.class.path\":\"\\([^\"]*\\).*/\\1/')\necho \"classpath: $class_path\"\n```\n\n- 使用`json_pp/awk`提取值\n\n```bash\nclass_path=$(echo $json_data | tr -d '\\n' | json_pp | grep java.class.path | awk -F'\"' '{ print $4 }')\necho \"classpath: $class_path\"\n```\n\n输出内容：\n\n```\nclasspath: demo-arthas-spring-boot.jar\n```\n\n注意：\n\n- `echo $json_data | tr -d '\\n'` : 删除换行符(`line.separator`的值)，避免影响`sed`/`json_pp`命令处理。\n- `awk -F'\"' '{ print $4 }'` : 使用双引号作为分隔符号\n\n<a id=\"change_watch_value_to_map\"></a>\n\n### watch 命令输出 map 对象\n\nwatch 的结果值由计算`watch-express` ognl 表达式产生，可以通过改变 ognl 表达式来生成想要的值，请参考[OGNL 文档](https://commons.apache.org/dormant/commons-ognl/language-guide.html)。\n\n::: tip\nMaps can also be created using a special syntax.\n\n#{ \"foo\" : \"foo value\", \"bar\" : \"bar value\" }\n\nThis creates a Map initialized with mappings for \"foo\" and \"bar\".\n:::\n\n下面的命令生成 map 格式的值：\n\n```bash\nwatch *MathGame prime* '#{ \"params\" : params, \"returnObj\" : returnObj, \"throwExp\": throwExp}' -x 2 -n 5\n```\n\n在 Telnet shell/WebConsole 中执行上面的命令，输出的结果：\n\n```bash\nts=2020-08-06 16:57:20; [cost=0.241735ms] result=@LinkedHashMap[\n    @String[params]:@Object[][\n        @Integer[1],\n    ],\n    @String[returnObj]:@ArrayList[\n        @Integer[2],\n        @Integer[241],\n        @Integer[379],\n    ],\n    @String[throwExp]:null,\n]\n```\n\n用 Http api 执行上面的命令，注意对 JSON 双引号转义：\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d @- << EOF\n{\n  \"action\":\"exec\",\n  \"execTimeout\": 30000,\n  \"command\":\"watch *MathGame prime* '#{ \\\"params\\\" : params, \\\"returnObj\\\" : returnObj, \\\"throwExp\\\": throwExp}' -n 3 \"\n}\nEOF\n```\n\nHttp api 执行结果：\n\n```json\n{\n    \"body\": {\n         ...\n        \"results\": [\n            ...\n

  \"returnObj\": [\n                        2,\n                        5,\n                        17,\n                        23,\n                        23\n                    ]\n                }\n            },\n            {\n                ...\n                \"type\": \"watch\",\n                \"value\": {\n                    \"params\": [\n                        -98278\n                    ],\n                    \"throwExp\": {\n                        \"@type\": \"java.lang.IllegalArgumentException\",\n                        \"localizedMessage\": \"number is: -98278, need >=

}\n                }\n            },\n            ...\n}\n```\n\n可以看到 watch 结果的 value 变成 map 对象，程序可以通过 key 读取结果。\n"

是`RollingFileAppender`，它的 file 是`app.log`\n- `ASYNC`它的`appenderRef`是`APPLICATION`，即异步输出到文件里\n\n### 查看指定名字的 logger 信息\n\n```bash\n[arthas@2062]$ logger -n org.springframework.web\n name                                   org.springframework.web\n class                                  ch.qos.logback.classic.Logger\n classLoader                            sun.misc.Launcher$AppClassLoader@2a139a55\n

ClassLoader 信息，提取对应 ClassLoader 的 hashcode。\n\n如果你使用`-c`，你需要手动输入 hashcode：`-c <hashcode>`\n\n```bash\n[arthas@2062]$ logger -c 2a139a55\n name                                   ROOT\n class

file:/Users/hengyunabc/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar\n appenders                              name            CONSOLE\n                                        class           ch.qos.logback.core.ConsoleAppender\n                                        classLoader     sun.misc.Launcher$AppClassLoader@2a139a55\n                                        classLoaderHash 2a139a55\n                                        target          System.out\n                                        name            APPLICATION\n                                        class           ch.qos.logback.core.rolling.RollingFileAppender\n                                        classLoader     sun.misc.Launcher$AppClassLoader@2a139a55\n                                        classLoaderHash 2a139a55\n                                        file            app.log\n                                        name            ASYNC\n                                        class           ch.qos.logback.classic.AsyncAppender\n                                        classLoader     sun.misc.Launcher$AppClassLoader@2a139a55\n                                        classLoaderHash 2a139a55\n                                        appenderRef     [APPLICATION]\n```\n\n对于只有唯一实例的 ClassLoader 可以通过`--classLoaderClass`指定 class name，使用起来更加方便：\n\n`logger --classLoaderClass sun.misc.Launcher$AppClassLoader`\n\n- 注: 这里 classLoaderClass 在 java 8 是 sun.misc.Launcher$AppClassLoader，而java 11的classloader是jdk.internal.loader.ClassLoaders$AppClassLoader。\n\n`--classLoaderClass` 的值是 ClassLoader 的类名，只有匹配到唯一的 ClassLoader 实例时才能工作，目的是方便输入通用命令，而`-c <hashcode>`是动态变化的。\n\n### 更新 logger level\n\n```bash\n[arthas@2062]$ logger --name ROOT --level debug\nupdate logger level success.\n```\n\n### 指定 classloader 更新 logger level\n\n默认情况下，logger 命令会在 SystemClassloader 下执行，如果应用是传统的`war`应用，或者 spring boot fat jar 启动的应用，那么需要指定 classloader。\n\n可以先用 `sc -d yourClassName` 来查看具体的 classloader hashcode，然后在更新 level 时指定 classloader：\n\n```bash\n[arthas@2062]$ logger -c 2a139a55 --name ROOT --level debug\n```\n\n### 查看没有 appender 的 logger 的信息\n\n默认情况下，`logger`命令只打印有 appender 的 logger 的信息。如果想查看没有`appender`的 logger 的信息，可以加上参数`--include-no-appender`。\n\n注意，通常输出结果会很长。\n\n```bash\n[arthas@2062]$ logger --include-no-appender\n name                                   ROOT\n class                                  ch.qos.logback.classic.Logger\n classLoader

Context Protocol) configuration\narthas.mcpEndpoint=/mcp\n```\n\n### 2. 启动应用\n\n正常启动 Arthas 或带有 Arthas 的 Java 应用。默认情况下，MCP 服务会在 HTTP 端口 8563 上暴露。\n\n验证 MCP 服务是否启动：\n\n```bash\ncurl http://localhost:8563/mcp\n```\n\n如果返回 MCP 协议信息，说明服务已成功启动。\n\n### 3. 配置 AI 客户端\n\n以下是几种主流 AI 客户端的配置方式：\n\n#### Cherry Studio / Cline\n\n在设置中添加 MCP 服务器配置：\n\n```json\n{\n  \"mcpServers\": {\n    \"arthas-mcp\": {\n      \"type\": \"streamableHttp\",\n      \"url\": \"http://localhost:8563/mcp\"\n    }\n  }\n}\n```\n\n## 配置说明\n\n### Arthas 配置项\n\n| 配置项               | 说明                                                         | 默认值             |\n| -------------------- | ------------------------------------------------------------ | ------------------ |\n| `arthas.mcpEndpoint` | MCP 服务的访问路径                                           | 无（需要手动配置） |\n| `arthas.mcpProtocol` | 传输协议模式：`STREAMABLE`（有状态）或 `STATELESS`（无状态） | `STREAMABLE`       |\n| `arthas.httpPort`    | HTTP 服务端口                                                | 8563               |\n| `arthas.password`    | 认证密码（开启认证时使用）                                   | 无                 |\n\n### 传输协议模式\n\nArthas MCP Server 支持两种传输协议模式：\n\n- **STREAMABLE 模式**（默认）：有状态模式，通过 HTTP/SSE 维持持久连接，支持长时间运行的命令（如 watch、trace、monitor 等流式工具）、进度通知和会话状态。适合交互式诊断场景。\n- **STATELESS 模式**：无状态模式，每个请求相互独立，适合简单的一次性查询场景。\n\n在 `arthas.properties` 中配置：\n\n```properties\narthas.mcpEndpoint=/mcp\n# 可选，默认为 STREAMABLE\narthas.mcpProtocol=STREAMABLE\n```\n\n### 认证配置\n\n当在配置文件中设置了 `arthas.password` 时，MCP Server 会自动开启鉴权功能。此时需要在 AI 客户端配置中添加认证头，携带的 Bearer Token 就是配置的密码值。\n\n配置文件示例（`arthas.properties`）：\n\n```properties\narthas.password=your-secure-password\n```\n\nAI 客户端配置示例：\n\n```json\n{\n  \"mcpServers\": {\n    \"arthas-mcp\": {\n      \"type\": \"streamableHttp\",\n      \"url\": \"http://localhost:8563/mcp\",\n      \"headers\": {\n        \"Authorization\": \"Bearer your-secure-password\"\n      }\n    }\n  }\n}\n```\n\n::: warning\n**注意**：Authorization header 中的 token 必须与 `arthas.password` 配置的值完全一致。\n:::\n\n### viewfile 工具目录白名单配置\n\n`viewfile` 工具默认只允许查看以下目录中的文件：\n\n- 当前工作目录下的 `arthas-output` 目录（若存在）\n- 用户 Home 目录下的 `~/logs/` 目录（若存在）\n\n可通过环境变量扩展允许目录：\n\n```bash\nexport ARTHAS_MCP_VIEWFILE_ALLOWED_DIRS=/path/to/dir1,/path/to/dir2\n```\n\n## 反馈与贡献\n\n::: tip\nArthas MCP Server 是实验性功能，欢迎提供反馈和建议！\n:::\n\n-

Want to set object properties, execute `options strict false`, visit /Users/admin/logs/arthas/arthas.log for more details.\n```\n\n用户如果确定要在`ognl`表达式里更新对象，可以执行`options strict false`，关闭`strict`模式。\n\n- 更多信息参考： https://github.com/alibaba/arthas/issues/2128\n"

tip\n使用[async-profiler](https://github.com/jvm-profiling-tools/async-profiler)生成火焰图\n:::\n\n`profiler` 命令支持生成应用热点的火焰图。本质上是通过不断的采样，然后把收集到的采样结果生成火焰图。\n\n`profiler` 命令基本运行结构是 `profiler action [actionArg]`\n\n`profiler` 命令的格式基本与上游项目 [async-profiler](https://github.com/async-profiler/async-profiler) 保持一致，详细的使用方式可参考上游项目的 README、Github Disscussions 以及其他文档资料。\n\n## 参数说明\n\n|    参数名称 | 参数说明                                                        |\n| ----------: | :-------------------------------------------------------------- |\n|    _action_ | 要执行的操作

profiler start\nStarted [cpu] profiling\n```\n\n::: tip\n默认情况下，生成的是 cpu 的火焰图，即 event 为`cpu`。可以用`--event`参数指定其他性能分析模式，见下文。\n:::\n\n## 获取已采集的 sample 的数量\n\n```\n$ profiler getSamples\n23\n```\n\n## 查看 profiling 状态\n\n```bash\n$ profiler status\n[cpu] profiling is running for 4 seconds\n```\n\n可以查看当前 profiler 在采样哪种`event`和采样时间。\n\n## 查看 profiler 自身的内存占用\n\n```\n$ profiler meminfo\nCall trace storage:   10244 KB\n      Dictionaries:      72 KB\n        Code cache:   12890 KB\n------------------------------\n             Total:   23206 KB\n```\n\n## 停止 profiler\n\n### 生成火焰图格式结果\n\n默认情况下，结果是 [Flame Graph](https://github.com/BrendanGregg/FlameGraph) 格式的 `html` 文件，也可以用 `-o` 或 `--format` 参数指定其他内容格式，包括 flat、traces、collapsed、flamegraph、tree、jfr、md。\n\n### 生成 LLM 友好的 Markdown 报告\n\n当 `--format md`（或 `md=N`）时，Arthas 会基于 async-profiler 的 `collapsed` 输出生成结构化的 Markdown，便于直接复制到 LLM 或在终端里 grep。报告包含：\n\n- Top N Hotspots（self）\n- Call Tree（调用树，按采样占比排序截断）\n- Function Details（每个热点函数的 Top stacks）\n\n```bash\n$ profiler stop --format md\n```\n\n指定输出文件（可选）：\n\n```bash\n$ profiler stop --format md --file /tmp/profile.md\n```\n\n如果 `--file` 以 `.md` 结尾且未指定 `--format`，将自动推断为 Markdown 输出：\n\n```bash\n$ profiler stop --file /tmp/profile.md\n```\n\n指定 TopN（可选，默认 10）：\n\n```bash\n$ profiler stop --format md=20\n```\n\n```bash\n$ profiler stop --format flamegraph\nprofiler output file: /tmp/test/arthas-output/20211207-111550.html\nOK\n```\n\n在`--file`参数指定的文件名后缀为 `html` 或 `jfr` 时，文件格式可以被推断出来。比如`--file /tmp/result.html` 将自动生成火焰图。\n\n## 通过浏览器查看 arthas-output 下面的 profiler 结果\n\n默认情况下，arthas 使用 3658 端口，则可以打开： [http://localhost:3658/arthas-output/](http://localhost:3658/arthas-output/) 查看到`arthas-output`目录下面的 profiler 结果：\n\n![](/images/arthas-output.jpg)\n\n点击可以查看具体的结果：\n\n![](/images/arthas-output-svg.jpg)\n\n::: tip\n如果是 chrome 浏览器，可能需要多次刷新。\n:::\n\n## profiler 支持的 events\n\n在不同的平台，不同的 OS 下面，支持的 events 各有不同。比如在 macos 下面：\n\n```bash\n$ profiler list\nBasic events:\n  cpu\n  alloc\n  lock\n  wall\n  itimer\n  ctimer\n```\n\n在 linux 下面\n\n```bash\n$ profiler list\nBasic events:\n  cpu\n  alloc\n  lock\n  wall\n  itimer\n  ctimer\nJava method calls:\n  ClassName.methodName\nPerf events:\n  page-faults\n  context-switches\n  cycles\n  instructions\n  cache-references\n  cache-misses\n  branch-instructions\n  branch-misses\n  bus-cycles\n  L1-dcache-load-misses\n  LLC-load-misses\n  dTLB-load-misses\n  rNNN\n  pmu/event-descriptor/\n  mem:breakpoint\n  trace:tracepoint\n  kprobe:func\n  uprobe:path\n```\n\n如果遇到 OS 本身的权限/配置问题，然后缺少部分 event，可以参考 [async-profiler 的文档](https://github.com/jvm-profiling-tools/async-profiler)。\n\n可以使用 `check` action 测试某个 event 是否可用，此 action 的参数格式与 start 一致。\n\n可以用`--event`参数指定要采样的事件，比如 `alloc` 表示分析内存分配情况：\n\n```bash\n$ profiler start --event alloc\n```\n\n## 恢复采样\n\n```bash\n$ profiler resume\nStarted [cpu] profiling\n```\n\n`start`和`resume`的区别是：`start`会清除已有的分析结果重新开始，`resume`则会保留已有的结果，将新的分析结果附加到已有结果中。\n\n通过执行`profiler getSamples`可以查看 samples 的数量来验证。\n\n## Dump 分析结果\n\n```bash\n$ profiler dump\nOK\n```\n\n`dump` action 将性能分析的结果保存到默认文件或指定的文件中，但 profiling 过程不会停止。例如，如果使用 `start` action 启动 profiling，5 秒后执行 `dump` action，2 秒后再次执行 `dump` action，将会得到 2 个结果文件，第一个文件包括 0\\~5 秒的分析结果，第二个文件包括 0\\~7 秒的分析结果。\n\n## 使用`execute`来执行复杂的命令\n\n比如开始采样：\n\n```bash\nprofiler execute 'start,framebuf=5000000'\n```\n\n停止采样，并保存到指定文件里：\n\n```bash\nprofiler execute 'stop,file=/tmp/result.html'\n```\n\n具体的格式参考： [arguments.cpp](https://github.com/async-profiler/async-profiler/blob/v2.9/src/arguments.cpp#L52)\n\n## 查看所有支持的 action\n\n```bash\n$ profiler actions\nSupported Actions: [resume, dumpCollapsed, getSamples, start, list, version, execute, meminfo, stop, load, dumpFlat, dump, actions, dumpTraces, status, check]\n```\n\n## 查看版本\n\n```bash\n$ profiler version\nAsync-profiler 2.9 built on May  8 2023\nCopyright 2016-2021 Andrei Pangin\n```\n\n## 配置 Java 栈深度\n\n可以使用 `-j` 或 `--jstackdepth` 选项指定最大 Java 栈深度。如果指定值大于默认值 2048，该选项会被忽略。当你不希望看到特别深的栈轨迹的时候，这个选项会很有用，以下是一个使用样例：\n\n```bash\nprofiler start -j 256\n```\n\n## 各线程分别进行 profiling\n\n可以使用 `-t` 或 `--threads` 标志选项令 profiling 对各线程分别进行，每个栈轨迹都会以指示单个线程的帧结束。\n\n```bash\nprofiler start -t\n```\n\n## 配置 include/exclude 来过滤数据\n\n如果应用比较复杂，生成的内容很多，想只关注部分 stack traces，可以通过 `--include/--exclude` 过滤 stack traces，`--include` 表示定义的匹配表达式必须出现在 stack traces，相反 `--exclude` 表示定义的匹配表达式一定不会出现在 stack traces。 匹配表达式可以以`*`开始或者结束,`*` 表示任何（可能为空）字符序列。 比如\n\n```bash\nprofiler stop --include 'java/*' --include 'com/demo/*' --exclude '*Unsafe.park*'\n```\n\n> `--include/--exclude` 都支持多次设置，但是需要配置在命令行的最后。也可使用短参数格式 `-I/-X`。\n> 注意`--include/--exclude`只支持在`stop`action或者带有`-d`/`--duration`参数的`start`action中指定，否则不生效。\n\n## 指定执行时间\n\n比如，希望 profiler 执行 300 秒自动结束，可以用 `-d`/`--duration` 参数为 start action 指定时间：\n\n```bash\nprofiler start --duration 300\n```\n\n## 生成 jfr 格式结果\n\n> 注意，jfr 只支持在 `start`时配置。如果是在`stop`时指定，则不会生效。\n\n```\nprofiler start --file /tmp/test.jfr\nprofiler start -o jfr\n```\n\n`file`参数支持一些变量：\n\n- 时间戳： `--file /tmp/test-%t.jfr`\n- 进程 ID： `--file /tmp/test-%p.jfr`\n\n生成的结果可以用支持 jfr 格式的工具来查看。比如：\n\n- JDK Mission Control ： https://github.com/openjdk/jmc\n- JProfiler ： https://github.com/alibaba/arthas/issues/1416\n\n## 控制分析结果的格式\n\n使用 `-s` 选项将结果中的 Fully qualified name 替换为简单名称，如 `demo.MathGame.main` 替换为 `MathGame.main`。使用 `-g` 选项指定输出方法签名，如 `demo.MathGame.main` 替换为 `demo.MathGame.main([Ljava/lang/String;)V`。此外还有许多可调整分析结果格式的选项，可参考 [async-profiler 的 README 文档](https://github.com/async-profiler/async-profiler#readme) 以及 [async-profiler 的 Github Discussions](https://github.com/async-profiler/async-profiler/discussions) 等材料。\n\n例如，以下命令中，`-s` 将输出中的类名称指定为简短格式，`-g` 显示方法的完整签名，`-a` 标注出 Java 方法，`-l` 为原生方法增加库名称，`--title` 为生成火焰图页面指定标题，`--minwidth` 将过滤火焰图中宽度为 15% 以下的帧，`--reverse` 将火焰图倒置。\n\n```\nprofiler stop -s -g -a -l --title <flametitle> --minwidth 15 --reverse\n```\n\n## 生成的火焰图里的 unknown\n\n- https://github.com/jvm-profiling-tools/async-profiler/discussions/409\n\n## 配置 locks/allocations 模式的阈值\n\n当使用 lock 或 alloc event 进行 profiling 时，可以使用 `--lock` 或 `--alloc` 配置阈值，比如下列命令：\n\n```bash\nprofiler start -e lock --lock 10ms\nprofiler start -e alloc --alloc 2m\n```\n\n会记录竞争时间超过 10ms 的锁（如果不指定时间单位，则使用 ns 为单位），或者以 2MB 的单位记录对内存的分配。\n\n## 配置 JFR 块\n\n当使用 JFR 作为输出格式时，可以使用 `--chunksize` 或 `--chunktime` 配置单个 JFR 块的大致容量（以 byte 为单位，默认 100 MB）和时间限制（默认值为 1 小时），比如：\n\n```bash\nprofiler start -f profile.jfr --chunksize 100m --chunktime 1h\n```\n\n## 将线程按照调度策略分组\n\n可以使用 `--sched` 标志选项将输出结果按照 Linux 线程调度策略分组，策略包括 BATCH/IDLE/OTHER。例如：\n\n```bash\nprofiler start --sched\n```\n\n火焰图的倒数第二行会标记不同的调度策略。\n\n## 仅用未销毁对象构建内存分析结果\n\n使用 `--live` 标志选项在内存分析结果中仅保留那些在分析过程结束时仍未被 JVM 回收的对象。该选项在排查 Java 堆内存泄露问题时比较有用。\n\n```bash\nprofiler start --live\n```\n\n## 配置收集 C 栈帧的方法\n\n使用 `--cstack MODE` 配置收集 native 帧的方法。候选模式有 fp (Frame Pointer), dwarf (DWARF unwind info), lbr (Last Branch Record, 从 Linux 4.1 在 Haswell 可用), and no (不收集 native 栈帧).\n\n默认情况下，C 栈帧会出现在 cpu、itimer、wall-clock、perf-events 模式中，而 Java 级别的 event 比如 alloc 和 lock 只收集 Java stack。\n\n```bash\nprofiler --cstack fp\n```\n\n此命令将收集 native 栈帧的 Frame Pointer 信息。\n\n## 当指定 Native 函数执行时开始/停止 Profiling\n\n使用 `--begin function` 和 `--end function` 选项，可以在指定的 Native 函数被执行时启动或终止性能分析。主要用途是分析特定的 JVM 阶段，比如 GC 和 Safepoint。需要使用特定 JVM 实现中的 Native 函数名，比如在 HotSpot JVM 中的 SafepointSynchronize::begin 和 SafepointSynchronize::end。\n\n### Time-to-Safepoint Profiling\n\n选项 `--ttsp` 实际上是 `--begin SafepointSynchronize::begin --end RuntimeService::record_safepoint_synchronized` 的一个别名。它是一种约束，而不是独立的事件类型。无论选择哪种事件，Profiler 都可以正常工作，但只有在 VM 操作和 Safepoint 请求之间的事件会被记录下来。\n\n现在，当使用 `--ttsp` 选项并指定 JFR 输出格式时，`profiler` 会在生成的 JFR 文件中自动包含 profiler.Window 事件。这些事件表示每次 Time-to-Safepoint 暂停的时间区间，使您无需依赖 JVM 日志即可分析这些暂停。\n\n示例\n\n```bash\nprofiler start --begin SafepointSynchronize::begin --end RuntimeService::record_safepoint_synchronized\nprofiler start --ttsp --format jfr\n```\n\n生成的 JFR 文件将包含 profiler.Window 事件，可以使用 JDK Mission Control 等工具查看和分析这些事件。\n\n**注意事项:**\n\n- profiler.Window 事件是通用的事件，适用于任何使用 --begin 和 --end 触发器的时间窗口，不仅限于 Safepoint 暂停。\n\n- 在分析长时间的 Safepoint 暂停时，profiler.Window 事件可帮助您识别造成延迟的原因。\n\n- 当使用 --ttsp 选项时，请确保使用 JFR 输出格式，以便能够生成并查看 profiler.Window 事件。\n\n## 使用 profiler 记录的 event 生成 JFR 文件\n\n用 `--jfrsync CONFIG` 选项可以指定配置启动 Java Flight Recording，输出的 jfr 文件会包含所有常规的 JFR event，但采样的来源是由 profiler 提供的。\n\nCONFIG 参数:\n\n- 预置配置：CONFIG 可以是 profile，表示使用 $JAVA_HOME/lib/jfr 目录下预置的 profile 配置。\n- 自定义配置文件：CONFIG 也可以是自定义的 JFR 配置文件（.jfc），此选项的值采用与 jcmd JFR.start 命令的 settings 选项相同的格式。\n- 指定 JFR 事件列表：现在，可以直接在 --jfrsync 中指定要启用的 JFR 事件列表，而无需创建 .jfc 文件。要指定事件列表，请以 + 开头，多个事件用 + 分隔。\n\n示例：\n\n使用预置的 profile 配置启动 JFR：\n\n```bash\nprofiler start -e cpu --jfrsync profile -f combined.jfr\n```\n\n直接指定 JFR 事件列表，例如启用 jdk.YoungGarbageCollection 和 jdk.OldGarbageCollection 事件：\n\n```bash\nprofiler start -e cpu --jfrsync +jdk.YoungGarbageCollection+jdk.OldGarbageCollection -f combined.jfr\n```\n\n**注意事项**\n\n- 当指定事件列表时，由于逗号 , 用于分隔不同的选项，因此事件之间使用加号 + 分隔。\n- 如果 --jfrsync 参数不以 + 开头，则被视为预置配置名或 .jfc 配置文件的路径。\n- 直接指定事件列表在目标应用运行在容器中时特别有用，无需额外的文件操作。\n\n## 周期性保存结果\n\n使用 `--loop TIME` 可以持续运行 profiler 并周期性保存结果。选项格式可以是具体时间 hh:mm:ss 或以秒、分钟、小时或天计算的时间间隔。需要确保指定的输出文件名中包含时间戳，否则每次输出的结果都会覆盖上次保存的结果。以下命令持续执行 profiling 并将每个小时内的记录保存到一个 jfr 文件中。\n\n> 如果没有指定 `-f` 参数，则不会保存任何内容。如果 `-f` 参数里没有 `%t`，则会循环保存到同一个文件里。\n\n```bash\nprofiler start --loop 1h -f /var/log/profile-%t.jfr\n```\n\n## `--timeout` 选项\n\n```bash\nprofiler start --timeout 300s\n```\n\n这个选项指定 profiling 自动在多久后停止。该选项和 `--loop` 选项的格式一致，可以是时间点，也可以是一个时间间隔。这两个选项都是用于 `start` action。可参考 [async-profiler docs](https://github.com/async-profiler/async-profiler/blob/master/docs/ProfilerOptions.md) 了解更多信息。\n\n## `--wall` 选项\n\n通过 --wall 选项，可以同时进行 CPU 和 Wall Clock 的性能分析。\n\n1. 这种联合分析有助于更全面地识别和理解应用程序的性能瓶颈。\n2. 允许用户独立于 CPU 分析设置 Wall Clock 分析的采样间隔。比如，可以通过设置 -e cpu -i 10 --wall 200，将 CPU 采样间隔设为 10 毫秒，墙钟采样间隔设为 200 毫秒。\n3. 联合进行 CPU 和 Wall Clock 分析时，输出格式必须设置为 jfr。这一格式支持记录线程的状态信息（如 STATE_RUNNABLE 或 STATE_SLEEPING），从而区分不同类型的采样事件。\n\n可参考 [async-profiler Github pr#740](https://github.com/async-profiler/async-profiler/issues/740) 了解更多信息。\n\n影响：\n\nLinux 平台: 这个新功能仅在 Linux 平台上有效。macOS 上的 CPU 分析引擎已经基于 Wall clock 模式，因此没有额外的收益。\n性能开销: 启用 Wall clock 分析会增加性能开销，因此在同时分析 CPU 和 Wall clock 时，建议增加 Wall clock 的间隔。\n\n```bash\nprofiler start -e cpu -i 10 --wall 100 -f out.jfr\n```\n\n## `ctimer`事件\n\n`ctimer` 事件是一种新的 CPU 采样模式，基于 `timer_create`，提供了无需 `perf_events` 的精确 CPU 采样。\n\n在某些情况下，`perf_events` 可能不可用，例如由于 `perf_event_paranoid` 设置或 `seccomp` 限制，或者在容器环境中。虽然 itimer 事件可以在容器中工作，但可能存在采样不准确的问题。\n\n`ctimer` 事件结合了 `cpu` 和 `itimer` 的优点：\n\n- 高准确性：提供精确的 CPU 采样。\n- 容器友好：默认在容器中可用。\n- 低资源消耗：不消耗文件描述符。\n\n**请注意，`ctimer` 事件目前仅在 `Linux` 上支持，不支持 `macOS`。**\n可参考 [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/855) 了解更多信息。\n\n示例：\n\n```bash\nprofiler start -e ctimer -o jfr -f ./out-test.jfr\n```\n\n## `vtable`特性\n\n在某些应用程序中，大量的 CPU 时间花费在调用 `megamorphic` 的虚方法或接口方法上，这在性能分析中显示为 `vtable stub` 或 `itable stub`。这无法帮助我们了解特定调用点为何是`megamorphic` 以及如何优化它。\n\nvtable 特性可以在` vtable stub` 或 `itable stub` 之上添加一个伪帧，显示实际调用的对象类型。这有助于清楚地了解在特定调用点，不同接收者的比例。\n\n该特性默认禁用，可以通过 `-F vtable` 选项启用（或使用 `features=vtable`）。\n可参考 [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/736) 了解更多信息。\n\n示例：\n\n```bash\nprofiler start -F vtable\n```\n\n## `comptask` 特性\n\n`profiler` 采样 JIT 编译器线程以及 Java 线程，可以显示 JIT 编译所消耗的 CPU 百分比。然而，Java 方法的编译资源消耗各不相同，了解哪些特定的 Java 方法在编译时消耗最多的 CPU 时间非常有用。\n\n`comptask` 特性可以在 `C1/C2` 的堆栈跟踪中添加一个虚拟帧，显示当前正在编译的任务，即正在编译的 Java 方法。\n\n该特性默认禁用，可以通过` -F comptask` 选项启用（或使用 `features=comptask`）。\n可参考 [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/777) 了解更多信息。\n\n示例：\n\n```bash\nprofiler start -F comptask\n```\n\n## 配置替代的分析信号\n\n`profiler` 使用 `POSIX` 信号来进行性能分析。默认情况下，`SIGPROF` 用于 `CPU` 分析，`SIGVTALRM` 用于 `Wall-Clock` 分析。然而，如果应用程序也使用这些信号，或者希望同时运行多个 `profiler` 实例，这可能会导致信号冲突。\n\n现在，可以使用 `signal` 参数来配置用于分析的信号，以避免冲突。\n可参考 [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/759) 了解更多信息。\n\n语法\n\n```bash\nprofiler start --signal <信号号码>\n```\n\n如果需要分别指定 CPU 和 Wall-Clock 分析的信号，可以使用以下语法：\n\n```bash\nprofiler start --signal <CPU信号号码>/<Wall信号号码>\n```\n\n## `--clock` 选项\n\n`--clock` 选项允许用户控制用于采样时间戳的时钟源。这对于需要将 `profiler` 的数据与其他工具的数据进行时间戳对齐的场景非常有用。\n\n用法\n\n```bash\nprofiler start --clock <tsc|monotonic>\n```\n\n参数\n\n- `tsc`：使用 CPU 的时间戳计数器（`RDTSC`）。这是默认选项，提供高精度的时间戳。\n- `monotonic`：使用操作系统的单调时钟（`CLOCK_MONOTONIC`）。这有助于在多种数据源之间对齐时间戳。\n  可参考 [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/723) 了解更多信息。\n\n示例 :\n\n使用 `CLOCK_MONOTONIC` 作为时间戳源：\n\n```bash\nprofiler start --clock monotonic\n```\n\n**注意事项:**\n\n- 当需要将 `profiler` 的数据与其他使用 `CLOCK_MONOTONIC` 的工具（例如 `perf`）的数据进行对齐时，使用 `--clock monotonic`。\n- 在使用 `jfrsync` 模式时，请谨慎使用 `--clock` 选项，因为 JVM 和 `profiler` 可能使用不同的时间戳源，这可能导致结果不一致。\n\n## `--norm` 选项\n\n在 Java 20 及更早的版本中，编译器为 `lambda` 表达式生成的方法名称包含唯一的数字后缀。例如，同一代码位置定义的 `lambda` 表达式，可能会生成多个不同的帧名称，因为每个 `lambda` 方法的名称都会附加一个唯一的数字后缀（如 `lambda$method$0`、`lambda$method$1` 等）。这会导致逻辑上相同的堆栈无法在火焰图中合并，增加了性能分析的复杂性。\n\n为了解决这个问题，`profiler` 新增了 `--norm` 选项，可以在生成输出时自动规范化方法名称，去除这些数字后缀，使相同的堆栈能够正确地合并。\n可参考 [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/832) 了解更多信息。\n\n**示例:**\n\n生成规范化的火焰图:\n\n```bash\nprofiler start --norm\n```\n"

