# Contributing Guidelines
Thank you for your interest in contributing to our project. Whether it's a bug report, new feature, correction, or additional
documentation, we greatly value feedback and contributions from our community.
Please read through this document before submitting any issues or pull requests to ensure we have all the necessary
information to effectively respond to your bug report or contribution.
## Reporting Bugs/Feature Requests
We welcome you to use the GitHub issue tracker to report bugs or suggest features.
When filing an issue, please check existing open, or recently closed, issues to make sure somebody else hasn't already
reported the issue. Please try to include as much information as you can. Details like these are incredibly useful:
* A reproducible test case or series of steps
* The version of our code being used
* Any modifications you've made relevant to the bug
* Anything unusual about your environment or deployment
## Contributing via Pull Requests
Contributions via pull requests are much appreciated. Before sending us a pull request, please ensure that:
1. You are working against the latest source on the *main* branch.
2. You check existing open, and recently merged, pull requests to make sure someone else hasn't addressed the problem already.
3. You open an issue to discuss any significant work - we would hate for your time to be wasted.
To send us a pull request, please:
1. Fork the repository.
2. Modify the source; please focus on the specific change you are contributing. If you also reformat all the code, it will be hard for us to focus on your change.
3. Ensure local tests pass.
4. Commit to your fork using clear commit messages.
5. Send us a pull request, answering any default questions in the pull request interface.
6. Pay attention to any automated CI failures reported in the pull request, and stay involved in the conversation.
GitHub provides additional document on [forking a repository](https://help.github.com/articles/fork-a-repo/) and

# Configuring an Endpoint
AHA can send to multiple endpoints (webhook URLs, Email or EventBridge). To use any of these you'll need to set it up before-hand as some of these are done on 3rd party websites. We'll go over some of the common ones here.
## Creating a Amazon Chime Webhook URL
**You will need to have access to create a Amazon Chime room and manage webhooks.**
1. Create a new [chat room](https://docs.aws.amazon.com/chime/latest/ug/chime-chat-room.html) for events (i.e. aws_events).
2. In the chat room created in step 1, **click** on the gear icon and **click** *manage webhooks and bots*.
3. **Click** *Add webhook*.
4. **Type** a name for the bot (e.g. AWS Health Bot) and **click** *Create*.
5. **Click** *Copy URL*, we will need it for the deployment.
## Creating a Slack Webhook URL
**You will need to have access to add a new channel and app to your Slack Workspace**.
*Webhook*
1. Create a new [channel](https://slack.com/help/articles/201402297-Create-a-channel) for events (i.e. aws_events)
2. In your browser go to: workspace-name.slack.com/apps where workspace-name is the name of your Slack Workspace.
3. In the search bar, search for: *Incoming Webhooks* and **click** on it.
4. **Click** on *Add to Slack*.
5. From the dropdown **click** on the channel your created in step 1 and **click** *Add Incoming Webhooks integration*.
6. From this page you can change the name of the webhook (i.e. AWS Bot), the icon/emoji to use, etc.
7. For the deployment we will need the *Webhook URL*.
*Workflow*
1. Create a new [channel](https://slack.com/help/articles/201402297-Create-a-channel) for events (i.e. aws_events)
2. Within Slack **click** on your workspace name drop down arrow in the upper left. **click on Tools > Workflow Builder**
3. **Click** Create in the upper right hand corner of the Workflow Builder and give your workflow a name **click** next.
4. **Click** on *select* next to **Webhook** and then **click** *add variable* add the following variables one at a time in the *Key* section. All *data type* will be *text*:
-text
-accounts
-resources
-service
-region
-status
-start_time
-event_arn
-updates
5. When done you should have 9 variables, double check them as they are case sensitive and will be referenced. When checked **click** on *done* and *next*.
6. **Click** on *add step* and then on the add a workflow step **click** *add* next to *send a message*.
7. Under *send this message to:* select the channel you created in Step 1 in *message text* you can should recreate this following:
8. **Click** *save* and the **click** *publish*
9. For the deployment we will need the *Webhook URL*.
## Creating a Microsoft Teams Webhook URL
**You will need to have access to add a new channel and app to your Microsoft Teams channel**.
1. Create a new [channel](https://docs.microsoft.com/en-us/microsoftteams/get-started-with-teams-create-your-first-teams-and-channels) for events (i.e. aws_events)
2. Within your Microsoft Team go to *Apps*
3. In the search bar, search for: *Incoming Webhook* and **click** on it.
4. **Click** on *Add to team*.
5. **Type** in the name of your on the channel your created in step 1 and **click** *Set up a connector*.
6. From this page you can change the name of the webhook (i.e. AWS Bot), the icon/emoji to use, etc. **Click** *Create* when done.
7. For the deployment we will need the webhook *URL* that is presented.
## Configuring an Email
1. You'll be able to send email alerts to one or many addresses. However, you must first [verify](https://docs.aws.amazon.com/ses/latest/DeveloperGuide/verify-email-addresses-procedure.html) the email(s) in the Simple Email Service (SES) console.
2. AHA utilizes Amazon SES so all you need is to enter in a To: address and a From: address.
3. You *may* have to allow a rule in your environment so that the emails don't get labeled as SPAM. This will be something you have to congfigure on your own.
## Creating a Amazon EventBridge Ingestion ARN
**Only required if you are going to be using EventBridge, you can create new with the instructions below or use an existing one**.
1. In the AWS Console, search for **Amazon EventBridge**.
2. On the left hand side, **click** *Event buses*.
3. Under *Custom event* bus **click** *Create event bus*
4. Give your Event bus a name and **click** *Create*.
5. For the deployment we will need the *Name* of the Event bus **(not the ARN, e.g. aha-eb01)**.
# Deployment Options
## Using AWS Health Delegated Administrator with AHA
>NOTE: For users with company restrictions of use/deployment of resources in the organization management account.
>
>On 2023-07-27, AWS Health released the [Delegated Administrator feature](https://docs.aws.amazon.com/health/latest/ug/delegated-administrator-organizational-view.html). By enabling an account as a delegated administrator, you can use AHA in Organization Mode without the need to create and assume the management account IAM role.
To enable this feature:
1. Know the AWS Account ID of your AWS account you want to enable as a delegated administrator for AWS Health (e.g. 123456789012)
1. In the Org Management Account, run the command `aws organizations register-delegated-administrator --account-id ACCOUNT_ID --service-principal health.amazonaws.com` replacing ACCOUNT_ID with the ID of your Member Account
1. Deploy AHA in your deletegated administrator account using the steps for:
1. [AHA for users who ARE using AWS Organizations (CloudFormation)](#aha-with-aws-organizations-on-management-or-delegated-administrator-account-using-cloudformation)
1. [AHA for users who ARE using AWS Organizations (Terraform)](#aha-with-aws-organizations-on-management-or-delegated-administrator-account-using-terraform)
## CloudFormation
There are 3 available ways to deploy AHA, all are done via the same CloudFormation template to make deployment as easy as possible.
The 3 