You can set it with -n option.\n```\n\n### 据执行时间来过滤\n\n```bash\n$ stack demo.MathGame primeFactors '#cost>5'\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 35 ms.\nts=2018-12-04 01:35:58;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    @demo.MathGame.run()\n        at demo.MathGame.main(MathGame.java:16)\n```\n"

You can set it with -n option.\n```\n\n### 包含 jdk 的函数\n\n- `--skipJDKMethod <value> ` skip jdk method trace, default value true.\n\n默认情况下，trace 不会包含 jdk 里的函数调用，如果希望 trace jdk 里的函数，需要显式设置`--skipJDKMethod false`。\n\n```bash\n$ trace --skipJDKMethod false demo.MathGame run\nPress Q or Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 60 ms.\n`---ts=2019-12-04

trace demo.MathGame run '#cost > 10'\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 41 ms.\n`---ts=2018-12-04 01:12:02;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[12.033735ms] demo.MathGame:run()\n        +---[0.006783ms]

是不是很眼熟，没错，在 JProfiler 等收费软件中你曾经见识类似的功能，这里你将可以通过命令就能打印出指定调用路径。 友情提醒下，`trace` 在执行的过程中本身是会有一定的性能开销，在统计的报告中并未像 JProfiler 一样预先减去其自身的统计开销。所以这统计出来有些许的不准，渲染路径上调用的类、方法越多，性能偏差越大。但还是能让你看清一些事情的。\n- [12.033735ms] 的含义，`12.033735` 的含义是：当前节点在当前步骤的耗时，单位为毫秒\n- [0,0,0ms,11]xxx:yyy() [throws Exception]，对该方法中相同的方法调用进行了合并，`0,0,0ms,11` 表示方法调用耗时，`min,max,total,count`；`throws Exception` 表明该方法调用中存在异常返回\n- 这里存在一个统计不准确的问题，就是所有方法耗时加起来可能会小于该监测方法的总耗时，这个是由于 Arthas 本身的逻辑会有一定的耗时\n\n### trace 多个类或者多个函数\n\ntrace 命令只会 trace 匹配到的函数里的子调用，并不会向下 trace 多层。因为 trace 是代价比较贵的，多层 trace 可能会导致最终要 trace 的类和函数非常多。\n\n可以用正则表匹配路径上的多个类和函数，一定程度上达到多层 trace 的效果。\n\n```bash\ntrace -E com.test.ClassA|org.test.ClassB method1|method2|method3\n```\n\n### 排除掉指定的类\n\n使用 `--exclude-class-pattern` 参数可以排除掉指定的类，比如：\n\n```bash\ntrace javax.servlet.Filter * --exclude-class-pattern com.demo.TestFilter\n```\n\n## 动态 trace\n\n::: tip\n3.3.0 版本后支持。\n:::\n\n打开终端 1，trace 上面 demo 里的`run`函数，可以看到打印出 `listenerId: 1`：\n\n```bash\n[arthas@59161]$ trace demo.MathGame run\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 112 ms, listenerId: 1\n`---ts=2020-07-09 16:48:11;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[1.389634ms] demo.MathGame:run()\n        `---[0.123934ms] demo.MathGame:primeFactors() #24 [throws Exception]\n\n`---ts=2020-07-09 16:48:12;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[3.716391ms] demo.MathGame:run()\n        +---[3.182813ms] demo.MathGame:primeFactors() #24\n        `---[0.167786ms] demo.MathGame:print() #25\n```\n\n现在想要深入子函数`primeFactors`，可以打开一个新终端 2，使用`telnet localhost 3658`连接上 arthas，再 trace `primeFactors`时，指定`listenerId`。\n\n```bash\n[arthas@59161]$ trace demo.MathGame primeFactors --listenerId 1\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 34 ms, listenerId: 1\n```\n\n这时终端 2 打印的结果，说明已经增强了一个函数：`Affect(class count: 1 , method count: 1)`，但不再打印更多的结果。\n\n再查看终端 1，可以发现 trace 的结果增加了一层，打印了`primeFactors`函数里的内容：\n\n```bash\n`---ts=2020-07-09 16:49:29;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[0.492551ms] demo.MathGame:run()\n        `---[0.113929ms] demo.MathGame:primeFactors() #24 [throws Exception]\n            `---[0.061462ms] demo.MathGame:primeFactors()\n                `---[0.001018ms] throw:java.lang.IllegalArgumentException() #46\n\n`---ts=2020-07-09 16:49:30;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[0.409446ms] demo.MathGame:run()\n        +---[0.232606ms] demo.MathGame:primeFactors() #24\n        |   `---[0.1294ms] demo.MathGame:primeFactors()\n        `---[0.084025ms] demo.MathGame:print() #25\n```\n\n通过指定`listenerId`的方式动态 trace，可以不断深入。另外 `watch`/`tt`/`monitor`等命令也支持类似的功能。\n\n## trace 结果时间不准确问题\n\n比如下面的结果里：`0.705196 > (0.152743 + 0.145825)`\n\n```bash\n$ trace demo.MathGame run -n 1\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 66 ms, listenerId: 1\n`---ts=2021-02-08 11:27:36;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@232204a1\n    `---[0.705196ms] demo.MathGame:run()\n        +---[0.152743ms] demo.MathGame:primeFactors() #24\n        `---[0.145825ms] demo.MathGame:print() #25\n```\n\n那么其它的时间消耗在哪些地方？\n\n1. 没有被 trace 到的函数。比如`java.*` 下的函数调用默认会忽略掉。通过增加`--skipJDKMethod false`参数可以打印出来。\n\n   ```bash\n   $ trace demo.MathGame run --skipJDKMethod false\n   Press Q or Ctrl+C to abort.\n   Affect(class count: 1 , method count: 1) cost in 35 ms, listenerId: 2\n   `---ts=2021-02-08 11:27:48;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@232204a1\n       `---[0.810591ms] demo.MathGame:run()\n           +---[0.034568ms] java.util.Random:nextInt() #23\n           +---[0.119367ms] demo.MathGame:primeFactors() #24 [throws Exception]\n           +---[0.017407ms] java.lang.StringBuilder:<init>() #28\n

java.lang.Exception:getMessage() #57\n           +---[0.015643ms] java.lang.StringBuilder:toString() #57\n           `---[0.086622ms] java.io.PrintStream:println() #57\n   ```\n\n2. 非函数调用的指令消耗。比如 `i++`, `getfield`等指令。\n\n3. 在代码执行过程中，JVM 可能出现停顿，比如 GC，进入同步块等。\n\n### 使用 -v 参数打印更多信息\n\n::: tip\nwatch/trace/monitor/stack/tt 命令都支持 `-v` 参数\n:::\n\n当命令执行之后，没有输出结果。有两种可能：\n\n1. 匹配到的函数没有被执行\n2. 条件表达式结果是 false\n\n但用户区分不出是哪种情况。\n\n使用 `-v`选项，则会打印`Condition express`的具体值和执行结果，方便确认。\n"

虽然很方便和灵活，但需要提前想清楚观察表达式的拼写，这对排查问题而言要求太高，因为很多时候我们并不清楚问题出自于何方，只能靠蛛丝马迹进行猜测。\n\n这个时候如果能记录下当时方法调用的所有入参和返回值、抛出的异常会对整个问题的思考与判断非常有帮助。\n\n于是乎，TimeTunnel 命令就诞生了。\n\n## 注意事项\n\n- tt 命令的实现是：把函数的入参/返回值等，保存到一个`Map<Integer, TimeFragment>`里，默认的大小是 100。\n- tt 相关功能在使用完之后，需要手动释放内存，否则长时间可能导致OOM。退出 arthas 不会自动清除 tt 的缓存 map。\n\n## 使用参考\n\n### 启动 Demo\n\n启动[快速入门](quick-start.md)里的`math-game`。\n\n### 记录调用\n\n对于一个最基本的使用来说，就是记录下当前方法的每次调用环境现场。\n\n```bash\n$ tt -t demo.MathGame primeFactors\nPress Ctrl+C to abort.\nAffect(class-cnt:1 ,

命令记录的过程，但如果遇到调用量非常大的方法，瞬间就能将你的 JVM 内存撑爆。\n\n    此时你可以通过 `-n` 参数指定你需要记录的次数，当达到记录次数时 Arthas 会主动中断 tt 命令的记录过程，避免人工操作无法停止的情况。\n\n  - `-m 1`\n\n    通过 `-m` 参数指定 Class 匹配的最大数量，防止匹配到的 Class 数量太多导致 JVM 挂起，默认值是 50。\n\n  - `-c <classloader hash>`\n\n    当同名类被多个 classloader 加载时，可以用 `-c` 指定只增强某个 classloader 加载的类。可以先用 `sc -d className` 查看具体的 classloader hash。\n\n- 表格字段说明\n\n| 表格字段  | 字段解释

Arthas 似乎很难区分出重载的方法\n  - 我只需要观察特定参数，但是 tt 却全部都给我记录了下来\n\n  条件表达式也是用 `\bOGNL` 来编写，核心的判断对象依然是 `Advice` 对象。除了 `tt` 命令之外，`watch`、`trace`、`stack` 命令也都支持条件表达式。\n\n- 解决方法重载\n\n  `tt -t *Test print params.length==1`\n\n  通过制定参数个数的形式解决不同的方法签名，如果参数个数一样，你还可以这样写\n\n  `tt -t *Test print 'params[1] instanceof Integer'`\n\n- 解决指定参数\n\n  `tt -t *Test print params[0].mobile==\"13989838402\"`\n\n- 构成条件表达式的 `Advice` 对象\n\n  前边看到了很多条件表达式中，都使用了 `params[0]`，有关这个变量的介绍，请参考[表达式核心变量](advice-class.md)\n\n### 检索调用记录\n\n当你用 `tt` 记录了一大片的时间片段之后，你希望能从中筛选出自己需要的时间片段，这个时候你就需要对现有记录进行检索。\n\n假设我们有这些记录\n\n```bash\n$ tt -l\n INDEX   TIMESTAMP            COST(ms)  IS-RET  IS-EXP   OBJECT         CLASS

对象。</span>\n\n### 查看调用信息\n\n对于具体一个时间片的信息而言，你可以通过 `-i` 参数后边跟着对应的 `INDEX` 编号查看到他的详细信息。\n\n```bash\n$ tt -i 1003\n INDEX            1003\n GMT-CREATE       2018-12-04 11:15:41\n COST(ms)

重做一次调用\n\n当你稍稍做了一些调整之后，你可能需要前端系统重新触发一次你的调用，此时得求爷爷告奶奶的需要前端配合联调的同学再次发起一次调用。而有些场景下，这个调用不是这么好触发的。\n\n`tt` 命令由于保存了当时调用的所有现场信息，所以我们可以自己主动对一个 `INDEX` 编号的时间片自主发起一次调用，从而解放你的沟通成本。此时你需要 `-p` 参数。通过 `--replay-times` 指定\n调用次数，通过 `--replay-interval` 指定多次调用间隔(单位 ms, 默认 1000ms)\n\n```bash\n$ tt -i 1004 -p\n RE-INDEX       1004\n GMT-REPLAY     2018-12-04 11:26:00\n OBJECT         0x4b67cf4d\n CLASS

          @Integer[2],\n                    @Integer[11],\n                    @Integer[17],\n                    @Integer[2531387],\n                ]\nTime fragment[1004] successfully replayed.\nAffect(row-cnt:1) cost in 14 ms.\n```\n\n你会发现结果虽然一样，但调用的路径发生了变化，由原来的程序发起变成了 Arthas 自己的内部线程发起的调用了。\n\n### 观察表达式\n\n`-w, --watch-express` 观察时空隧道使用`ognl` 表达式\n\n- 使用[表达式核心变量](advice-class.md)中所有变量作为已知条件编写表达式。\n\n```bash\n[arthas@10718]$ tt -t demo.MathGame run -n 5\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 56 ms, listenerId:

1000\n@Integer[46]\n```\n\n注意这里使用 `com.taobao.arthas.core.advisor.Advice#getLoader`加载,使用精确`classloader` [ognl](ognl.md)更好。\n\n高级用法 [获取 spring context 调用 bean 方法](https://github.com/alibaba/arthas/issues/482)\n\n- 需要强调的点\n  1. **ThreadLocal 信息丢失**\n\n     很多框架偷偷的将一些环境变量信息塞到了发起调用线程的 ThreadLocal 中，由于调用线程发生了变化，这些 ThreadLocal 线程信息无法通过 Arthas 保存，所以这些信息将会丢失。\n\n     一些常见的 CASE 比如：鹰眼的 TraceId 等。\n\n  2. **引用的对象**\n\n     需要强调的是，`tt` 命令是将当前环境的对象引用保存起来，但仅仅也只能保存一个引用而已。如果方法内部对入参进行了变更，或者返回的对象经过了后续的处理，那么在 `tt` 查看的时候将无法看到当时最准确的值。这也是为什么 `watch` 命令存在的意义。\n\n### 通过索引删除指定的 tt 记录\n\n```\ntt -d -i 1001\n```\n\n### 清除所有的 tt 记录\n\n```\ntt --delete-all\n```\n"

    "content": "# Arthas Tunnel\n\n通过 Arthas Tunnel Server/Client 来远程管理/连接多个 Agent。\n\n比如，在流式计算里，Java 进程可以是在不同的机器启动的，想要使用 Arthas 去诊断会比较麻烦，因为用户通常没有机器的权限，即使登录机器也分不清是哪个 Java 进程。\n\n在这种情况下，可以使用 Arthas Tunnel Server/Client。\n\n参考:\n\n- 1: [Web Console](web-console.md)\n- 2: [Arthas Spring Boot Starter](spring-boot-starter.md)\n\n## 下载部署 arthas tunnel server\n\n[https://github.com/alibaba/arthas/releases](https://github.com/alibaba/arthas/releases)\n\n- 从 Maven 仓库下载：[![](https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square \"Arthas\")](https://arthas.aliyun.com/download/arthas-tunnel-server/latest_version?mirror=aliyun)\n\n- 从 Github Releases 页下载： [https://github.com/alibaba/arthas/releases](https://github.com/alibaba/arthas/releases)\n\nArthas tunnel server 是一个 spring boot fat jar 应用，直接`java -jar`启动：\n\n```bash\njava -jar  arthas-tunnel-server.jar\n```\n\n默认情况下，arthas tunnel server 的 web 端口是`8080`，arthas agent 连接的端口是`7777`。\n\n启动之后，可以访问 [http://127.0.0.1:8080/](http://127.0.0.1:8080/) ，再通过`agentId`连接到已注册的 arthas agent 上。\n\n通过 Spring Boot 的 Endpoint，可以查看到具体的连接信息： [http://127.0.0.1:8080/actuator/arthas](http://127.0.0.1:8080/actuator/arthas) ，登录用户名是`arthas`，密码在 arthas tunnel server 的日志里可以找到，比如：\n\n```\n32851 [main] INFO  o.s.b.a.s.s.UserDetailsServiceAutoConfiguration\n\nUsing generated security password: f1dca050-3777-48f4-a577-6367e55a78a2\n```\n\n## 启动 arthas 时连接到 tunnel server\n\n在启动 arthas，可以传递`--tunnel-server`参数，比如：\n\n```bash\nas.sh --tunnel-server 'ws://127.0.0.1:7777/ws'\n```\n\n也可以使用下面的测试地址（不保证一直可用）：\n\n```bash\nas.sh --tunnel-server 'ws://47.75.156.201:80/ws'\n```\n\n- 如果有特殊需求，可以通过`--agent-id`参数里指定 agentId。默认情况下，会生成随机 ID。\n\nattach 成功之后，会打印出 agentId，比如：\n\n```bash\n  ,---.  ,------. ,--------.,--.  ,--.  ,---.   ,---.\n /  O  \\ |  .--. ''--.  .--'|  '--'  | /  O  \\ '   .-'\n|  .-.  ||  '--'.'   |  |   |  .--.  ||  .-.  |`.  `-.\n|  | |  ||  |\\  \\    |  |   |  |  |  ||  | |  |.-'    |\n`--' `--'`--' '--'   `--'   `--'  `--'`--' `--'`-----'\n\n\nwiki      https://arthas.aliyun.com/doc\ntutorials https://arthas.aliyun.com/doc/arthas-tutorials.html\nversion   3.1.2\npid       86183\ntime      2019-08-30 15:40:53\nid        URJZ5L48RPBR2ALI5K4V\n```\n\n如果是启动时没有连接到 tunnel server，也可以在后续自动重连成功之后，通过 session 命令来获取 agentId：\n\n```bash\n[arthas@86183]$ session\n Name           Value\n-----------------------------------------------------\n JAVA_PID       86183\n SESSION_ID     f7273eb5-e7b0-4a00-bc5b-3fe55d741882\n AGENT_ID       URJZ5L48RPBR2ALI5K4V\n TUNNEL_SERVER  ws://47.75.156.201:80/ws\n```\n\n以上面的为例，在浏览器里访问 [http://47.75.156.201/arthas/?port=80](http://47.75.156.201/arthas/?port=80) ，输入 `agentId`，就可以连接到本机上的 arthas 了。\n\n![](/images/arthas-tunnel-server.png)\n\n## 最佳实践\n\n::: tip\n注意，agentId 要保持唯一，否则会在 tunnel server 上冲突，不能正常工作。\n:::\n\n如果 arthas agent 配置了 `appName`，则生成的 agentId 会带上`appName`的前缀。\n\n比如在加上启动参数：`as.sh --tunnel-server 'ws://127.0.0.1:7777/ws' --app-name demoapp` ，则生成的 agentId 可能是`demoapp_URJZ5L48RPBR2ALI5K4V`。\n\nTunnel server 会以`_`做分隔符，提取出`appName`，方便按应用进行管理。\n\n::: tip\n另外，也可以在解压的 arthas 目录下的 `arthas.properties`，或者在 spring boot 应用的`application.properties`里配置`appName`。\n:::\n\n## Tunnel Server 的管理页面\n\n::: tip\n需要在 tunnel-server 的`application.properties`里配置 `arthas.enable-detail-pages=true`，也可以用命令行参数指定： `java -Darthas.enable-detail-pages=true -jar arthas-tunnel-server.jar`\n\n支持的配置项： [tunnel-server application.properties](https://github.com/alibaba/arthas/blob/master/tunnel-server/src/main/resources/application.properties)\n\n**注意，开放管理页面有风险！管理页面没有安全拦截功能，务必自行增加安全措施，不要开放到公网。**\n:::\n\n在本地启动 tunnel-server，然后使用`as.sh` attach，并且指定应用名`--app-name test`：\n\n```\n$ as.sh --tunnel-server 'ws://127.0.0.1:7777/ws' --app-name test\ntelnet connecting to arthas server... current timestamp is 1627539688\nTrying 127.0.0.1...\nConnected to 127.0.0.1.\nEscape character is '^]'.\n  ,---.  ,------. ,--------.,--.  ,--.  ,---.   ,---.\n /  O  \\ |  .--.

    "content": "# Introduction\n\n![](/images/arthas.png)\n\nArthas is a Java diagnostic tool open-sourced by Alibaba middleware team. It is widely adopted and popular among the developers inside Alibaba. Arthas helps developers in trouble-shooting issues in production environment for Java based applications without modifying code or restarting servers.\n\n## Background\n\nOftentimes the production system network is inaccessible from local development environment. If issues are encountered in production systems, it is impossible to use IDE to debug the application remotely. What's even worse, debugging in production environment is unacceptable, as it will suspend all the threads, leading to services downtime.\n\nDevelopers could always try to reproduce the same issue on the test/staging environment. However, this is tricky as some issues cannot be reproduced easily in a different environment, or even disappear once restarted.\n\nAnd if you're thinking of adding some logs to your code to help trouble-shoot the issue, you will have to go through the following lifecycle: test, staging, and then to production. Time is money! This approach is inefficient! Worse still, the issue may not be fixed since it might be irreproducible once the JVM is restarted, as described above.\n\nArthas is built to solve these issues. A developer can troubleshoot production issues on the fly. No JVM restart, no additional code changes. Arthas works as an observer, that is, it will never suspend your running threads.\n\n## Key features\n\n- Check whether a class is loaded? Or where the class is loaded from? (Useful for trouble-shooting jar file conflicts)\n- Decompile a class to ensure the code is running as expected.\n- Check classloader statistics, e.g. the number of classloaders, the number of classes loaded per classloader, the classloader hierarchy, possible classloader leaks, etc.\n- Check the method invocation details, e.g. method parameter, returned values, exceptions and etc.\n- Check the stack trace of specified method invocation. This is useful when a developer wants to know the caller of the method.\n- Trace the method invocation to find slow sub-invocations.\n- Monitor method invocation statistics, e.g. QPS (Query Per Second), RT (Return Time), success rate and etc.\n- Monitor system metrics, thread states and CPU usage, GC statistics and etc.\n- Supports command line interactive mode, with auto-complete feature enabled.\n- Supports telnet and WebSocket, which enables both local and remote diagnostics with command line and browsers.\n- Supports profiler/Flame Graph\n- Support get objects in the heap that are instances of the specified class.\n- Supports JDK 6+ (version 4.x no longer supports JDK 6 and JDK 7)\n- Supports Linux/Mac/Windows\n\n**If you are using Arthas, please let us know. Your feedback is very important to us: [View](https://github.com/alibaba/arthas/issues/111)**\n\n## Contributors\n\n[![](https://opencollective.com/arthas/contributors.svg?width=890&button=false)](https://github.com/alibaba/arthas/graphs/contributors)\n"

    "content": "# Arthas Async Jobs\n\n[`Async Jobs` online tutorial](https://arthas.aliyun.com/doc/arthas-tutorials?language=en&id=case-async-jobs)\n\nAsynchronous jobs in arthas. The idea is borrowed from [linux jobs](http://man7.org/linux/man-pages/man1/jobs.1p.html).\n\n## 1. Use & to run the command in the background\n\nFor example, execute the trace command in the background:\n\n```bash\ntrace Test t &\n```\n\nBy doing this, the current command is put to the background to run, you can continue to execute other commands in the console.\n\n## 2. List background jobs\n\nIf you want to list all background jobs, you can execute the `jobs` command and the results are as follows:\n\n```bash\n$ jobs\n[10]*\n       Stopped           watch com.taobao.container.Test test \"params[0].{? #this.name == null }\" -x 2\n       execution count : 19\n       start time      : Fri Sep 22 09:59:55 CST 2017\n       timeout date    : Sat Sep 23 09:59:55 CST 2017\n       session         : 3648e874-5e69-473f-9eed-7f89660b079b (current)\n```\n\nYou can see that there is currently a background job executing:\n\n- job id is 10, `*` indicates that this job is created by the current session.\n- status is `Stopped`\n- execution count is the number of executions, which have been executed 19 times since the start.\n- timeout date: timeout timestamp, when the time exceeds this timestamp, the job will be automatically timeout and exit.\n\n## 3. Suspend and cancel job\n\nWhen the job is executing in the foreground, for example, directly executing the command `trace Test t`, or executing the background job command `trace Test t &`, then putting the job back to the foreground via `fg` command, the console cannot continue to execute other command, but can receive and process the following keyboard events:\n\n- ‘ctrl + z’: Suspends the job, the job status will change to `Stopped`, and the job can be restarted by `bg <job-id>` or `fg <job-id>`\n- ‘ctrl + c’: Stops the job\n- ‘ctrl + d’: According to linux semantics this should lead to exit the terminal, right now Arthas has not implemented this yet, therefore simply ignore this keystroke.\n\n## 4. fg/bg, switch the job from the foreground to the background, and vise verse\n\n- When a job is executed in the background or in suspended status (use `ctrl + z` to suspend job), `fg <job-id>` can transfer the job to the foreground to continue to run.\n- When a job is in suspended status (use `ctrl + z` to suspend job), `bg <job-id>` can put the job to the background to continue to run.\n- A job created by other session can only be put to the foreground to run by using `fg` in the current session.\n\n## 5. Redirect the output\n\nThe job output can be redirect to the specified file by `>` or `>>`, and can be used together with `&`. By doing this, you can achieve running commands asynchronously, for example:\n\n```bash\n$ trace Test t >> test.out &\n```\n\nAt this time, the trace command will be executed in the background, and the result will be output to the `test.out` file under the `working directory` of the application. You can continue to execute other commands. And you can view the command execution result in the file. You can execute the `pwd` command to view the `working directory` of the current application.\n\n```bash\n$ cat test.out\n```\n\nIf no redirect file is specified, the result will be output to the `~/logs/arthas-cache/` directory, for example:\n\n```bash\n$ trace Test t >> &\njob id : 2\ncache location : /Users/admin/logs/arthas-cache/28198/2\n```\n\nAt this time, the command will be executed asynchronously in the background, and the result will be asynchronously saved in the file (`~/logs/arthas-cache/${PID}/${JobId}`);\n\n- At this time, the execution of the task is not affected by the session disconnection; the default timeout period of the task is 1 day, and the default timeout period can be modified through the global `options` command;\n- The result of this command will be output asynchronously to the file; at this time, regardless of whether `save-result` is true or not, the result will not be written asynchronously to `~/logs/arthas-cache/result.log`.\n\n## 6. Stop job\n\nIf you want to stop background job, just `kill <job-id>`.\n\n## 7. Others\n\n- Support up to 8 commands at the same time to redirect the output to the log files.\n- Do not open too many background jobs at the same time to avoid negative performance effect to the target JVM.\n- If you do not want to stop the Arthas service and continue to perform background tasks, you can exit the Arthas console by executing `quit` command (`stop` command will stop the Arthas service)\n"

The priority of the command line is higher than that of the configuration file.\n- If only `username` is configured and no `password` is configured, a random password will be generated and printed in `~/logs/arthas/arthas.log`\n\n  ```\n  Using generated security password: 0vUBJpRIppkKuZ7dYzYqOKtranj4unGh\n  ```\n\n## Local connection does not require authentication\n\nBy default, there are configurations in the `arthas.properties` file:\n\n```\narthas.localConnectionNonAuth=true\n```\n\nWhen the password is configured, connect from localhost, the authentication is not required. The default configuration value is true, which is convenient for local connection. Authentication is only required when connecting remotely.\n\n## Authenticate in the telnet console\n\nAfter connecting to arthas, directly executing the command will prompt for authentication:\n\n```bash\n[arthas@37430]$ help\nError! command not permitted, try to use 'auth' command to authenticates.\n```\n\nUse the `auth` command to authenticate, and you can execute other commands after success.\n\n```\n[arthas@37430]$ auth ppp\nAuthentication result: true\n```\n\n- The user can be specified by the `--username` option, the default value is `arthas`.\n\n## Web console Authentication\n\nOpen the browser, there will be a pop-up window prompting you to enter your username and password.\n\nAfter success, you can directly connect to the web console.\n\n## HTTP API Authentication\n\n### HTTP Authorization Header(recommended)\n\nArthas uses the HTTP standard Basic Authorization.\n\n- Reference: [https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication)\n\nFor example, if the user name is: `admin` and the password is `admin`, the combination is a string: `admin:admin`, the base64 result is: `YWRtaW46YWRtaW4=`, then the HTTP request adds the `Authorization` header:\n\n```bash\ncurl 'http://localhost:8563/api' \\\n  -H 'Authorization: Basic YWRtaW46YWRtaW4=' \\\n  --data-raw '{\"action\":\"exec\",\"command\":\"version\"}'\n```\n\n### URL parameters\n\nIt supports passing username and password in parameters. such as:\n\n```bash\ncurl 'http://localhost:8563/api?password=admin' \\\n  --data-raw '{\"action\":\"exec\",\"command\":\"version\"}'\n```\n"

Here `as` is suggested for the suffix of the filename, but in fact any suffix is acceptable.\n\n```bash\n➜  arthas git:(develop) cat /var/tmp/test.as\nhelp\ndashboard -n 1\nsession\nthread\nsc -d org.apache.commons.lang.StringUtils\n```\n\nNote:\n\n- Each command takes one line.\n- Batch mode execution times (via `-n`) must be explicitly specified for `dashboard`, otherwise batch script cannot terminate.\n- Commands such as `watch`/`tt`/`trace`/`monitor`/`stack` should include `-n` option to ensure the script can be able to quit.\n- Also consider to use `async` (for example: `watch c.t.X test returnObj > &`) to put commands run at background and get the output from the log file, see more from [asynchronous job](async.md)\n\n### Step 2: Run the script\n\nUse `-f` to specify the script file. By default the result will be output to the standard output, but you can redirect the output to the file like this:\n\n```bash\n./as.sh -f /var/tmp/test.as 56328 > test.out\n```\n\nUse `-c` also can specify the commands, like this:\n\n```bash\n./as.sh -c 'sysprop; thread' 56328 > test.out\n```\n\n### Step 3: Check the output\n\n```bash\ncat test.out\n```\n"

The greater number, the higher priority\n- STATE: thread state\n- CPU%: the ratio of CPU usage for the thread. For example, the sampling interval is 1000ms, and the incremental cpu time\n  of a thread is 100ms, then the cpu usage rate=100/1000=10%\n- DELTA_TIME: incremental CPU time of thread running after the last sampling in `second` format\n- TIME: total CPU time of the thread in `minute:second` format\n- INTERRUPTED: the thread interruption state\n- DAEMON: daemon thread or not\n\n### JVM internal threads\n\nAfter Java 8, it is supported to obtain the CPU time of JVM internal threads. These threads only have the name and CPU time,\nwithout ID and status information (display ID is -1).\n\nJVM activities can be observed through internal threads, such as GC, JIT compilation, etc., to perceive the overall status of JVM.\n\n- When the JVM heap/metaspace space is insufficient or OOM, it can be seen that the CPU usage of the GC threads is\n  significantly higher than other threads.\n- After executing commands such as `trace/watch/tt/redefine`, you can see that JIT threads activities become more frequent.\n  Because the JIT compilation data related to this class is cleared when the JVM hot update the class bytecode, it needs to be recompiled.\n\nJVM internal threads include the following:\n\n- JIT compilation thread: such as `C1 CompilerThread0`, `C2 CompilerThread0`\n- GC thread: such as `GC Thread0`, `G1 Young RemSet Sampling`\n- Other internal threads: such as`VM Periodic Task Thread`, `VM Thread`, `Service Thread`\n\n## Screenshot\n\n![](/images/dashboard.png \"dashboard\")\n"

If only JRE is installed, many JAVA command line tools and class libraries will be missing, and Arthas will not work properly. Here are two common ways to use JDK in Docker.\n\n### Use public JDK image\n\n- https://hub.docker.com/_/openjdk/\n\nsuch as:\n\n```\nFROM openjdk:8-jdk\n```\n\nor:\n\n```\nFROM openjdk:8-jdk-alpine\n```\n\n### Install via package management software\n\nsuch as:\n\n```bash\n# Install OpenJDK-8\nRUN apt-get update && \\\n    apt-get install -y openjdk-8-jdk && \\\n    apt-get install -y ant && \\\n    apt-get clean;\n\n# Fix certificate issues\nRUN apt-get update && \\\n    apt-get install ca-certificates-java && \\\n    apt-get clean && \\\n    update-ca-certificates -f;\n\n# Setup JAVA_HOME - useful for docker commandline\nENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/\nRUN export JAVA_HOME\n```\n\nor:\n\n```bash\nRUN yum install -y \\\n   java-1.8.0-openjdk \\\n   java-1.8.0-openjdk-devel\n\nENV JAVA_HOME /usr/lib/jvm/java-1.8.0-openjdk/\nRUN export JAVA_HOME\n```\n\n## Quick start with Docker\n\n1. Delete the existing `math-game` docker container (not necessary)\n\n   ```sh\n   $ docker stop math-game || true && docker rm math-game || true\n   ```\n\n1. Start `math-game`\n\n   ```sh\n   $ docker run --name math-game -it hengyunabc/arthas:latest /bin/sh -c \"java -jar /opt/arthas/math-game.jar\"\n   ```\n\n1. Start `arthas-boot` for diagnosis\n\n   ```sh\n   $ docker exec -it math-game /bin/sh -c \"java -jar /opt/arthas/arthas-boot.jar\"\n   * [1]: 9 jar\n\n   [INFO] arthas home: /opt/arthas\n   [INFO] Try to attach process 9\n   [INFO] Attach process 9 success.\n   [INFO] arthas-client connect 127.0.0.1 3658\n   ,---.  ,------. ,--------.,--.  ,--.  ,---.   ,---.\n   /  O  \\ |  .--.

Currently killercoda using java 11.\n\nThe value of `--classloaderclass` is the class name of classloader. It can only work when it matches a unique classloader instance.

    "content": "# FAQ\n\n::: tip\nFor questions that are not in this list, please search in issues. [https://github.com/alibaba/arthas/issues](https://github.com/alibaba/arthas/issues)\n:::\n\n### Where is the log file?\n\nLog file path: `~/logs/arthas/arthas.log`\n\n### telnet: connect to address 127.0.0.1: Connection refused\n\n1. Check the log `~/logs/arthas/arthas.log`\n2. Check the startup parameters of `as.sh`/`arthas-boot.jar`, whether a specific `port` is specified\n3. Use `netstat` to check the process of `LISTEN 3658` port, confirm it is a `java` process, and it is the process you want to diagnose\n4. If the process of `LISTEN 3658` port is not a `java` process, then the `3658` port is already occupied. You need to specify other ports in the startup parameters of `as.sh`/`arthas-boot.jar`.\n5. After confirming the process and port, try to connect with `telnet 127.0.0.1 3658`\n\nEssentially, `arthas` will start a `tcp server` within the application java process, and then use `telnet` to connect to it.\n\n1. The port may not match\n2. The process itself may have been suspended and cannot accept new connections\n\nIf there is `Arthas server already bind.` in the Arthas log\n\n1. It means that the `Arthas server` has been started before, check the file descriptors opened by the target process. If it is a `linux` environment, you can go to `/proc/$pid/fd`, use `ls -alh | grep arthas` to check whether the process has loaded the `arthas` related jar package.\n2. If not, it may be that other processes have started `arthas`, or the application has been restarted.\n\n### How much impact does Arthas attach have on the performance of the original process?\n\n[https://github.com/alibaba/arthas/issues/44](https://github.com/alibaba/arthas/issues/44)\n\n### target process not responding or HotSpot VM not loaded\n\ncom.sun.tools.attach.AttachNotSupportedException: Unable to open socket file: target process not responding or HotSpot VM not loaded\n\n1. Check whether the current user and the target java process are consistent. If they are inconsistent, switch to the same user. JVM can only attach java processes under the same user.\n2. Try to use `jstack -l $pid`. If the process does not respond, it means that the process may freeze and fail to respond to the JVM attach signal. So Arthas based on the attach mechanism cannot work. Try to use `jmap` heapdump to analyze.\n3. Try to attach math-game in [quick-start](quick-start.md).\n4. For more information: [https://github.com/alibaba/arthas/issues/347](https://github.com/alibaba/arthas/issues/347)\n\n### Can commands such as trace/watch enhance the classes in jdk?\n\nBy default, classes beginning with `java.` or the classes loaded by the `Bootstrap ClassLoader` are filtered out, but they can be turned on:\n\n```bash\noptions unsafe true\n```\n\nSee more at [options](options.md)\n\n::: tip\nTo support the jars appended by java.lang.instrument.Instrumentation#appendToBootstrapClassLoaderSearch need to enable unsafe.\n:::\n\n### How to view the result in `json` format\n\n```bash\noptions json-format true\n```\n\nSee more at [options](options.md)\n\n### Can arthas trace native methods\n\nNo.\n\n### Can arthas view the value of a variable in memory?\n\n1. You can use [`vmtool`](vmtool.md) command.\n2. You can use some tricks to intercept the object with the [`tt`](tt.md) command, or fetch it from a static method.\n\n### How to filter method with the same name?\n\nYou can used all variables in [fundamental fields in expressions](advice-class.md) for the condition express to filter method with the same name, you can use the number of parameters `params.length ==1`,parameter type `params[0] instanceof java.lang.Integer`,return value type `returnObj instanceof java.util.List` and so on in one or more combinations as condition express.\n\nYou can use `-v` to view the condition express result [https://github.com/alibaba/arthas/issues/1348](https://github.com/alibaba/arthas/issues/1348)\n\nexample [math-game](quick-start.md)\n\n```bash\nwatch demo.MathGame primeFactors '{params,returnObj,throwExp}' 'params.length >0 && returnObj instanceof java.util.List' -v\n```\n\n### How to watch or trace constructor?\n\n```bash\nwatch demo.MathGame <init> '{params,returnObj,throwExp}' -v\n```\n\n### How to watch or trace inner classes?\n\nIn the JVM specification the name of inner classes is `OuterClass$InnerClass`.\n\n```bash\nwatch OuterClass$InnerClass\n```\n\n### Does it support watch and trace lambda classes?\n\nFor classes generated by lambda, will be skipped because the JVM itself does not allow enhancements to classes generated by lambda.\n\n- [https://github.com/alibaba/arthas/issues/1225](https://github.com/alibaba/arthas/issues/1225)\n\n### Enter Unicode characters\n\nConvert Unicode characters to `\\u` representation:\n\n```bash\nognl '@java.lang.System@out.println(\"Hello \\u4e2d\\u6587\")'\n```\n\n### java.lang.ClassFormatError: null, skywalking arthas compatible use\n\nWhen error log appear `java.lang.ClassFormatError: null`, it is usually modified by other bytecode tools that are not compatible with arthas modified bytecode.\n\nFor example: use skywalking V8.1.0 below [cannot trace, watch classes enhanced by skywalking agent](https://github.com/alibaba/arthas/issues/1141), V8.1.0 or above is compatible, refer to skywalking configuration for more details. [skywalking compatible with other javaagent bytecode processing](https://github.com/apache/skywalking/blob/master/docs/en/FAQ/Compatible-with-other-javaagent-bytecode-processing.md#).\n\n#### class redefinition failed: attempted to change the schema (add/remove fields)\n\nReference: [https://github.com/alibaba/arthas/issues/2165](https://github.com/alibaba/arthas/issues/2165)\n\n### Can I use arthas offline?\n\nYes. Just download the full size package and unzip it, refer to: [Download](download.md).\n\n### How to use the specified version of Arthas without using the automatic upgrade version?\n\n1. When starting `as.sh`/`arthas-boot.jar`, you can specify it with the `--use-version` parameter.\n2. Download the full package, unzip it, and cd to the arthas directory to start. In this case, the version in the current directory will be used.\n\n### Attach the process with pid 1 in docker/k8s failed\n\nReference: [https://github.com/alibaba/arthas/issues/362#issuecomment-448185416](https://github.com/alibaba/arthas/issues/362#issuecomment-448185416)\n\n### Why is the new version of Arthas downloaded, but the old version is connected?\n\nFor example, the started version of `as.sh/arthas-boot.jar` is 3.5._, but after connecting, the printed arthas version is 3.4._.\n\nIt may be that the target process has been diagnosed with the old version of arthas before. You can execute `stop` to stop the old version of arthas, and then reuse the new version to attach.\n\n### The spring bean cglib object is obtained in the ognl expression, but the field is null\n\nReference:\n\n- [https://github.com/alibaba/arthas/issues/1802](https://github.com/alibaba/arthas/issues/1802)\n- [https://github.com/alibaba/arthas/issues/1424](https://github.com/alibaba/arthas/issues/1424)\n"

    "content": "# getstatic\n\n[`getstatic` online tutorial](https://arthas.aliyun.com/doc/arthas-tutorials.html?language=en&id=command-getstatic)\n\n## Usage\n\n- It is recommended to use the [OGNL] (ognl.md) command, which will be more flexible.\n\nCheck the static fields of classes conveniently, the usage is `getstatic class_name field_name`.\n\n```bash\n$ getstatic demo.MathGame random\nfield: random\n@Random[\n    serialVersionUID=@Long[3905348978240129619],\n    seed=@AtomicLong[120955813885284],\n    multiplier=@Long[25214903917],\n    addend=@Long[11],\n    mask=@Long[281474976710655],\n    DOUBLE_UNIT=@Double[1.1102230246251565E-16],\n    BadBound=@String[bound must be positive],\n    BadRange=@String[bound must be greater than origin],\n    BadSize=@String[size must be non-negative],\n    seedUniquifier=@AtomicLong[-3282039941672302964],\n    nextNextGaussian=@Double[0.0],\n    haveNextNextGaussian=@Boolean[false],\n    serialPersistentFields=@ObjectStreamField[][isEmpty=false;size=3],\n    unsafe=@Unsafe[sun.misc.Unsafe@2eaa1027],\n    seedOffset=@Long[24],\n]\n```\n\n- Specify classLoader\n\nNote that the hashcode changes, you need to check the current ClassLoader information first, and extract the hashcode corresponding to the ClassLoader using `sc -d <ClassName>`.\n\nif you use`-c`, you have to manually type hashcode by `-c <hashcode>`.\n\n```bash\n$ getstatic -c 3d4eac69 demo.MathGame random\n```\n\nFor classloader with only one instance, it can be specified by `--classLoaderClass` using class name, which is more convenient to use.\n\n`getstatic --classLoaderClass demo.MathGame random`\n\n- PS: Here the classLoaderClass in java 8 is sun.misc.Launcher$AppClassLoader, while in java 11 it's jdk.internal.loader.ClassLoaders$AppClassLoader. Currently killercoda using java 11.\n\nThe value of `--classloaderclass` is the class name of classloader. It can only work when it matches a unique classloader instance. The purpose is to facilitate the input of general commands. However, `-c <hashcode>` is dynamic.\n\nTip: if the static field is a complex class, you can even use [`OGNL`](https://commons.apache.org/dormant/commons-ognl/language-guide.html) to traverse, filter and access the inner properties of this class.\n\n- [OGNL official guide](https://commons.apache.org/dormant/commons-ognl/language-guide.html)\n- [Special usages](https://github.com/alibaba/arthas/issues/71)\n\nE.g. suppose `n` is a `Map` and its key is a `Enum`, then you can achieve this if you want to pick the key with a specific `Enum` value:\n\n```bash\n$ getstatic com.alibaba.arthas.Test n 'entrySet().iterator.{? #this.key.name()==\"STOP\"}'\nfield: n\n@ArrayList[\n    @Node[STOP=bbb],\n]\nAffect(row-cnt:1) cost in 68 ms.\n\n\n$ getstatic com.alibaba.arthas.Test m 'entrySet().iterator.{? #this.key==\"a\"}'\nfield: m\n@ArrayList[\n    @Node[a=aaa],\n]\n```\n"

    "content": "# Http API\n\n[`Http API` online tutorial](https://arthas.aliyun.com/doc/arthas-tutorials.html?language=en&id=case-http-api)\n\n## Overview\n\nHttp API provides a RESTful-like interactive interface, and both\nrequests and responses data in JSON format. Compared with\nTelnet/WebConsole's output unstructured text data, Http API can provide\nstructured data and support more complex interactive functions, such as\na series of diagnostic operations in specific application scenarios.\n\n### Access address\n\nThe Http API address is: `http://ip:port/api`, the request parameters\nmust be submitted using `POST`. Such as POST\n`http://127.0.0.1:8563/api`.\n\nNote: The telnet port `3658` has compatibility issues with the Chrome\nbrowser. It is recommended to use the http port `8563` to access the\nhttp api.\n\n### Request data format\n\n```json\n{\n  \"action\": \"exec\",\n  \"requestId\": \"req112\",\n  \"sessionId\": \"94766d3c-8b39-42d3-8596-98aee3ccbefb\",\n  \"consumerId\": \"955dbd1325334a84972b0f3ac19de4f7_2\",\n  \"command\": \"version\",\n  \"execTimeout\": \"10000\"\n}\n```\n\nRequest data format description:\n\n- `action` : The requested action/behavior, please refer to \"Request\n  Actions\" for optional values.\n- `requestId` : Optional request ID, generated by the client.\n- `sessionId` : Arthas session ID, one-time command does not need to\n  set the session ID.\n- `consumerId` : Arthas consumer ID, used for multi-person sharing\n  sessions.\n- `command` : Arthas command line\n- `execTimeout` : Timeout for executing commands (ms), default value is 30000.\n\nNote: Different actions use different parameters. Set the parameters\naccording to the specific action.\n\n### Request Actions\n\nCurrently supported request actions are as follows:\n\n- `exec` : The command is executed synchronously, and the command\n  results is returned after the command execution end or interrupted.\n- `async_exec` : The command is executed asynchronously, and the\n  scheduling result of the command is returned immediately. The command\n  execution result is obtained through `pull_results` action.\n- `interrupt_job` : To interrupt the foreground command of the session,\n  similar to the function of Telnet `Ctrl + c`.\n- `pull_results` : Get the result of the command executed\n  asynchronously, and execute it repeatedly in http long-polling mode.\n- `init_session` : Create new session.\n- `join_session` : Join the session, used to support multiple people\n  sharing the same Arthas session.\n- `close_session` : Close the session.\n\n### Response status\n\nThe state attribute in the response indicates the request processing\nstate, and its value is as follows:\n\n- `SCHEDULED`: When the command is executed asynchronously, it means that\n  the job has been created, and may not be executed yet or is being\n  executed;\n- `SUCCEEDED`: The request is processed successfully (completed status);\n- `FAILED`: Request processing failed (completed status), usually\n  accompanied by a message explaining the reason;\n- `REFUSED`: The request is rejected (completed status), usually\n  accompanied by a message explaining the reason;\n\n## One-time command\n\nSimilar to executing batch commands, the one-time commands are executed\nsynchronously. No need to create a session, no need to set the\n`sessionId` option.\n\n```json\n{\n  \"action\": \"exec\",\n  \"command\": \"<Arthas command line>\"\n}\n```\n\nFor example, get the Arthas version number:\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"exec\",\n  \"command\":\"version\"\n}\n'\n```\n\nThe response is as follows:\n\n```json\n{\n  \"state\": \"SUCCEEDED\",\n  \"sessionId\": \"ee3bc004-4586-43de-bac0-b69d6db7a869\",\n  \"body\": {\n    \"results\": [\n      {\n        \"type\": \"version\",\n        \"version\": \"3.3.7\",\n        \"jobId\": 5\n      },\n      {\n        \"jobId\": 5,\n        \"statusCode\": 0,\n        \"type\": \"status\"\n      }\n    ],\n    \"timeExpired\": false,\n    \"command\": \"version\",\n    \"jobStatus\": \"TERMINATED\",\n    \"jobId\": 5\n  }\n}\n```\n\nResponse data format description:\n\n- `state`: Request processing status, refer to the description of\n  \"Response Status\".\n- `sessionId `: Arthas session ID, one-time command to automatically\n  create and destroy temporary sessions.\n- `body.jobId`: The job ID of the command, all output results of the\n  same job are the same jobId.\n- `body.jobStatus`: The job status of the command.\n- `body.timeExpired`: Whether the job execution timed out.\n- `body/results`: Command execution results.\n\n**Command result format description**\n\n```json\n[\n  {\n    \"type\": \"version\",\n    \"version\": \"3.3.7\",\n    \"jobId\": 5\n  },\n  {\n    \"jobId\": 5,\n    \"statusCode\": 0,\n    \"type\": \"status\"\n  }\n]\n```\n\n- `type` : The command result type, except for the special ones such as\n  `status`, the others remain the same as the Arthas command name.\n  Please refer to the section\n  \"[Special command results](#special_command_results)\".\n- `jobId` : The job ID of the command.\n- Other fields are the data of each different command.\n\nNote: You can also use a one-time command to execute continuous output\ncommands such as watch/trace, but you can't interrupt the command\nexecution, and there may be hang up for a long time. Please refer to the\nexample in the\n\"[Make watch command output a map object](#change_watch_value_to_map)\"\nsection.\n\nPlease try to deal with it in the following way:\n\n- Set a reasonable `execTimeout` to forcibly interrupt the command\n  execution after the timeout period is reached to avoid a long hang.\n- Use the `-n` parameter to specify a smaller number of executions.\n- Ensure the methods of the command matched can be successfully hit and\n  the `condition-express` is written correctly. If the `watch/trace` does\n  not hit, even if `-n 1` is specified, it will hang and wait until the\n  execution timeout.\n\n## Session interaction\n\nUsers create and manage Arthas sessions, which are suitable for complex\ninteractive processes. The access process is as follows:\n\n- Create a session\n- Join the session (optional)\n- Pull command results\n- Execute a series of commands\n- Interrupt command execution\n- Close the session\n\n### Create session\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"init_session\"\n}\n'\n```\n\nResponse result:\n\n```json\n{\n  \"sessionId\": \"b09f1353-202c-407b-af24-701b744f971e\",\n  \"consumerId\": \"5ae4e5fbab8b4e529ac404f260d4e2d1_1\",\n  \"state\": \"SUCCEEDED\"\n}\n```\n\nThe new session ID is: `b09f1353-202c-407b-af24-701b744f971e`, and\nconsumer ID is: `5ae4e5fbab8b4e529ac404f260d4e2d1_1`.\n\n### Join session\n\nSpecify the session ID to join, and the server will assign a new\nconsumer ID. Multiple consumers can receive the same command results of\ntarget session. This interface is used to support multiple people\nsharing the same session or refreshing the page to retrieve the session\nhistory.\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"join_session\",\n  \"sessionId\" : \"b09f1353-202c-407b-af24-701b744f971e\"\n}\n'\n```\n\nResponse result:\n\n```json\n{\n  \"consumerId\": \"8f7f6ad7bc2d4cb5aa57a530927a95cc_2\",\n  \"sessionId\": \"b09f1353-202c-407b-af24-701b744f971e\",\n  \"state\": \"SUCCEEDED\"\n}\n```\n\nThe new consumer ID is `8f7f6ad7bc2d4cb5aa57a530927a95cc_2 ` .\n\n### Pull command results\n\nThe action of pulling the command result message is `pull_results`.\nPlease use the Http long-polling method to periodically pull the result\nmessages. The consumer's timeout period is 5 minutes. After the timeout,\nyou need to call `join_session` to allocate a new consumer.\n\nEach consumer is allocated a cache queue separately, and the pull order\ndoes not affect the content received by the consumer.\n\nThe request parameters require session ID and consumer ID:\n\n```bash\ncurl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"pull_results\",\n  \"sessionId\" : \"b09f1353-202c-407b-af24-701b744f971e\",\n  \"consumerId\" : \"8f7f6ad7bc2d4cb5aa57a530927a95cc_2\"\n}\n'\n```\n\nUse Bash scripts to regularly pull results messages:\n\n```bash\nwhile true; do curl -Ss -XPOST http://localhost:8563/api -d '\n{\n  \"action\":\"pull_results\",\n  \"sessionId\" : \"2b085b5d-883b-4914-ab35-b2c5c1d5aa2a\",\n  \"consumerId\" : \"8ecb9cb7c7804d5d92e258b23d5245cc_1\"\n}\n' | json_pp; sleep 2; done\n```\n\nNote: The `json_pp` tool formats the output content as pretty json.\n\nThe response content is as follows:\n\n```json\n{\n

If you need to download the bytecode of classes in a specific package directory in bulk, you can refer to the [dump](/en/doc/dump.md) tool for assistance.\n\n- The decompiled code is syntax highlighted for better readability in Arthas console.\n- It is possible that there's grammar error in the decompiled code, but it should not affect your interpretation.\n\n## Options\n\n|                  Name | Specification                                                   |\n| --------------------: | :-------------------------------------------------------------- |\n|       _class-pattern_ | pattern for the class name                                      |\n|                `[c:]` | hashcode of the class loader that loads the class               |\n| `[classLoaderClass:]` | The class name of the ClassLoader that executes the expression. |\n|                 `[E]` | turn on regex match while the default is wildcard match         |\n\n## Usage\n\n### Decompile `java.lang.String`\n\n```java\n$ jad java.lang.String\n\nClassLoader:\n\nLocation:\n\n\n        /*\n         * Decompiled with CFR.\n         */\n        package java.lang;\n\n        import java.io.ObjectStreamField;\n        import java.io.Serializable;\n...\n        public final class String\n        implements Serializable,\n        Comparable<String>,\n        CharSequence {\n            private final char[] value;\n            private int hash;\n            private static final long serialVersionUID = -6849794470754667710L;\n            private static final ObjectStreamField[] serialPersistentFields = new ObjectStreamField[0];\n            public static final Comparator<String> CASE_INSENSITIVE_ORDER = new CaseInsensitiveComparator();\n...\n            public String(byte[] byArray, int n, int n2, Charset charset) {\n/*460*/         if (charset == null) {\n                    throw new NullPointerException(\"charset\");\n                }\n/*462*/         String.checkBounds(byArray, n, n2);\n/*463*/         this.value = StringCoding.decode(charset, byArray, n, n2);\n            }\n...\n```\n\n### Print source only\n\nBy default, the decompile result will have the `ClassLoader` information. With the `--source-only` option, you can print only the source code. Conveniently used with the [mc](mc.md)/[retransform](retransform.md) commands.\n\n```java\n$ jad --source-only demo.MathGame\n/*\n * Decompiled with CFR 0_132.\n */\npackage demo;\n\nimport java.io.PrintStream;\nimport java.util.ArrayList;\nimport java.util.Iterator;\nimport java.util.List;\nimport java.util.Random;\nimport java.util.concurrent.TimeUnit;\n\npublic class MathGame {\n    private static Random random = new Random();\n    public int illegalArgumentCount = 0;\n...\n```\n\n### Decompile the specified method\n\n```java\n$ jad demo.MathGame main\n\nClassLoader:\n+-sun.misc.Launcher$AppClassLoader@232204a1\n  +-sun.misc.Launcher$ExtClassLoader@7f31245a\n\nLocation:\n/private/tmp/math-game.jar\n\n       public static void main(String[] args) throws InterruptedException {\n           MathGame game = new MathGame();\n           while (true) {\n/*16*/         game.run();\n/*17*/         TimeUnit.SECONDS.sleep(1L);\n           }\n       }\n```\n\n### Do not print line numbers\n\n- `--lineNumber`: Output source code contins line numbers, default value true\n\n```java\n$ jad demo.MathGame main --lineNumber false\n\nClassLoader:\n+-sun.misc.Launcher$AppClassLoader@232204a1\n  +-sun.misc.Launcher$ExtClassLoader@7f31245a\n\nLocation:\n/private/tmp/math-game.jar\n\npublic static void main(String[] args) throws InterruptedException {\n    MathGame game = new MathGame();\n    while (true) {\n        game.run();\n        TimeUnit.SECONDS.sleep(1L);\n    }\n}\n```\n\n### Decompile with specified classLoader\n\n::: tip\nIf the target class is loaded by multiple classloaders, `jad` outputs the `hashcode` of the corresponding classloaders, then you can re-run `jad` and specify `-c <hashcode>` to decompile the target class from the specified classloader.\n:::\n\n```java\n$ jad org.apache.log4j.Logger\n\nFound more than one class for: org.apache.log4j.Logger, Please use jad -c hashcode org.apache.log4j.Logger\nHASHCODE  CLASSLOADER\n69dcaba4  +-monitor's ModuleClassLoader\n6e51ad67  +-java.net.URLClassLoader@6e51ad67\n            +-sun.misc.Launcher$AppClassLoader@6951a712\n            +-sun.misc.Launcher$ExtClassLoader@6fafc4c2\n2bdd9114  +-pandora-qos-service's ModuleClassLoader\n4c0df5f8  +-pandora-framework's ModuleClassLoader\n\nAffect(row-cnt:0) cost in 38 ms.\n$ jad org.apache.log4j.Logger -c 69dcaba4\n\nClassLoader:\n+-monitor's ModuleClassLoader\n\nLocation:\n/Users/admin/app/log4j-1.2.14.jar\n\npackage org.apache.log4j;\n\nimport org.apache.log4j.spi.*;\n\npublic class Logger extends Category\n{\n    private static final String FQCN;\n\n    protected Logger(String name)\n    {\n        super(name);\n    }\n\n...\n\nAffect(row-cnt:1) cost in 190 ms.\n```\n\nFor classloader with only one instance, it can be specified by `--classLoaderClass` using class name, which is more convenient to use.\n\nThe value of `--classloaderclass` is the class name of classloader. It can only work when it matches a unique classloader instance. The purpose is to facilitate the input of general commands. However, `-c <hashcode>` is dynamic.\n\n### Decompile with specified directory for dumpping class\n\nDecompile class with `jad` need to dump corresponding classes into files. The default directory for dumpping classes is the directory of log file specified in logback.xml, we can use `-d/--directory` to specify the directory for dummping class.\n\n```java\n$ jad demo.MathGame -d /tmp/jad/dump\n```\n"

It is integrated into the Java Virtual Machine (JVM) and causes almost no performance overhead, so it can be used even in heavily loaded production environments.\n:::\n\nThe `jfr` command supports starting and stopping JFR recordings during dynamic program running. Recording collects data about _events_. Events occur in the JVM or the Java application at a specific point in time. Each event has a name, a time stamp, and an optional _payload_. The payload is the data associated with an event, for example, the CPU usage, the Java heap size before and after the event, the thread ID of the lock holder, and so on.\n\nThe basic usage of the `jfr` command is`jfr cmd [actionArg]`\n\n> Note: jfr is supported only after the 8u262 version of jdk8\n\n### Supported Options\n\n|          Name | Specification                                                                                |\n| ------------: | :------------------------------------------------------------------------------------------- |\n|         _cmd_ | Command to execute, support【start，status，dump，stop】                                     |\n|   _actionArg_ | Attribute name pattern                                                                       |\n|          [n:] | Name of recording                                                                            |\n|          [r:] | Recording id                                                                                 |\n| [dumponexit:] | When the program exits, whether to dump the .jfr file.

To achieve this, copy the default configuration first,\n\n```\n\"\\C-a\": beginning-of-line\n\"\\C-e\": end-of-line\n\"\\C-f\": forward-word\n\"\\C-b\": backward-word\n\"\\e[D\": backward-char\n\"\\e[C\": forward-char\n\"\\e[B\": next-history\n\"\\e[A\": previous-history\n\"\\C-h\": backward-delete-char\n\"\\C-?\": backward-delete-char\n\"\\C-u\": undo\n\"\\C-d\": delete-char\n\"\\C-k\": kill-line\n\"\\C-i\": complete\n\"\\C-j\": accept-line\n\"\\C-m\": accept-line\n\"\\C-w\": backward-delete-word\n\"\\C-x\\e[3~\": backward-kill-line\n\"\\e\\C-?\": backward-kill-word\n```\n\nthen replace `\"\\C-h\": backward-delete-char` with `\"\\C-h\": backward-char`, then reconnect to Arthas console to take effect.\n\n## Shortcuts for jobs\n\n- `ctrl + c`: Terminates current command\n- `ctrl + z`: Suspends the current command, you can restore this command with `bg`/`fg`, or `kill` it.\n- `ctrl + a`: Go to the beginning the line\n- `ctrl + e`: Go to the end of the line\n"

[APPLICATION]\n```\n\nFor classloader with only one instance, it can be specified by `--classLoaderClass` using class name, which is more convenient to use.\n\n`logger --classLoaderClass sun.misc.Launcher$AppClassLoader`\n\n- PS: Here the classLoaderClass in java 8 is sun.misc.Launcher$AppClassLoader, while in java 11 it's jdk.internal.loader.ClassLoaders$AppClassLoader.\n\nThe value of `--classloaderclass` is the class name of classloader. It can only work when it matches a unique classloader instance. The purpose is to facilitate the input of general commands. However, `-c <hashcode>` is dynamic.\n\n### Update logger level\n\n```bash\n[arthas@2062]$ logger --name ROOT --level debug\nupdate logger level success.\n```\n\n### Speecify classloader to update logger level\n\nBy default，logger command will be executed under SystemClassloader, if the application is a traditional `war`, or using spring boot fat jar, then it needs to specify classloader。\n\nYou can first use `sc -d yourClassName` to check specified classloader hashcode，then specify classloader when updating logger level:\n\n```bash\n[arthas@2062]$ logger -c 2a139a55 --name ROOT --level debug\n```\n\n### View the logger information without appenders\n\nBy default, the `logger` command only prints information about the logger with appenders. If you want to see information about loggers without `appender`, you can use the parameter `--include-no-appender`.\n\nNote that the output will usually be very long.\n\n```bash\n[arthas@2062]$ logger --include-no-appender\n name                                   ROOT\n class                                  ch.qos.logback.classic.Logger\n classLoader                            sun.misc.Launcher$AppClassLoader@2a139a55\n classLoaderHash                        2a139a55\n level                                  DEBUG\n effectiveLevel                         DEBUG\n additivity                             true\n codeSource                             file:/Users/hengyunabc/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar\n appenders                              name            CONSOLE\n                                        class           ch.qos.logback.core.ConsoleAppender\n                                        classLoader     sun.misc.Launcher$AppClassLoader@2a139a55\n                                        classLoaderHash 2a139a55\n                                        target          System.out\n                                        name            APPLICATION\n                                        class           ch.qos.logback.core.rolling.RollingFileAppender\n                                        classLoader     sun.misc.Launcher$AppClassLoader@2a139a55\n                                        classLoaderHash 2a139a55\n                                        file            app.log\n                                        name            ASYNC\n                                        class           ch.qos.logback.classic.AsyncAppender\n                                        classLoader     sun.misc.Launcher$AppClassLoader@2a139a55\n                                        classLoaderHash 2a139a55\n                                        appenderRef     [APPLICATION]\n\n name                                   com\n class                                  ch.qos.logback.classic.Logger\n classLoader                            sun.misc.Launcher$AppClassLoader@2a139a55\n classLoaderHash                        2a139a55\n level                                  null\n effectiveLevel                         DEBUG\n additivity                             true\n codeSource                             file:/Users/hengyunabc/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar\n\n name                                   com.alibaba\n class                                  ch.qos.logback.classic.Logger\n classLoader                            sun.misc.Launcher$AppClassLoader@2a139a55\n classLoaderHash                        2a139a55\n level                                  null\n effectiveLevel                         DEBUG\n additivity                             true\n codeSource                             file:/Users/hengyunabc/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar\n...\n```\n"

    "content": "# Manually Install Arthas\n\n1. Download the latest version\n\n   **Latest version, Click To Download**: [![](https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square \"Arthas\")](https://arthas.aliyun.com/download/latest_version)\n\n2. Unzip zip file\n\n   ```bash\n   unzip arthas-packaging-bin.zip\n   ```\n\n3. Install Arthas\n\n   It is recommended to completely remove all old versions of Arthas before installation.\n\n   ```bash\n   sudo su admin\n   rm -rf /home/admin/.arthas/lib/* # remove all the leftover of the old outdated Arthas\n   cd arthas\n   ./install-local.sh # switch the user based on the owner of the target Java process.\n   ```\n\n4. Start Arthas\n\n   Make sure `stop` the old Arthas server before start.\n\n   ```bash\n   ./as.sh\n   ```\n\n## Startup with as.sh/as.bat\n\n### Linux/Unix/Mac\n\nYou can install Arthas with one single line command on Linux, Unix, and Mac. Pls. copy the following command and paste it into the command line, then press _Enter_ to run:\n\n```bash\ncurl -L https://arthas.aliyun.com/install.sh | sh\n```\n\nThe command above will download the bootstrap script `as.sh` to the current directory. You can move it the any other place you want, or put its location in `$PATH`.\n\nYou can enter its interactive interface by executing `as.sh`, or execute `as.sh -h` for more help information.\n\n### Windows\n\nLatest Version, Click To Download: [![](https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square \"Arthas\")](https://arthas.aliyun.com/download/latest_version)\n\nDownload and unzip, then find `as.bat` from 'bin' directory. For now this script will only take one argument `pid`, which means you can only diagnose the local Java process. (Welcome any bat script expert to make it better :heart:)\n\n```bash\nas.bat <pid>\n```\n\nIf you want to diagnose Java process run as windows service, try these commands:\n\n```bash\nas-service.bat -port <port>\nas-service.bat -pid <pid>\nas-service.bat -pid <pid> --interact\n```\n\nUse this command to remove arthas service:\n\n```bash\nas-service.bat -remove\n```\n\n## Manual command line startup\n\nIf you fail to boot Arthas with the provided batch file, you could try to assemble the bootstrap command in the following way.\n\n1. Locate java in the target JVM:\n   - Linux/Unix/Mac: `ps aux | grep java`\n   - Windows: open the Process Monitor to search java\n\n2. Assemble bootstrap command:\n\n   Let's suppose we are using `/opt/jdk1.8/bin/java`, then the command should be:\n\n   ```bash\n   /opt/jdk1.8/bin/java -Xbootclasspath/a:/opt/jdk1.8/lib/tools.jar \\\n       -jar /tmp/arthas-packaging/arthas-core.jar \\\n       -pid 15146 \\\n       -target-ip 127.0.0.1 -telnet-port 3658 -http-port 8563 \\\n       -core /tmp/arthas-packaging/arthas-core.jar \\\n       -agent /tmp/arthas-packaging/arthas/arthas-agent.jar\n   ```\n\n   Note:\n   - `-Xbootclasspath` adds tools.jar\n   - `-jar /tmp/arthas-packaging/arthas-core.jar` specifies main entry\n   - `-pid 15146` specifies the target java process PID\n   - `-target-ip 127.0.0.1` specifies the IP\n   - `-telnet-port 3658 -http-port 8563` specifies telnet and HTTP ports for remote access\n   - `-core /tmp/arthas-packaging/arthas-core.jar -agent /tmp/arthas-packaging/arthas/arthas-agent.jar` specifies core/agent jar package\n\n   If you are running on JDK 1.9 or above，then it's unnecessary to add `tools.jar` in option `-Xbootclasspath`.\n\n   You can find the logs from `~/logs/arthas/arthas.log`.\n\n3. Use telnet to connect once attaching to the target JVM (in step 2) succeeds\n\n   ```bash\n   telnet 127.0.0.1 3658\n   ```\n"

Start Application\n\nStart Arthas or Java application with Arthas normally. By default, MCP service will be exposed on HTTP port 8563.\n\nVerify MCP service is running:\n\n```bash\ncurl http://localhost:8563/mcp\n```\n\nIf MCP protocol information is returned, the service has started successfully.\n\n### 3. Configure AI Client\n\nConfiguration examples for mainstream AI clients:\n\n#### Cherry Studio / Cline\n\nAdd MCP server configuration in settings:\n\n```json\n{\n  \"mcpServers\": {\n    \"arthas-mcp\": {\n      \"type\": \"streamableHttp\",\n      \"url\": \"http://localhost:8563/mcp\"\n    }\n  }\n}\n```\n\n## Configuration\n\n### Arthas Configuration\n\n| Property             | Description                                                                 | Default                              |\n| -------------------- | --------------------------------------------------------------------------- | ------------------------------------ |\n| `arthas.mcpEndpoint` | MCP service access path                                                     | None (requires manual configuration) |\n| `arthas.mcpProtocol` | Transport protocol mode: `STREAMABLE` (stateful) or `STATELESS` (stateless) | `STREAMABLE`                         |\n| `arthas.httpPort`    | HTTP service port                                                           | 8563                                 |\n| `arthas.password`    | Authentication password (when authentication enabled)                       | None                                 |\n\n### Transport Protocol Mode\n\nArthas MCP Server supports two transport protocol modes:\n\n- **STREAMABLE mode** (default): Stateful mode, maintains persistent connections via HTTP/SSE, supports long-running commands (e.g. watch, trace, monitor and other streaming tools), progress notifications, and session state. Suitable for interactive diagnostic scenarios.\n- **STATELESS mode**: Stateless mode, each request is independent. Suitable for simple one-off query scenarios.\n\nConfigure in `arthas.properties`:\n\n```properties\narthas.mcpEndpoint=/mcp\n# Optional, defaults to STREAMABLE\narthas.mcpProtocol=STREAMABLE\n```\n\n### Authentication Configuration\n\nWhen `arthas.password` is configured in the configuration file, MCP Server will automatically enable authentication. In this case, you need to add an authentication header in the AI client configuration, with the Bearer Token set to the configured password value.\n\nConfiguration file example (`arthas.properties`):\n\n```properties\narthas.password=your-secure-password\n```\n\nAI client configuration example:\n\n```json\n{\n  \"mcpServers\": {\n    \"arthas-mcp\": {\n      \"type\": \"streamableHttp\",\n      \"url\": \"http://localhost:8563/mcp\",\n      \"headers\": {\n        \"Authorization\": \"Bearer your-secure-password\"\n      }\n    }\n  }\n}\n```\n\n::: warning\n**Note**: The token in the Authorization header must exactly match the value configured in `arthas.password`.\n:::\n\n### viewfile Directory Whitelist Configuration\n\nThe `viewfile` tool by default only allows viewing files in the following directories:\n\n- The `arthas-output` directory under the current working directory (if it exists)\n- The `~/logs/` directory under the user's home directory (if it exists)\n\nAdditional directories can be configured via environment variable:\n\n```bash\nexport ARTHAS_MCP_VIEWFILE_ALLOWED_DIRS=/path/to/dir1,/path/to/dir2\n```\n\n## Feedback & Contribution\n\n::: tip\nArthas MCP Server is an experimental feature.

Furthermore, Arthas is designed to have no side effect to the business logic.\n\n## Items to monitor\n\n|      Item | Specification                            |\n| --------: | :--------------------------------------- |\n| timestamp | timestamp                                |\n|     class | Java class                               |\n|    method | method (constructor and regular methods) |\n|     total | calling times                            |\n|   success | success count                            |\n|      fail | failure count                            |\n|        rt | average RT                               |\n| fail-rate | failure ratio                            |\n\n## Parameters\n\nParameter `[c:]` stands for cycles of statistics.

When set `json-format` to true, commands like `wathc`/`tt` will print result with `json` format.\n:::\n\n## Set special option value\n\nFor example, to enable saving command execution result, input the command below:\n\n```\n$ options save-result true\n NAME         BEFORE-VALUE  AFTER-VALUE\n----------------------------------------\n save-result  false         true\n```\n\n## Set `unsafe` to true to enhance the classes under the `java.*` package\n\nBy default, `watch`/`trace`/`tt`/`trace`/`monitor` command do not support classes under `java.*` package. You can set `unsafe` to true to enhance the classes under the `java.*` package.\n\n```bash\n$ options unsafe true\n NAME    BEFORE-VALUE  AFTER-VALUE\n-----------------------------------\n unsafe  false         true\n```\n\n```bash\n$ watch java.lang.invoke.Invokers callSiteForm\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 61 ms, listenerId: 1\n```\n\n## Turn off strict mode, allow setting object properties in ognl expressions\n\n::: tip\nsince 3.6.0\n:::\n\nFor new users, there may be misuses when writing ognl expressions.\n\nFor example, for `Student`, when judging the age is equal to 18, the conditional expression may be mistakenly written as `target.age=18`, which actually sets the `age` of the current object to 18. The correct spelling is `target.age==18`.\n\nIn order to prevent misuse like the above, Arthas enables `strict` mode by default, in `ognl` expressions, it is forbidden to update the property of the object or call the `setter` method.\n\nTake `MathGame` as an example, the following error message will appear.\n\n```\n$ watch demo.MathGame primeFactors 'target' 'target.illegalArgumentCount=1'\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 206 ms, listenerId: 1\nwatch failed, condition is: target.illegalArgumentCount=1, express is: target, By default, strict mode is true, not allowed to set object properties. Want to set object properties, execute `options strict false`, visit /Users/admin/logs/arthas/arthas.log for more details.\n```\n\nIf the user want to change the object properties in the `ognl` expression, you can execute `options strict false` to turn off the `strict` mode.\n\n- For more information, please refer to: https://github.com/alibaba/arthas/issues/2128\n"

    "content": "# profiler\n\n[`profiler` online tutorial](https://arthas.aliyun.com/doc/arthas-tutorials.html?language=en&id=command-profiler)\n\n::: tip\nGenerate a flame graph using [async-profiler](https://github.com/jvm-profiling-tools/async-profiler)\n:::\n\nThe `profiler` command supports generating flame graph for application hotspots.\n\nThe basic usage of the `profiler` command is `profiler action [actionArg]`\n\nThe arguments of `profiler` command basically keeps consistent with upstream project [async-profiler](https://github.com/async-profiler/async-profiler), you can refer to its README, Github Discussions and other documentations for further information of usage.\n\n## Supported Options\n\n|        Name | Specification                                                                    |\n| ----------: | :------------------------------------------------------------------------------- |\n|    _action_ | Action to execute                                                                |\n| _actionArg_ | Attribute name pattern                                                           |\n|        [i:] | sampling interval in ns (default: 10'000'000, i.e. 10 ms)                        |\n|        [f:] | dump output to specified directory                                               |\n|        [d:] | run profiling for specified seconds                                              |\n|        [e:] | which event to trace (cpu, alloc, lock, cache-misses etc.), default value is cpu |\n\n## Start profiler\n\n```\n$ profiler start\nStarted [cpu] profiling\n```\n\n::: tip\nBy default, the sample event is `cpu`. Other valid profiling modes can be specified with the `--event` parameter, see relevant contents below.\n:::\n\n## Get the number of samples collected\n\n```\n$ profiler getSamples\n23\n```\n\n## View profiling status\n\n```bash\n$ profiler status\n[cpu] profiling is running for 4 seconds\n```\n\nCan view which `event` and sampling time.\n\n## View profiler memory usage\n\n```\n$ profiler meminfo\nCall trace storage:   10244 KB\n      Dictionaries:      72 KB\n        Code cache:   12890 KB\n------------------------------\n             Total:   23206 KB\n```\n\n## Stop profiler\n\n### Generating flame graph results\n\nBy default, the result file is `html` file in [Flame Graph](https://github.com/BrendanGregg/FlameGraph) format. You can also specify other format with the `-o` or `--format` parameter, including flat, traces, collapsed, flamegraph, tree, jfr, md:\n\n### Generate LLM-friendly Markdown report\n\nWhen `--format md` (or `md=N`) is specified, Arthas generates a structured Markdown report based on async-profiler `collapsed` output, which is easy to copy/paste to an LLM or grep in terminal. The report includes:\n\n- Top N Hotspots (self)\n- Call Tree (truncated by samples)\n- Function Details (top stacks per hotspot)\n\n```bash\n$ profiler stop --format md\n```\n\nWrite to file (optional):\n\n```bash\n$ profiler stop --format md --file /tmp/profile.md\n```\n\nIf `--file` ends with `.md` and `--format` is not specified, Arthas will infer Markdown output automatically:\n\n```bash\n$ profiler stop --file /tmp/profile.md\n```\n\nSet TopN (optional, default 10):\n\n```bash\n$ profiler stop --format md=20\n```\n\n```bash\n$ profiler stop --format flamegraph\nprofiler output file: /tmp/test/arthas-output/20211207-111550.html\nOK\n```\n\nWhen extension of filename in `--file` parameter is `html` or `jfr`, the output format can be infered. For example, `--file /tmp/result.html` will generate flamegraph automatically.\n\n## View profiler results under arthas-output via browser\n\nBy default, arthas uses port 3658, which can be opened: [http://localhost:3658/arthas-output/](http://localhost:3658/arthas-output/) View the `arthas-output` directory below Profiler results:\n\n![](/images/arthas-output.jpg)\n\nClick to view specific results:\n\n![](/images/arthas-output-svg.jpg)\n\n::: tip\nIf using the chrome browser, may need to be refreshed multiple times.\n:::\n\n## Profiler supported events\n\nUnder different platforms and different OSs, the supported events are different. For example, under macos:\n\n```bash\n$ profiler list\nBasic events:\n  cpu\n  alloc\n  lock\n  wall\n  itimer\n  ctimer\n```\n\nUnder linux\n\n```bash\n$ profiler list\nBasic events:\n  cpu\n  alloc\n  lock\n  wall\n  itimer\n  ctimer\nJava method calls:\n  ClassName.methodName\nPerf events:\n  page-faults\n  context-switches\n  cycles\n  instructions\n  cache-references\n  cache-misses\n  branch-instructions\n  branch-misses\n  bus-cycles\n  L1-dcache-load-misses\n  LLC-load-misses\n  dTLB-load-misses\n  rNNN\n  pmu/event-descriptor/\n  mem:breakpoint\n  trace:tracepoint\n  kprobe:func\n  uprobe:path\n```\n\nIf you encounter the permissions/configuration issues of the OS itself and then missing some events, you can refer to the [async-profiler](https://github.com/jvm-profiling-tools/async-profiler) documentation.\n\nYou can use `check` action to check if a profiling event is available, this action receives the same format options with `start`.\n\nYou can use the `--event` parameter to specify the event to sample, for example, `alloc` event means heap memory allocation profiling:\n\n```bash\n$ profiler start --event alloc\n```\n\n## Resume sampling\n\n```bash\n$ profiler resume\nStarted [cpu] profiling\n```\n\nThe difference between `start` and `resume` is: `start` will clean existing result of last profiling before starting, `resume` will retain the existing result and add result of this time to it.\n\nYou can verify the number of samples by executing `profiler getSamples`.\n\n## Dump action\n\n```bash\n$ profiler dump\nOK\n```\n\nThe `dump` action saves profiling result to default file or specified file, but profiling will continue. That means if you start profiling and dump after 5 seconds, then dump after 2 seconds again, you will get 2 result files, the first one contains profiling result of 0\\~5 seconds and the second one contains that of 0\\~7 seconds.\n\n## Use `execute` action to execute complex commands\n\nFor example, start sampling:\n\n```bash\nprofiler execute 'start,framebuf=5000000'\n```\n\nStop sampling and save to the specified file:\n\n```bash\nprofiler execute 'stop,file=/tmp/result.html'\n```\n\nSpecific format reference: [arguments.cpp](https://github.com/async-profiler/async-profiler/blob/v2.9/src/arguments.cpp#L52)\n\n## View all supported actions\n\n```bash\n$ profiler actions\nSupported Actions: [resume, dumpCollapsed, getSamples, start, list, version, execute, meminfo, stop, load, dumpFlat, dump, actions, dumpTraces, status, check]\n```\n\n## View version\n\n```bash\n$ profiler version\nAsync-profiler 2.9 built on May  8 2023\nCopyright 2016-2021 Andrei Pangin\n```\n\n## Configure Java stack depth\n\nYou can use `-j` or `--jstackdepth` option to configure maximum Java stack depth. This option will be ignored if value is greater than default 2048. This option is useful when you don't want to see stacks that are too deep. Below is usage example:\n\n```bash\nprofiler start -j 256\n```\n\n## Profiling different threads separately\n\nYou can use `-t` or `--threads` flag option to profile different threads separately, each stack trace will end with a frame that denotes a single thread.\n\n```bash\nprofiler start -t\n```\n\n## Configure include/exclude to filter data\n\nIf the application is complex and generates a lot of content, and you want to focus on only part of stack traces, you can filter stack traces by `--include/--exclude`. `--include` defines the name pattern that must be present in the stack traces, while `--exclude` is the pattern that must not occur in any of stack traces in the output.A pattern may begin or end with a star `*` that denotes any (possibly empty) sequence of characters. such as\n\n```bash\nprofiler stop --include'java/*' --include 'com/demo/*' --exclude'*Unsafe.park*'\n```\n\n> Both `--include/--exclude` support being set multiple times, but need to be configured at the end of the command line. You can also use short parameter format `-I/-X`.\n> Note that `--include/--exclude` only supports configuration at `stop` action or `start` action with `-d`/`--duration` parameter, otherwise it will not take effect.\n\n## Specify execution time\n\nFor example, if you want the profiler to automatically end after 300 seconds, you can specify it with the `-d`/`--duration` parameter in start action:\n\n```bash\nprofiler start --duration 300\n```\n\n## Generate jfr format result\n\n> Note that jfr only supports configuration at `start`. If it is specified at `stop`, it will not take effect.\n\n```\nprofiler start --file /tmp/test.jfr\nprofiler start -o jfr\n```\n\nThe `file` parameter supports some variables:\n\n- Timestamp: `--file /tmp/test-%t.jfr`\n- Process ID: `--file /tmp/test-%p.jfr`\n\nThe generated results can be viewed with tools that support the jfr format. such as:\n\n- JDK Mission Control: https://github.com/openjdk/jmc\n- JProfiler: https://github.com/alibaba/arthas/issues/1416\n\n## Control details in result\n\nThe `-s` parameter will use simple name instead of Fully qualified name, e.g. `MathGame.main` instead of `demo.MathGame.main`. The `-g` parameter will use method signatures instead of method names, e.g. `demo.MathGame.main([Ljava/lang/String;)V` instead of `demo.MathGame.main`. There are many parameters related to result format details, you can refer to [async-profiler README](https://github.com/async-profiler/async-profiler#readme) and [async-profiler Github Discussions](https://github.com/async-profiler/async-profiler/discussions) and other information.\n\nFor example, in command below, `-s` use simple name for Java class, `-g` show method signatures, `-a` will annotate Java methods, `-l` will prepend library names for native method, `--title` specify a title for flame graph page, `--minwidth` will skip frames smaller than 15% in flame graph, `--reverse` will generate stack-reversed FlameGraph / Call tree.\n\n```\nprofiler stop -s -g -a -l --title <flametitle> --minwidth 15 --reverse\n```\n\n## The 'unknown' in profiler result\n\n- https://github.com/jvm-profiling-tools/async-profiler/discussions/409\n\n## Config locks/allocations profiling threshold\n\nWhen profiling in locks or allocations event, you can use `--lock` or `--alloc` to config thresholds, for example:\n\n```bash\nprofiler start -e lock --lock 10ms\nprofiler start -e alloc --alloc 2m\n```\n\nwill profile contended locks longer than 10ms (default unit is ns if no unit is specified), or profile allocations with 2m BYTES interval.\n\n## Config JFR chunks\n\nWhen using JFR as output format, you can use `--chunksize` or `--chunktime` to config approximate size (in bytes, default value is 100MB) and time limits (default value is 1 hour) for a single JFR chunk. For example:\n\n```bash\nprofiler start -f profile.jfr --chunksize 100m --chunktime 1h\n```\n\n## Group threads by scheduling policy\n\nYou can use `--sched` flag option to group threads in output by Linux-specific scheduling policy: BATCH/IDLE/OTHER, for example:\n\n```bash\nprofiler start --sched\n```\n\nThe second line from bottom in flamegraph represent the scheduling policy.\n\n## Build allocation profile from live objects only\n\nUse `--live` flag option to retain allocation samples with live objects only (object that have not been collected by the end of profiling session). Useful for finding Java heap memory leaks.\n\n```bash\nprofiler start --live\n```\n\n## Config method of collecting C stack frames\n\nUse `--cstack MODE` to config how to walk native frames (C stack). Possible modes are fp (Frame Pointer), dwarf (DWARF unwind info), lbr (Last Branch Record, available on Haswell since Linux 4.1), and no (do not collect C stack).\n\nBy default, C stack is shown in cpu, itimer, wall-clock and perf-events profiles. Java-level events like alloc and lock collect only Java stack.\n\n```bash\nprofiler --cstack fp\n```\n\nThe command above will collection Frame Pointer of C stacks.\n\n## Start/Stop Profiling When a Specified Native Function is Executed\n\nUsing the `--begin function` and `--end function` options, you can start or stop profiling when a specified native function is executed. The main use is to analyze specific JVM phases, such as GC and Safepoint. You need to use the native function names in the specific JVM implementation, such as SafepointSynchronize::begin and SafepointSynchronize::end in HotSpot JVM.\n\n### Time-to-Safepoint Profiling\n\nThe option `--ttsp` is actually an alias for `--begin SafepointSynchronize::begin --end RuntimeService::record_safepoint_synchronized`. It is a constraint, not a separate event type. The Profiler will work regardless of which event is selected, but only events between VM operations and Safepoint requests will be recorded.\n\n`profiler` now automatically includes profiler.Window events in the generated JFR file when the `--ttsp` option is used and a JFR output format is specified. These events represent the time interval of each Time-to-Safepoint pause, allowing you to analyze these pauses without relying on JVM logs.\n\nExample\n\n```bash\nprofiler start --begin SafepointSynchronize::begin --end RuntimeService::record_safepoint_synchronized\nprofiler start --ttsp --format jfr\n```\n\nThe generated JFR file will contain profiler.Window events, which can be viewed and analyzed using tools such as JDK Mission Control.\n\n**Notes:**\n\n- profiler.Window events are generic events that apply to any time window using the --begin and --end triggers, not just Safepoint pauses.\n\n- When analyzing long Safepoint pauses, profiler.Window events can help you identify the cause of delays.\n\n- When using the --ttsp option, make sure to use the JFR output format so that profiler.Window events can be generated and viewed.\n\n## Generate JFR file using events recorded by profiler\n\nUse `--jfrsync CONFIG` option to specify configuration to start Java Flight Recording. The output jfr file will contain all normal JFR events, but the sampling sources are provided by the profiler.\n\nCONFIG parameters:\n\n- Preset configuration: CONFIG can be profile, which means to use the preset profile configuration in the $JAVA_HOME/lib/jfr directory.\n\n- Custom configuration file: CONFIG can also be a custom JFR configuration file (.jfc). The value of this option uses the same format as the settings option of the jcmd JFR.start command.\n\n- Specify a list of JFR events: Now, you can directly specify the list of JFR events to be enabled in --jfrsync without creating a .jfc file. To specify a list of events, start with + and separate multiple events with +.\n\nExample:\n\nStart JFR with a preset profile configuration:\n\n```bash\nprofiler start -e cpu --jfrsync profile -f combined.jfr\n```\n\nDirectly specify a list of JFR events, for example, to enable jdk.YoungGarbageCollection and jdk.OldGarbageCollection events:\n\n```bash\nprofiler start -e cpu --jfrsync +jdk.YoungGarbageCollection+jdk.OldGarbageCollection -f combined.jfr\n```\n\n**Notes**\n\n- When specifying a list of events, events are separated by a plus sign + because commas , are used to separate different options.\n- If the --jfrsync parameter does not start with +, it is treated as a preset profile name or a path to a .jfc configuration file.\n- Directly specifying a list of events is particularly useful when the target application is running in a container, without additional file operations.\n\n## Run profiler in a loop\n\nUse `--loop TIME` to run profiler in a loop (continuous profiling). The argument is either a clock time (hh:mm:ss) or a loop duration in seconds, minutes, hours, or days. Make sure the filename includes a timestamp pattern, or the output will be overwritten on each iteration. The command below will run profiling endlessly and save records of each hour to a jfr file.\n\n> If the `-f` parameter is not specified, nothing will be saved. If the `-f` parameter does not contain `%t`, it will overwrite the same file repeatedly.\n\n```bash\nprofiler start --loop 1h -f /var/log/profile-%t.jfr\n```\n\n## `--timeout` option\n\n```bash\nprofiler start --timeout 300s\n```\n\nThis option specifies the time when profiling will automatically stop. The format is the same as in loop: it is either a wall clock time (12:34:56) or a relative time interval (2h).\n\nBoth `--loop` and `--timeout` are used for `start` action, for further information refer to [async-profiler docs](https://github.com/async-profiler/async-profiler/blob/master/docs/ProfilerOptions.md).\n\n## `--wall` option\n\nThe -- wall option allows for simultaneous performance analysis of both CPU and Wall Clock. This joint analysis helps to more comprehensively identify and understand performance bottlenecks in applications.\n--The wall option allows users to set the sampling interval for Wall Clock analysis independently of CPU analysis. For example, by setting - e cpu-i 10-- wall 200, the CPU sampling interval can be set to 10 milliseconds, and the wall clock sampling interval can be set to 200 milliseconds.\nWhen conducting joint CPU and Wall Clock analysis, the output format must be set to jfr. This format supports recording the state information of threads (such as State_SUNNABLE or State_SLEEPING) to distinguish between different types of sampling events.\n\ninfluence\nLinux platform: This new feature is only available on the Linux platform. The CPU analysis engine on macOS is already based on Wall clock mode, so there are no additional benefits.\nPerformance overhead: Enabling Wall clock analysis will increase performance overhead, so when analyzing both CPU and Wall clock simultaneously, it is recommended to increase the interval between Wall clocks.\n\n```bash\nprofiler start -e cpu -i 10 --wall 100 -f out.jfr\n```\n\n## `ctimer` events\n\n`ctimer` events are a new CPU sampling mode based on `timer_create`, providing accurate CPU sampling without `perf_events`.\n\nIn some cases, `perf_events` may not be available, for example due to `perf_event_paranoid` settings or `seccomp` restrictions, or in container environments. Although itimer events can work in containers, there may be sampling inaccuracies.\n\n`ctimer` events combine the advantages of `cpu` and `itimer`:\n\n- High accuracy: provides accurate CPU sampling.\n\n- Container-friendly: available in containers by default.\n\n- Low resource consumption: does not consume file descriptors.\n\n**Note that `ctimer` events are currently only supported on `Linux`, not `macOS`. **\nSee [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/855) for more information.\n\nExample:\n\n```bash\nprofiler start -e ctimer -o jfr -f ./out-test.jfr\n```\n\n## `vtable` Feature\n\nIn some applications, a lot of CPU time is spent in calling `megamorphic` virtual or interface methods, which is shown as `vtable stub` or `itable stub` in performance analysis. This does not help us understand why a specific call site is `megamorphic` and how to optimize it.\n\nThe vtable feature can add a pseudo frame on top of the `vtable stub` or `itable stub`, showing the actual object type being called. This helps to clearly understand the ratio of different receivers at a specific call site.\n\nThis feature is disabled by default and can be enabled with the `-F vtable` option (or using `features=vtable`).\nSee the [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/736) for more information.\n\nExample:\n\n```bash\nprofiler start -F vtable\n```\n\n## `comptask` feature\n\n`profiler` samples the JIT compiler threads as well as the Java threads, and can show the percentage of CPU consumed by JIT compilation. However, the compilation resource consumption of Java methods varies, and it is useful to know which specific Java methods consume the most CPU time when compiling.\n\nThe `comptask` feature adds a virtual frame to the stack trace of `C1/C2`, showing the current task being compiled, that is, the Java method being compiled.\n\nThis feature is disabled by default and can be enabled with the `-F comptask` option (or using `features=comptask`).\nSee [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/777) for more information.\n\nExample:\n\n```bash\nprofiler start -F comptask\n```\n\n## Configuring Alternative Profiling Signals\n\n`profiler` uses `POSIX` signals for performance profiling. By default, `SIGPROF` is used for `CPU` profiling and `SIGVTALRM` is used for `Wall-Clock` profiling. However, this can lead to signal conflicts if your application also uses these signals or if you want to run multiple `profiler` instances simultaneously.\n\nYou can now use the `signal` parameter to configure the signal used for profiling to avoid conflicts.\n\nSee [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/759) for more information.\n\nSyntax\n\n```bash\nprofiler start --signal <signal number>\n```\n\nIf you need to specify the signal for CPU and Wall-Clock analysis separately, you can use the following syntax:\n\n```bash\nprofiler start --signal <CPU signal number>/<Wall signal number>\n```\n\n## `--clock` option\n\nThe `--clock` option allows the user to control the clock source used for sampling timestamps. This is useful for scenarios where you need to align the timestamps of `profiler` data with data from other tools.\n\nUsage\n\n```bash\nprofiler start --clock <tsc|monotonic>\n```\n\nParameters\n\n- `tsc`: Use the CPU's timestamp counter (`RDTSC`). This is the default option and provides high-precision timestamps.\n\n- `monotonic`: Use the operating system's monotonic clock (`CLOCK_MONOTONIC`). This helps align timestamps between multiple data sources.\n  See [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/723) for more information.\n\nExample:\n\nUsing `CLOCK_MONOTONIC` as timestamp source:\n\n```bash\nprofiler start --clock monotonic\n```\n\n**Notes:**\n\n- Use `--clock monotonic` when you need to align `profiler` data with data from other tools that use `CLOCK_MONOTONIC` (e.g. `perf`).\n\n- Use `--clock` option with caution when using `jfrsync` mode, as the JVM and `profiler` may use different timestamp sources, which may lead to inconsistent results.\n\n## `--norm` option\n\nIn Java 20 and earlier, the method names generated by the compiler for `lambda` expressions contain a unique numeric suffix. For example, a `lambda` expression defined in the same code location may generate multiple different frame names, because each `lambda` method name is appended with a unique numeric suffix (such as `lambda$method$0`, `lambda$method$1`, etc.). This causes logically identical stacks to not be merged in the flame graph, increasing the complexity of performance analysis.\n\nTo solve this problem, `profiler` has added a `--norm` option that automatically normalizes method names when generating output, removes these numeric suffixes, and enables identical stacks to be merged correctly.\nPlease refer to [async-profiler Github Issues](https://github.com/async-profiler/async-profiler/issues/832) for more information.\n\n**Example:**\n\nGenerate a normalized flame graph:\n\n```bash\nprofiler start --norm\n```\n"

Reimplementing `redefine` function in the future will solve this problem.\n\n::: warning\nNotes: Re-defined classes cannot be restored. There are chances that redefining may fail due to some reasons, for example: there's new field introduced in the new version of the class, pls. refer to JDK's documentation for the limitations.\n:::\n\n::: tip\nThe `reset` command is not valid for classes that have been processed by `redefine`. If you want to reset, you need `redefine` the original bytecode.\n:::\n\n::: tip\nThe `redefine` command will conflict with the `jad`/`watch`/`trace`/`monitor`/`tt` commands. After executing `redefine`, if you execute the above mentioned command, the bytecode of the class will be reset.\nThe reason is that in the JDK `redefine` and `retransform` are different mechanisms. When two mechanisms are both used to update the bytecode, only the last modified will take effect.\n:::\n\n## Options\n\n|                  Name | Specification                                                   |\n| --------------------: | :-------------------------------------------------------------- |\n|                `[c:]` | hashcode of the class loader                                    |\n| `[classLoaderClass:]` | The class name of the ClassLoader that executes the expression. |\n\n## Usage\n\n```bash\nredefine /tmp/Test.class\nredefine -c 327a647b /tmp/Test.class /tmp/Test\\$Inner.class\nredefine --classLoaderClass sun.misc.Launcher$AppClassLoader /tmp/Test.class /tmp/Test\\$Inner.class\n```\n\n## Use with the jad/mc command\n\n```bash\njad --source-only com.example.demo.arthas.user.UserController > /tmp/UserController.java\n\nmc /tmp/UserController.java -d /tmp\n\nredefine /tmp/com/example/demo/arthas/user/UserController.class\n```\n\n- Use `jad` command to decompile bytecode, and then you can use other editors, such as vim to modify the source code.\n- `mc` command to compile the modified code\n- Load new bytecode with `redefine` command\n\n## Tips for uploading .class files to the server\n\nThe `mc` command may fail. You can modify the code locally, compile it, and upload it to the server. Some servers do not allow direct uploading files, you can use the `base64` command to bypass.\n\n1. Convert the `.class` file to base64 first, then save it as result.txt\n\n   ```bash\n   Base64 < Test.class > result.txt\n   ```\n\n2. Login the server, create and edit `result.txt`, copy the local content, paste and save\n\n3. Restore `result.txt` on the server to `.class`\n\n   ```\n   Base64 -d < result.txt > Test.class\n   ```\n\n4. Use the md5 command to verify that the `.class` files are consistent.\n\n## Restrictions of the redefine command\n\n- New field/method is not allowed\n- The function that is running, no exit can not take effect, such as the new `System.out.println` added below, only the `run()` function will take effect.\n\n```java\npublic class MathGame {\n    public static void main(String[] args) throws InterruptedException {\n        MathGame game = new MathGame();\n        while (true) {\n            game.run();\n            TimeUnit.SECONDS.sleep(1);\n            // This doesn't work because the code keeps running in while\n            System.out.println(\"in loop\");\n        }\n    }\n\n    public void run() throws InterruptedException {\n        // This works because the run() function ends completely every time\n        System.out.println(\"call run()\");\n        try {\n            int number = random.nextInt();\n            List<Integer> primeFactors = primeFactors(number);\n            print(number, primeFactors);\n\n        } catch (Exception e) {\n            System.out.println(String.format(\"illegalArgumentCount:%3d, \", illegalArgumentCount) + e.getMessage());\n        }\n    }\n}\n```\n"

Every time a `.class` file is loaded, a retransform entry is recorded.\n\n::: tip\nIf retransform is executed multiple times to load the same class file, there will be multiple retransform entries.\n:::\n\n## View retransform entry\n\n```bash\n$ retransform -l\nId              ClassName       TransformCount  LoaderHash      LoaderClassName\n1               demo.MathGame   1               null            null\n```\n\n- TransformCount counts the times of attempts to return the .class file corresponding to the entry in the ClassFileTransformer#transform method, but it does not mean that the transform must be successful.\n\n## Delete the specified retransform entry\n\nNeed to specify id:\n\n```bash\nretransform -d 1\n```\n\n## Delete all retransform entries\n\n```bash\nretransform --deleteAll\n```\n\n## Explicitly trigger retransform\n\n```bash\n$ retransform --classPattern demo.MathGame\nretransform success, size: 1, classes:\ndemo.MathGame\n```\n\n::: warning\nNote: For the same class, when there are multiple retransform entries, if retransform is explicitly triggered, the entry added last will take effect (the one with the largest id).\n:::\n\n## Eliminate the influence of retransform\n\nIf you want to eliminate the impact after performing retransform on a class, you need to:\n\n- Delete the retransform entry corresponding to this class\n- Re-trigger retransform\n\n::: tip\nIf you do not clear all retransform entries and trigger retransform again, the retransformed classes will still take effect when arthas stop.\n:::\n\n## Use with the jad/mc command\n\n```bash\njad --source-only com.example.demo.arthas.user.UserController > /tmp/UserController.java\n\nmc /tmp/UserController.java -d /tmp\n\nretransform /tmp/com/example/demo/arthas/user/UserController.class\n```\n\n- Use `jad` command to decompile bytecode, and then you can use other editors, such as vim to modify the source code.\n- `mc` command to compile the modified code\n- Load new bytecode with `retransform` command\n\n## Tips for uploading .class files to the server\n\nThe `mc` command may fail. You can modify the code locally, compile it, and upload it to the server. Some servers do not allow direct uploading files, you can use the `base64` command to bypass.\n\n1. Convert the `.class` file to base64 first, then save it as result.txt\n\n   ```bash\n   Base64 < Test.class > result.txt\n   ```\n\n2. Login the server, create and edit `result.txt`, copy the local content, paste and save\n\n3. Restore `result.txt` on the server to `.class`\n\n   ```\n   Base64 -d < result.txt > Test.class\n   ```\n\n4. Use the md5 command to verify that the `.class` files are consistent.\n\n## Restrictions of the retransform command\n\n- New field/method is not allowed\n- The function that is running, no exit can not take effect, such as the new `System.out.println` added below, only the `run()` function will take effect.\n\n```java\npublic class MathGame {\n    public static void main(String[] args) throws InterruptedException {\n        MathGame game = new MathGame();\n        while (true) {\n            game.run();\n            TimeUnit.SECONDS.sleep(1);\n            // This doesn't work because the code keeps running in while\n            System.out.println(\"in loop\");\n        }\n    }\n\n    public void run() throws InterruptedException {\n        // This works because the run() function ends completely every time\n        System.out.println(\"call run()\");\n        try {\n            int number = random.nextInt();\n            List<Integer> primeFactors = primeFactors(number);\n            print(number, primeFactors);\n\n        } catch (Exception e) {\n            System.out.println(String.format(\"illegalArgumentCount:%3d, \", illegalArgumentCount) + e.getMessage());\n        }\n    }\n}\n```\n"

The command `stack` comes to rescue in this difficult situation.\n\n## Parameters\n\n|                   Name | Specification                                                                                          |\n| ---------------------: | :----------------------------------------------------------------------------------------------------- |\n|        _class-pattern_ | pattern for the class name                                                                             |\n|       _method-pattern_ | pattern for the method name                                                                            |\n| _condition-expression_ | condition expression                                                                                   |\n|                  `[E]` | turn on regex match, the default behavior is wildcard match                                            |\n|                 `[n:]` | execution times                                                                                        |\n|                 `[c:]` | Specify classloader hash, only enhance classes loaded by it                                            |\n|            `[m <arg>]` | Specify the max number of matched Classes, the default value is 50. Long format is `[maxMatch <arg>]`. |\n\nThere's one thing worthy noting here is observation expression. The observation expression supports OGNL grammar, for example, you can come up a expression like this `\"{params,returnObj}\"`. All OGNL expressions are supported as long as they are legal to the grammar.\n\nThanks for `advice`'s data structure, it is possible to observe from varieties of different angles. Inside `advice` parameter, all necessary information for notification can be found.\n\nPls. refer to [core parameters in expression](advice-class.md) for more details.\n\n- Pls. also refer to [https://github.com/alibaba/arthas/issues/71](https://github.com/alibaba/arthas/issues/71) for more advanced usage\n- OGNL official site: [https://commons.apache.org/dormant/commons-ognl/language-guide.html](https://commons.apache.org/dormant/commons-ognl/language-guide.html)\n\n## Usage\n\n### Start Demo\n\nStart `math-game` in [Quick Start](quick-start.md).\n\n### stack\n\n```bash\n$ stack demo.MathGame primeFactors\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 36 ms.\nts=2018-12-04 01:32:19;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    @demo.MathGame.run()\n        at demo.MathGame.main(MathGame.java:16)\n```\n\n### Specify the max number of matched Classes\n\n```bash\n$ stack demo.MathGame primeFactors -m 1\nPress Q or Ctrl+C to abort.\nAffect(class count:1 , method count:1) cost in 561 ms, listenerId: 5.\nts=2022-12-25 21:07:07;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@b4aac2\n    @demo.MathGame.primeFactors()\n        at demo.MathGame.run(MathGame.java:46)\n        at demo.MathGame.main(MathGame.java:38)\n```\n\n### Specify ClassLoader to enhance\n\nIf the same class is loaded by multiple classloaders, you can use `sc -d` to find the classloader hash and then use `-c` to enhance only the specified one:\n\n```bash\nsc -d com.example.Foo\nstack -c 3d4eac69 com.example.Foo bar\n```\n\n### Filtering by condition expression\n\n```bash\n$ stack demo.MathGame primeFactors 'params[0]<0' -n 2\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 30 ms.\nts=2018-12-04 01:34:27;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    @demo.MathGame.run()\n        at demo.MathGame.main(MathGame.java:16)\n\nts=2018-12-04 01:34:30;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    @demo.MathGame.run()\n        at demo.MathGame.main(MathGame.java:16)\n\nCommand execution times exceed limit: 2, so command will exit. You can set it with -n option.\n```\n\n### Filtering by cost\n\n```bash\n$ stack demo.MathGame primeFactors '#cost>5'\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 35 ms.\nts=2018-12-04 01:35:58;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    @demo.MathGame.run()\n        at demo.MathGame.main(MathGame.java:16)\n```\n"

Arthas allows multiple users to access simultaneously without interfering with each other.\n- _PORT_: Arthas Server port，the default value is 3658\n\n### Sample\n\n- If IP and PORT are not specified, then the default values are 127.0.0.1 and 3658\n\n  > ./as.sh 12345\n\n  Equivalent to:\n\n  > ./as.sh 12356@127.0.0.1:3658\n\n### Remote Diagnosis\n\nAfter starting Arthas Server on the target Java process, users can use `telnet` connect to the remote Arthas Server, for example：\n\n```bash\ntelnet 192.168.1.119 3658\n```\n\n### sudo Support\n\nUsually online environment will only grant users privilege as low as possible, instead, all advanced operations are through sudo-list. Since `as.sh` script takes into account the current effective user, it is possible to run the script in the other rule, by specifying `-H` option like this:\n\n```bash\nsudo -u admin -H ./as.sh 12345\n```\n\n### Windows Support\n\nRight now `as.bat` script supports one parameter only, which is: pid\n\n```bash\nas.bat <pid>\n```\n"

During a sampling interval,\nthe ratio of the incremental cpu time of each thread in the current JVM to the sampling interval time.\n\n### Working principle description:\n\n- Do the first sampling, get the CPU time of all threads ( by calling `java.lang.management.ThreadMXBean#getThreadCpuTime()` and\n  `sun.management.HotspotThreadMBean.getInternalThreadCpuTimes()` )\n- Sleep and wait for an interval (the default is 200ms, the interval can be specified by `-i`)\n- Do the second sampling, get the CPU time of all threads, compare the two sampling data, and calculate the incremental CPU time of each thread\n- `Thread CPU usage ratio` = `Thread increment CPU time` / `Sampling interval time` \\* 100%\n\n> Note: this operation consumes CPU time too (`getThreadCpuTime` is time-consuming), therefore it is possible to observe Arthas's thread appears in the list. To avoid this, try to increase sample interval, for example: 5000 ms.<br/>\n\n> Another way to view the thread cpu usage of the Java process, [`show-busy-java-threads`](https://github.com/oldratlee/useful-scripts/blob/dev-2.x/docs/java.md#-show-busy-java-threads) can come to help.\n\n## Usage\n\n### List the top n busiest threads with detailed stack trace\n\n```shell\n$ thread -n 3\n\"C1 CompilerThread0\" [Internal] cpuUsage=1.63% deltaTime=3ms time=1170ms\n\n\n\"arthas-command-execute\" Id=23 cpuUsage=0.11% deltaTime=0ms time=401ms RUNNABLE\n    at java.management@11.0.7/sun.management.ThreadImpl.dumpThreads0(Native Method)\n    at java.management@11.0.7/sun.management.ThreadImpl.getThreadInfo(ThreadImpl.java:466)\n    at com.taobao.arthas.core.command.monitor200.ThreadCommand.processTopBusyThreads(ThreadCommand.java:199)\n    at com.taobao.arthas.core.command.monitor200.ThreadCommand.process(ThreadCommand.java:122)\n    at com.taobao.arthas.core.shell.command.impl.AnnotatedCommandImpl.process(AnnotatedCommandImpl.java:82)\n    at com.taobao.arthas.core.shell.command.impl.AnnotatedCommandImpl.access$100(AnnotatedCommandImpl.java:18)\n    at com.taobao.arthas.core.shell.command.impl.AnnotatedCommandImpl$ProcessHandler.handle(AnnotatedCommandImpl.java:111)\n    at com.taobao.arthas.core.shell.command.impl.AnnotatedCommandImpl$ProcessHandler.handle(AnnotatedCommandImpl.java:108)\n    at com.taobao.arthas.core.shell.system.impl.ProcessImpl$CommandProcessTask.run(ProcessImpl.java:385)\n    at java.base@11.0.7/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515)\n    at java.base@11.0.7/java.util.concurrent.FutureTask.run(FutureTask.java:264)\n    at java.base@11.0.7/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:304)\n    at java.base@11.0.7/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128)\n    at java.base@11.0.7/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628)\n    at java.base@11.0.7/java.lang.Thread.run(Thread.java:834)\n\n\n\"VM Periodic Task Thread\" [Internal] cpuUsage=0.07% deltaTime=0ms time=584ms\n```\n\n- Without thread ID, including `[Internal]` means JVM internal thread, refer to the introduction of [dashboard](dashboard.md) command.\n- `cpuUsage` is the CPU usage of the thread during the sampling interval, consistent with the data of the [dashboard](dashboard.md) command.\n- `deltaTime` is the incremental CPU time of the thread during the sampling interval. If it is less than 1ms, it will be rounded and displayed as 0ms.\n- `time` The total CPU time of thread.\n\n**Note:** The thread stack is acquired at the end of the second sampling, which does not indicate that the thread is\nprocessing the same task during the sampling interval. It is recommended that the interval time should not be too long.\nThe larger the interval time, the more inaccurate.\n\nYou can try to specify different intervals according to the specific situation and observe the output results.\n\n### List first page threads' info when no options provided\n\nBy default, they are arranged in descending order of CPU increment time, and only the first page of data is displayed.\n\n```shell\n$ thread\nThreads Total: 33, NEW: 0, RUNNABLE: 9, BLOCKED: 0, WAITING: 3, TIMED_WAITING: 4, TERMINATED: 0, Internal threads: 17\nID   NAME                           GROUP          PRIORITY  STATE     %CPU      DELTA_TIME TIME      INTERRUPT DAEMON\n-1   C2 CompilerThread0             -              -1        -         5.06      0.010      0:0.973   false     true\n-1   C1 CompilerThread0             -              -1        -         0.95      0.001      0:0.603   false     true\n23   arthas-command-execute         system         5         RUNNABLE  0.17      0.000      0:0.226   false     true\n-1   VM Periodic Task Thread        -              -1        -         0.05      0.000      0:0.094   false     true\n-1   Sweeper thread                 -              -1        -         0.04      0.000      0:0.011   false     true\n-1   G1 Young RemSet Sampling       -              -1        -         0.02      0.000      0:0.025   false     true\n12   Attach Listener                system         9         RUNNABLE  0.0       0.000      0:0.022   false     true\n11   Common-Cleaner                 InnocuousThrea 8         TIMED_WAI 0.0       0.000      0:0.000   false     true\n3    Finalizer                      system         8         WAITING   0.0       0.000      0:0.000   false     true\n2    Reference Handler              system         10        RUNNABLE  0.0       0.000      0:0.000   false     true\n4    Signal Dispatcher              system         9         RUNNABLE  0.0       0.000      0:0.000   false     true\n15   arthas-NettyHttpTelnetBootstra system         5         RUNNABLE  0.0       0.000      0:0.029   false     true\n22   arthas-NettyHttpTelnetBootstra system         5         RUNNABLE  0.0       0.000      0:0.196   false     true\n24   arthas-NettyHttpTelnetBootstra system         5         RUNNABLE  0.0       0.000      0:0.038   false     true\n16   arthas-NettyWebsocketTtyBootst system         5         RUNNABLE  0.0       0.000      0:0.001   false     true\n17   arthas-NettyWebsocketTtyBootst system         5         RUNNABLE  0.0       0.000      0:0.001   false     true\n```\n\n### thread --all, show all matching threads\n\nDisplay all matching threads.

It is possible to achieve this in Arthas, for example: `trace *StringUtils isBlank '#cost>100'` means trace result will only be output when the executing time exceeds 100ms.\n\n::: tip\n`watch`/`stack`/`trace`, these three commands all support `#cost`.\n:::\n\n## Notice\n\n- `trace` is handy to help discovering and locating the performance flaws in your system, but pls. note Arthas can only trace the first level method call each time.\n\n- After version 3.3.0, you can use the Dynamic Trace feature to add new matching classes/methods, see the following example.\n\n- Currently `trace java.lang.Thread getName` is not supported, please refer to issue: [#1610](https://github.com/alibaba/arthas/issues/1610), considering that it is not very necessary and it is difficult to repair , So it won’t be fixed for now\n\n## Usage\n\n### Start Demo\n\nStart `math-game` in [Quick Start](quick-start.md).\n\n### Trace method\n\n```bash\n$ trace demo.MathGame run\nPress Q or Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 28 ms.\n`---ts=2019-12-04 00:45:08;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[0.617465ms] demo.MathGame:run()\n        `---[0.078946ms] demo.MathGame:primeFactors() #24 [throws Exception]\n\n`---ts=2019-12-04 00:45:09;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[1.276874ms] demo.MathGame:run()\n        `---[0.03752ms] demo.MathGame:primeFactors() #24 [throws Exception]\n```\n\n::: tip\nThe `#24` in the result indicates that in the run function, the `primeFactors()` function was called on line `24` of the source file.\n:::\n\n### Specify the max number of matched Classes\n\n```bash\n$ trace demo.MathGame run -m 1\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 412 ms, listenerId: 4\n`---ts=2022-12-25 21:00:00;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@b4aac2\n    `---[0.762093ms] demo.MathGame:run()\n        `---[30.21% 0.230241ms] demo.MathGame:primeFactors() #46 [throws Exception]\n\n`---ts=2022-12-25 21:00:10;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@b4aac2\n    `---[0.315298ms] demo.MathGame:run()\n        `---[13.95% 0.043995ms] demo.MathGame:primeFactors() #46 [throws Exception]\n```\n\n### Specify ClassLoader to enhance\n\nIf the same class is loaded by multiple classloaders, you can use `sc -d` to find the classloader hash and then use `-c` to enhance only the specified one:\n\n```bash\nsc -d com.example.Foo\ntrace -c 3d4eac69 com.example.Foo bar\n```\n\n### Trace times limit\n\nIf the method invoked many times, use `-n` options to specify trace times. For example, the command will exit when received a trace result.\n\n```bash\n$ trace demo.MathGame run -n 1\nPress Q or Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 20 ms.\n`---ts=2019-12-04 00:45:53;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[0.549379ms] demo.MathGame:run()\n        +---[0.059839ms] demo.MathGame:primeFactors() #24\n        `---[0.232887ms] demo.MathGame:print() #25\n\nCommand execution times exceed limit: 1, so command will exit. You can set it with -n option.\n```\n\n### Include jdk method\n\n- `--skipJDKMethod <value> ` skip jdk method trace, default value true.\n\n```bash\n$ trace --skipJDKMethod false demo.MathGame run\nPress Q or Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 60 ms.\n`---ts=2019-12-04 00:44:41;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[1.357742ms] demo.MathGame:run()\n        +---[0.028624ms] java.util.Random:nextInt() #23\n        +---[0.045534ms] demo.MathGame:primeFactors() #24 [throws Exception]\n        +---[0.005372ms] java.lang.StringBuilder:<init>() #28\n        +---[0.012257ms] java.lang.Integer:valueOf() #28\n        +---[0.234537ms] java.lang.String:format() #28\n        +---[min=0.004539ms,max=0.005778ms,total=0.010317ms,count=2] java.lang.StringBuilder:append() #28\n        +---[0.013777ms] java.lang.Exception:getMessage() #28\n        +---[0.004935ms] java.lang.StringBuilder:toString() #28\n        `---[0.06941ms] java.io.PrintStream:println() #28\n\n`---ts=2019-12-04 00:44:42;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[3.030432ms] demo.MathGame:run()\n        +---[0.010473ms] java.util.Random:nextInt() #23\n        +---[0.023715ms] demo.MathGame:primeFactors() #24 [throws Exception]\n        +---[0.005198ms] java.lang.StringBuilder:<init>() #28\n        +---[0.006405ms] java.lang.Integer:valueOf() #28\n        +---[0.178583ms] java.lang.String:format() #28\n        +---[min=0.011636ms,max=0.838077ms,total=0.849713ms,count=2] java.lang.StringBuilder:append() #28\n        +---[0.008747ms] java.lang.Exception:getMessage() #28\n        +---[0.019768ms] java.lang.StringBuilder:toString() #28\n        `---[0.076457ms] java.io.PrintStream:println() #28\n```\n\n### Filtering by cost\n\n```bash\n$ trace demo.MathGame run '#cost > 10'\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 41 ms.\n`---ts=2018-12-04 01:12:02;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[12.033735ms] demo.MathGame:run()\n        +---[0.006783ms] java.util.Random:nextInt()\n        +---[11.852594ms] demo.MathGame:primeFactors()\n        `---[0.05447ms] demo.MathGame:print()\n```\n\n::: tip\nOnly the call path which's time cost is higher than `10ms` will be shown. This feature is handy to focus on what's needed to focus when troubleshoot.\n:::\n\n- Here Arthas provides the similar functionality JProfile and other commercial software provide. Compared to these professional softwares, Arthas doesn't deduce the time cost `trace` itself takes, therefore it is not as accurate as these softwares offer. More classes and methods on the calling path, more inaccurate `trace` output is, but it is still helpful for diagnostics where the bottleneck is.\n- \"[12.033735ms]\" means the method on the node takes `12.033735` ms.\n- \"[min=0.005428ms,max=0.094064ms,total=0.105228ms,count=3] demo:call()\" means aggregating all same method calls into one single line. The minimum time cost is `0.005428` ms, the maximum time cost is `0.094064` ms, and the total time cost for all method calls (`3` times in total) to \"demo:call()\" is `0.105228ms`. If \"throws Exception\" appears in this line, it means some exceptions have been thrown from this method calls.\n- The total time cost may not equal to the sum of the time costs each sub method call takes, this is because Arthas instrumented code takes time too.\n\n### Trace multiple classes or multiple methods\n\nThe trace command will only trace the subcalls in the method to the trace, and will not trace down multiple layers. Because traces are expensive, multi-layer traces can lead to a lot of classes and methods that ultimately have to be traced.\n\nYou can use the regular expression to match multiple classes and methods on the path to achieve a multi-layer trace effect to some extent.\n\n```bash\nTrace -E com.test.ClassA|org.test.ClassB method1|method2|method3\n```\n\n### Exclude the specified class\n\n::: tip\nThe watch/trace/monitor/stack/tt commands all support the `--exclude-class-pattern` parameter\n:::\n\nUse the `--exclude-class-pattern` parameter to exclude the specified class, for example:\n\n```bash\nwatch javax.servlet.Filter * --exclude-class-pattern com.demo.TestFilter\n```\n\n### Dynamic trace\n\n::: tip\nSupported since version 3.3.0.\n:::\n\nOpen terminal 1, trace the `run` method in the above demo, and you can see the printout `listenerId: 1` .\n\n```bash\n[arthas@59161]$ trace demo.MathGame run\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 112 ms, listenerId: 1\n`---ts=2020-07-09 16:48:11;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[1.389634ms] demo.MathGame:run()\n        `---[0.123934ms] demo.MathGame:primeFactors() #24 [throws Exception]\n\n`---ts=2020-07-09 16:48:12;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[3.716391ms] demo.MathGame:run()\n        +---[3.182813ms] demo.MathGame:primeFactors() #24\n        `---[0.167786ms] demo.MathGame:print() #25\n```\n\nNow to drill down into the sub method `primeFactors`, you can open a new terminal 2 and use the `telnet localhost 3658` connects to the arthas, then trace `primeFactors` with the specify `listenerId`.\n\n```bash\n[arthas@59161]$ trace demo.MathGame primeFactors --listenerId 1\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 34 ms, listenerId: 1\n```\n\nAt Terminal 2 prints the results, indicating that a method has been enhanced: `Affect(class count: 1 , method count: 1)`, but no more results are printed.\n\nAt terminal 1, you can see that the trace result has increased by one layer:\n\n```bash\n`---ts=2020-07-09 16:49:29;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[0.492551ms] demo.MathGame:run()\n        `---[0.113929ms] demo.MathGame:primeFactors() #24 [throws Exception]\n            `---[0.061462ms] demo.MathGame:primeFactors()\n                `---[0.001018ms] throw:java.lang.IllegalArgumentException() #46\n\n`---ts=2020-07-09 16:49:30;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@3d4eac69\n    `---[0.409446ms] demo.MathGame:run()\n        +---[0.232606ms] demo.MathGame:primeFactors() #24\n        |   `---[0.1294ms] demo.MathGame:primeFactors()\n        `---[0.084025ms] demo.MathGame:print() #25\n```\n\nDynamic trace by specifying `listenerId`, you can go deeper and deeper. In addition, commands such as `watch`/`tt`/`monitor` also support similar functionality.\n\n## Trace result time inaccuracy problem\n\nFor example, in the following result: `0.705196 > (0.152743 + 0.145825)`\n\n```bash\n$ trace demo.MathGame run -n 1\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 66 ms, listenerId: 1\n`---ts=2021-02-08 11:27:36;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@232204a1\n    `--[0.705196ms] demo.MathGame:run()\n        +---[0.152743ms] demo.MathGame:primeFactors() #24\n        `--[0.145825ms] demo.MathGame:print() #25\n```\n\nSo where is the rest of the time consumed?\n\n1. Methods that are not traced to. For example, methods under `java.*` are ignored by default. This can be printed out by adding the `-skipJDKMethod false` parameter.\n\n   ```bash\n   $ trace demo.MathGame run --skipJDKMethod false\n   Press Q or Ctrl+C to abort.\n   Affect(class count: 1 , method count: 1) cost in 35 ms, listenerId: 2\n   `---ts=2021-02-08 11:27:48;thread_name=main;id=1;is_daemon=false;priority=5;TCCL=sun.misc.Launcher$AppClassLoader@232204a1\n       `--[0.810591ms] demo.MathGame:run()\n           +--[0.034568ms] java.util.Random:nextInt() #23\n           +---[0.119367ms] demo.MathGame:timeFactors() #24 [throws Exception]\n           +---[0.017407ms] java.lang.StringBuilder:<init>() #28\n           +--[0.127922ms] java.lang.String:format() #57\n           +---[min=0.01419ms,max=0.020221ms,total=0.034411ms,count=2] java.lang.StringBuilder:append() #57\n           +--[0.021911ms] java.lang.Exception:getMessage() #57\n           +---[0.015643ms] java.lang.StringBuilder:toString() #57\n           `--[0.086622ms] java.io.PrintStream:println() #57\n   ```\n\n2. Instruction consumption. For example, instructions such as `i++`, `getfield`, etc.\n\n3. Possible JVM pause during code execution, such as GC, entering synchronization blocks, etc.\n\n### Use the -v parameter to print more information\n\n::: tip\nThe watch/trace/monitor/stack/tt commands all support the `-v` parameter.\n:::\n\nWhen the command is executed, there is no output result. There are two possibilities:\n\n1. The matched function is not executed\n2. The result of the conditional expression is false\n\nBut the user cannot tell which situation is.\n\nUsing the `-v` option, the specific value and execution result of `Condition express` will be printed for easy confirmation.\n"

    "content": "# Arthas Tunnel\n\nManage/connect multiple Agents remotely via Arthas Tunnel Server/Client.\n\nFor example, in streaming computing, Java processes can be started on different machines, and it can be difficult to use Arthas to diagnose them, because the user usually does not have access to the machine.\n\nIn this case, Arthas Tunnel Server/Client can be used.\n\nReference:\n\n- 1: [Web Console](web-console.md)\n- 2: [Arthas Spring Boot Starter](spring-boot-starter.md)\n\n## Download and deploy arthas tunnel server\n\n[https://github.com/alibaba/arthas/releases](https://github.com/alibaba/arthas/releases)\n\nArthas tunnel server is a spring boot fat jar application, start with the `java -jar` command:\n\n```bash\njava -jar  arthas-tunnel-server.jar\n```\n\nBy default, the web port of the arthas tunnel server is `8080`, and the port connected by the arthas agent is `7777`.\n\nOnce started, you can go to [http://127.0.0.1:8080/](http://127.0.0.1:8080/) and connect to the registered arthas agent via `agentId`.\n\nThrough Spring Boot's Endpoint, you can view the specific connection information: [http://127.0.0.1:8080/actuator/arthas](http://127.0.0.1:8080/actuator/arthas), the login user name is `arthas`, and the password can be found in the log of arthas tunnel server, for example:\n\n```\n32851 [main] INFO o.s.b.a.s.s.UserDetailsServiceAutoConfiguration\n\nUsing generated security password: f1dca050-3777-48f4-a577-6367e55a78a2\n```\n\n## Connecting to the tunnel server when starting arthas\n\nWhen starting arthas, you can use the `--tunnel-server` parameter, for example:\n\n```bash\nas.sh --tunnel-server 'ws://127.0.0.1:7777/ws'\n```\n\nYou can also use the following test address (not guaranteed to be available all the time):\n\n```bash\nas.sh --tunnel-server 'ws://47.75.156.201:80/ws'\n```\n\n- You can specify the agentId by the `--agent-id` parameter. By default, a random ID is generated.\n\nAfter Arthas attach succeeds, the agentId will be printed, such as:\n\n```bash\n  ,---.  ,------. ,--------.,--.  ,--.  ,---.   ,---.\n /  O  \\ |  .--. ''--.  .--'|  '--'  | /  O  \\ '   .-'\n|  .-.  ||  '--'.'   |  |   |  .--.  ||  .-.  |`.  `-.\n|  | |  ||  |\\  \\    |  |   |  |  |  ||  | |  |.-'    |\n`--' `--'`--' '--'   `--'   `--'  `--'`--' `--'`-----'\n\n\nwiki      https://arthas.aliyun.com/doc\ntutorials https://arthas.aliyun.com/doc/arthas-tutorials.html\nversion   3.1.2\npid       86183\ntime      2019-08-30 15:40:53\nid        URJZ5L48RPBR2ALI5K4V\n```\n\nIf the connection is not connected to the tunnel server at startup, you can also obtain the agentId through the `session` command after reconnection succeeds:\n\n```bash\n[arthas@86183]$ session\n Name           Value\n-----------------------------------------------------\n JAVA_PID       86183\n SESSION_ID     f7273eb5-e7b0-4a00-bc5b-3fe55d741882\n AGENT_ID       URJZ5L48RPBR2ALI5K4V\n TUNNEL_SERVER  ws://47.75.156.201:80/ws\n```\n\nFor the above example, go to [http://47.75.156.201/arthas/?port=80](http://47.75.156.201/arthas/?port=80) in the browser and input the `agentId` to connect to arthas on remote machine.\n\n![](/images/arthas-tunnel-server.png)\n\n## Best practices\n\n::: warning\nNote that the agentId must be unique, otherwise it will conflict on the tunnel server and not work properly.\n:::\n\nIf the arthas agent is configured with `appName`, the generated agentId will be prefixed with `appName`.\n\nFor example, if you add the startup parameter `as.sh --tunnel-server 'ws://127.0.0.1:7777/ws' --app-name demoapp`, the generated agentId might be `demoapp_URJZ5L48RPBR2ALI5K4V`.\n\nTunnel server will use `_` as a delimiter to extract `appName`, which is convenient to manage by application.\n\n::: tip\nAlternatively, you can configure `appName` in `arthas.properties` in the unzipped arthas directory, or in `application.properties` of the spring boot application.\n:::\n\n## Tunnel Server Management Page\n\n::: tip\nYou need to configure `arthas.enable-detail-pages=true` in `application.properties` of tunnel-server, or you can specify it with command line parameters: `java -Darthas.enable-detail-pages=true -jar arthas-tunnel-server.jar`\n\nSupported configuration: [tunnel-server application.properties](https://github.com/alibaba/arthas/blob/master/tunnel-server/src/main/resources/application.properties)\n\n**Attention, opening the management page is risky! The management page is not authenticated, so you must add security measures yourself, and do not open it to the public network. **\n:::\n\nStart the tunnel-server locally, then use `as.sh` attach, and specify the application name `--app-name test`:\n\n```\n$ as.sh --tunnel-server 'ws://127.0.0.1:7777/ws' --app-name test\ntelnet connecting to arthas server... current timestamp is 1627539688\nTrying 127.0.0.1...\nConnected to 127.0.0.1.\nEscape character is '^]'.\n  ,---.  ,------. ,--------.,--.  ,--.  ,---.   ,---.\n /  O  \\ |  .--.

Users need to develop by themselves and authenticate the app name.\n2. If the management page is opened, security measures need to be added.\n\n## Cluster Management\n\nIf you want to deploy multiple tunnel servers, you can use nginx for forwarding and redis to store agent information.\n\nNginx needs to configure sticky session to ensure that the user's web socket is connected to the same back-end tunnel server. The simple configuration method is to use `ip_hash`.\n\n## How arthas tunnel server works\n\n```\nbrowser <-> arthas tunnel server <-> arthas tunnel client <-> arthas agent\n```\n\n[tunnel-server/README.md](https://github.com/alibaba/arthas/blob/master/tunnel-server/README.md#)\n"

Long format is `[maxMatch <arg>]`. |\n\nF.Y.I\n\n1. any valid OGNL expression as `\"{params,returnObj}\"` supported\n2. there are four _watching_ points: `-b`, `-e`, `-s` and `-f` (the first three are off in default while `-f` on);\n3. at the _watching_ point, Arthas will use the _expression_ to evaluate the variables and print them out;\n4. `in parameters` and `out parameters` are different since they can be modified within the invoked methods; `params` stands for `in parameters` in `-b`while `out parameters` in other _watching_ points;\n5. there are no `return values` and `exceptions` when using `-b`.\n6. In the result of the watch command, the `location` information will be printed. There are three possible values for `location`: `AtEnter`, `AtExit`, and `AtExceptionExit`. Corresponding to the method entry, the method returns normally, and the method throws an exception.\n\nAdvanced:\n\n- [Critical fields in _expression_](advice-class.md)\n- [Special usages](https://github.com/alibaba/arthas/issues/71)\n- [OGNL official guide](https://commons.apache.org/dormant/commons-ognl/language-guide.html)\n\n## Usage\n\n### Start Demo\n\nStart `math-game` in [Quick Start](quick-start.md).\n\n### Check the `out parameters`, `this` and `return value`\n\n::: tip\nThe expression to watch, default value `{params, target, returnObj}`\n:::\n\n```bash\n$ watch demo.MathGame primeFactors -x 2\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 32 ms, listenerId: 5\nmethod=demo.MathGame.primeFactors location=AtExceptionExit\nts=2021-08-31 15:22:57; [cost=0.220625ms] result=@ArrayList[\n    @Object[][\n        @Integer[-179173],\n    ],\n    @MathGame[\n        random=@Random[java.util.Random@31cefde0],\n        illegalArgumentCount=@Integer[44],\n    ],\n    null,\n]\nmethod=demo.MathGame.primeFactors location=AtExit\nts=2021-08-31 15:22:58;

Users can specify the field in the `ognl` expression.\n\n### Use condition expressions to locate specific call\n\n```bash\n$ watch demo.MathGame primeFactors \"{params[0],target}\" \"params[0]<0\"\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 68 ms.\nts=2018-12-03 19:36:04; [cost=0.530255ms] result=@ArrayList[\n    @Integer[-18178089],\n    @MathGame[demo.MathGame@41cf53f9],\n]\n```\n\n### Check `exceptions`\n\n```bash\n$ watch demo.MathGame primeFactors \"{params[0],throwExp}\" -e -x 2\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 62 ms.\nts=2018-12-03 19:38:00; [cost=1.414993ms] result=@ArrayList[\n    @Integer[-1120397038],\n    java.lang.IllegalArgumentException: number is: -1120397038, need >= 2\n\tat demo.MathGame.primeFactors(MathGame.java:46)\n\tat demo.MathGame.run(MathGame.java:24)\n\tat demo.MathGame.main(MathGame.java:16)\n,\n]\n```\n\n- `-e`\b: Trigger when an exception is thrown\n- `throwExp`: the exception object\n\n### Filter by time cost\n\n```bash\n$ watch demo.MathGame primeFactors '{params, returnObj}' '#cost>200' -x 2\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 66 ms.\nts=2018-12-03 19:40:28; [cost=2112.168897ms] result=@ArrayList[\n    @Object[][\n        @Integer[1],\n    ],\n    @ArrayList[\n        @Integer[5],\n        @Integer[428379493],\n    ],\n]\n```\n\n- `#cost>200` (`ms`) filter out all invokings that take less than `200ms`.\n\n### Check the field of the target object\n\n- `target` is the `this` object in java.\n\n```bash\n$ watch demo.MathGame primeFactors 'target'\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 52 ms.\nts=2018-12-03 19:41:52; [cost=0.477882ms] result=@MathGame[\n    random=@Random[java.util.Random@522b408a],\n    illegalArgumentCount=@Integer[13355],\n]\n```\n\n- `target.field_name`: the field of the current object.\n\n```bash\n$ watch demo.MathGame primeFactors 'target.illegalArgumentCount'\nPress Ctrl+C to abort.\nAffect(class-cnt:1 , method-cnt:1) cost in 67 ms.\nts=2018-12-03 20:04:34; [cost=131.303498ms] result=@Integer[8]\nts=2018-12-03 20:04:35; [cost=0.961441ms] result=@Integer[8]\n```\n\n### Get a static field and calling a static method\n\n```bash\nwatch demo.MathGame * '{params,@demo.MathGame@random.nextInt(100)}' -v -n 1 -x 2\n[arthas@6527]$ watch demo.MathGame * '{params,@demo.MathGame@random.nextInt(100)}' -n 1 -x 2\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 5) cost in 34 ms, listenerId: 3\nts=2021-01-05 21:35:20; [cost=0.173966ms] result=@ArrayList[\n    @Object[][\n        @Integer[-138282],\n    ],\n    @Integer[89],\n]\n```\n\n- Note that here you use `Thread.currentThread().getContextClassLoader()` to load, and it is better to use the exact `classloader` [ognl](ognl.md).\n\n### Exclude the specified class\n\n::: tip\nThe watch/trace/monitor/stack/tt commands all support the `--exclude-class-pattern` parameter\n:::\n\nUse the `--exclude-class-pattern` parameter to exclude the specified class, for example:\n\n```bash\nwatch javax.servlet.Filter * --exclude-class-pattern com.demo.TestFilter\n```\n\n### Does not match subclass\n\nBy default, the watch/trace/monitor/stack/tt commands will match subclass. If you don't want to match, you can turn it off.\n\n```bash\noptions disable-sub-class true\n```\n\n### Use the -v parameter to print more information\n\n> The watch/trace/monitor/stack/tt commands all support the `-v` parameter.\n\nWhen the command is executed, there is no output result. There are two possibilities:\n\n1. The matched function is not executed\n2. The result of the conditional expression is false\n\nBut the user cannot tell which situation is.\n\nUsing the `-v` option, the specific value and execution result of `Condition express` will be printed for easy confirmation.\n\nsuch as:\n\n```\n$ watch -v -x 2 demo.MathGame print 'params' 'params[0] > 100000'\nPress Q or Ctrl+C to abort.\nAffect(class count: 1 , method count: 1) cost in 29 ms, listenerId: 11\nCondition express: params[0] > 100000 , result: false\nCondition express: params[0] > 100000 , result: false\nCondition express: params[0] > 100000 , result: true\nts=2020-12-02 22:38:56; [cost=0.060843ms] result=@Object[][\n    @Integer[1],\n    @ArrayList[\n        @Integer[200033],\n    ],\n]\nCondition express: params[0] > 100000 , result: true\nts=2020-12-02 22:38:57; [cost=0.052877ms] result=@Object[][\n    @Integer[1],\n    @ArrayList[\n        @Integer[29],\n        @Integer[4243],\n    ],\n]\n```\n"

CPU 飙高排查\n\n**文件：** `cpu-high/SKILL.md`\n\n适用场景：机器 CPU 飙高、应用响应变慢、负载异常升高。\n\n核心步骤：\n1. `dashboard` 查看 CPU / 线程 / GC 概况\n2. `thread`（topN）定位最忙线程及堆栈\n3. 根据堆栈判断方向（CPU 密集计算 / 锁竞争 / GC 等）\n4. 按需用 `stack` / `trace` / `watch` 进一步确认热点方法调用路径\n5. 输出诊断结论（现象、证据、初步结论、下一步建议）\n\n---\n\n### 2. 获取 EagleEye traceId\n\n**文件：** `eagleeye-traceid/SKILL.md`\n\n适用场景：需要在不改代码的情况下，获取线上请求的 EagleEye traceId，用于关联日志 / 链路分析。\n\n核心步骤：\n1. `sc -d com.taobao.eagleeye.EagleEye` 确认类存在\n2. 选择合适的观察点（Controller / RPC Provider / Filter 等入口方法）\n3. **方案 A**：`watch` + OGNL 表达式 `@com.taobao.eagleeye.EagleEye@getTraceId()` 直接打印 traceId\n4. **方案 B**：`trace` 输出中自动带出 traceId，同时可看调用链耗时\n5. 拿到 traceId 后去日志 / 链路系统查询对应请求\n\n---\n\n### 3. Spring Context / Bean 排查\n\n**文件：** `spring-context/SKILL.md`\n\n适用场景：排查 Spring ApplicationContext / Bean / 配置注入等问题。\n\n核心步骤：\n1. `vmtool --action getInstances` 获取 `AbstractApplicationContext` 实例（注意通过 ClassLoader 区分正确的 Context）\n2. 获取配置项的值与来源（`getEnvironment().getProperty(...)` / `findConfigurationProperty(...)`）\n3. `containsBean` / `containsLocalBean` / `containsBeanDefinition` 验证 Bean 是否存在（不触发初始化）\n4. 按关键词过滤搜索 Bean（`getBeanDefinitionNames` + OGNL 过滤）\n5. 按类型查找 Bean（`getBeanNamesForType` / `getBeansOfType`）\n6. 查看 BeanDefinition 确认 Bean 注册来源（`@Bean` 工厂方法 / XML / 自动扫描）\n\n**注意：** 先只读查询，避免直接 `getBean()` 触发 Bean 初始化产生副作用；若遇到 `ClassNotFound`，通常是类加载器不对，需先用 `classloader` 命令找到正确的 `classLoaderHash`。\n"

    "content": "---\nname: arthas-eagleeye-traceid\ndescription: 使用 Arthas 的 watch/trace 获取 EagleEye traceId / 获取请求的 traceId\n---\n\n# 获取 EagleEye traceId（Arthas）\n\n适用场景：你需要在不改代码的情况下，在线上请求链路里拿到当前线程的 EagleEye `traceId`，用于关联日志/链路分析/问题复现。\n\n核心思路：\n- EagleEye 的 traceId 可在业务线程里通过 `EagleEye.getTraceId()` 获取。\n- Arthas 的 `watch` 支持 OGNL，可直接调用静态方法：`@com.taobao.eagleeye.EagleEye@getTraceId()`\n- Arthas 的 `trace` 输出中通常会自动包含 `trace_id=...`（如果环境集成了 EagleEye）。\n\n## 前置检查（推荐）\n\n1) 确认 EagleEye 类是否存在：\n\n```bash\nsc -d com.taobao.eagleeye.EagleEye\n```\n\n若找不到：\n- 可能未集成 EagleEye、或类被 relocate/shade（请让用户提供实际类名/依赖信息）。\n\n2) 选择一个“确定会被请求线程调用”的方法作为观察点：\n- 常见：Controller 入口方法、RPC Provider 方法、Filter/Interceptor 的 doFilter/preHandle 等。\n- 避免：高频热点方法（容易刷屏、增加开销）。\n\n## 方案 A：用 watch 直接打印 traceId（最直观）\n\n### A1) 只打印 traceId（最小输出）\n\n```bash\nwatch <类全名> <方法名> '@com.taobao.eagleeye.EagleEye@getTraceId()' -n 5\n```\n\n说明：\n- `@类名@静态方法()` 是 OGNL 静态方法调用语法。\n- `-n 5` 限制执行次数，避免线上刷屏（务必保留/调整）。\n\n### A2) 同时打印参数 + traceId（更好做关联）\n\n```bash\nwatch <类全名> <方法名> '{params, @com.taobao.eagleeye.EagleEye@getTraceId()}' -n 5 -x 2\n```\n\n说明：\n- `{...}` 会以数组/列表方式输出多个字段。\n- `params` 是 Arthas watch 内置变量之一；`-x 2` 控制对象展开深度（可按需调大/调小）。\n\n常见变体（按需）：\n- 在方法返回后再取（默认就是 after，可不写）：\n  - 如果你怀疑 traceId 在方法执行过程中才被设置，可尝试 `-b`（before）对比；具体以线上效果为准。\n\n## 方案 B：用 trace 自动带出 traceId（更适合看调用链）\n\n```bash\ntrace <类全名> <方法名> -n 5\n```\n\n期待现象：\n- `trace` 输出的头部信息里出现类似 `trace_id=<xxxx>` 的字段。\n- 同时你还能看到方法调用链与每段耗时，便于“拿 traceId + 看慢点在哪”一并完成。\n\n## 结果解读与产出（建议模板）\n\n最终给用户的结论/证据建议包含：\n- 观察点（类/方法）：`<类全名>#<方法名>`\n- 获取方式：`watch` / `trace`\n- 关键证据：\n  - `traceId=<...>`（以及必要时的 params 摘要）\n- 下一步建议：\n  - 用该 traceId 去日志/链路系统查询对应请求\n  - 或将观察点收敛到更下游的方法（如某个 DAO/RPC 调用）继续 trace/watch\n\n## 扩展\n\n- 其他分布式追踪系统的 traceId、或 ThreadLocal 里的值，也可以用类似方式在 `watch` 的 OGNL 表达式中读取。\n\n"

    "content": "---\nname: arthas-springcontext-issues-resolve\ndescription: 排查 Spring ApplicationContext / Bean / 配置注入等问题\n---\n\n# Spring Context / Bean 排查指南\n\n原则：\n- **先只读查询**（contains/beanNames/type/environment），避免直接 `getBean()` 触发 Bean 初始化产生副作用。\n- **严格限量**：`vmtool -l` 控制实例数量；避免无条件输出完整 `getBeanDefinitionNames()`。\n\n\n## 1) 获取并挑选正确的 ApplicationContext\n\n优先尝试获取常见的 Spring Boot Context（通常是 `AbstractApplicationContext` 子类）：\n\n```bash\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 5\n```\n\n如果拿不到结果，可以尝试获取： org.springframework.context.ApplicationContext\n\n如果获取到多个对象，可以从对象的 classloader 的 Class<?> name 来判断。\n\n1. 应用的 ClassLoader 通常是包含 `LaunchedURLClassLoader`\n2. 应用的 ClassLoader 绝不会是 com.taobao.pandora.service.loader.ModuleClassLoader\n\n## 2) 获取配置项的值与来源\n\n只看值（示例：`server.port`）：\n\n```bash\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express 'instances[0].getEnvironment().getProperty(\"server.port\")'\n```\n\n获取“来源”\n\n```bash\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express '#env=instances[0].getEnvironment(), #ps=#env.getPropertySources().get(\"configurationProperties\"), #ps.findConfigurationProperty(\"server.port\")'\n```\n\n如果应用有集成 spring-boot-starter-actuator ，可以尝试\n\n```bash\nvmtool --action getInstances \\\n--className org.springframework.boot.actuate.env.EnvironmentEndpoint \\\n--express 'instances[0].environmentEntry(\"server.port\")'\n```\n\n## 3) 按 Bean Name 验证是否存在（不触发初始化）\n\n假设你要查的 beanName 为 `fooService`：\n\n```bash\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express 'instances[0].containsBean(\"fooService\")'\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express 'instances[0].containsLocalBean(\"fooService\")'\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express 'instances[0].containsBeanDefinition(\"fooService\")'\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express 'instances[0].getAliases(\"fooService\")'\n```\n\n判读：\n- `containsBean=true` 但 `containsLocalBean=false`：Bean 可能来自**父 Context**。\n- `containsBean=false` 且你确定应该存在：优先检查**是否选错 Context**、`@Profile/@Conditional`、配置项/环境变量是否生效。\n\n## 4) 在 Spring Context 里“搜” Bean（按关键词过滤，限制输出）\n\n当你只有一个关键词（比如 `order` / `datasource`）而不知道精确 beanName 时：\n\n```bash\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express '#ctx=instances[0], #names=@java.util.Arrays@asList(#ctx.getBeanDefinitionNames()), #m=#names.{? #this.toLowerCase().contains(\"order\")}, #m.subList(0, @java.lang.Math@min(#m.size(), 50))'\n```\n\n说明：\n- 先用关键词把范围收敛，再最多输出 50 个候选；拿到候选 beanName 后回到第 3 步逐个验证。\n\n## 5) 按类型查找 Bean（最适合定位“注入到了哪个实现”）\n\n当你知道目标类型（接口/父类）全限定名时（示例：`com.foo.OrderService`）：\n\n```bash\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express 'instances[0].getBeanNamesForType(@com.foo.OrderService@class)'\n```\n\n若返回多个候选（`NoUniqueBeanDefinitionException` 常见根因），只看候选名称即可：\n\n```bash\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express 'instances[0].getBeansOfType(@com.foo.OrderService@class).keySet()'\n```\n\n提示：\n- 若怀疑代理导致类型不匹配（JDK Proxy / CGLIB），应优先按**接口类型**查询，再决定是否需要获取实例进一步确认。\n- 若 `@com.foo.OrderService@class` 报 `ClassNotFound`，通常是**类加载器不对**：先用 `classloader`（stats/instances/tree）找到应用的 `classLoaderHash`，再在 `vmtool/ognl` 上加 `--classLoader <hash>` 重新执行。也可以找到 `classloader`的 Class Name，再使用 `--classLoaderClass` 参数。\n\n## 6) 查看 BeanDefinition（来源/工厂方法/作用域）\n\n当你需要确认 Bean 是怎么注册进来的（`@Bean` 工厂方法？XML？自动扫描？）时，可尝试拿 `BeanFactory` 看 `BeanDefinition`（前提：Context 是 `AbstractApplicationContext`）。\n\n```bash\nvmtool --action getInstances --className org.springframework.context.support.AbstractApplicationContext -l 1 --express '#ctx=instances[0], #bf=#ctx.getBeanFactory(), #bd=#bf.getBeanDefinition(\"fooService\")'\n```"
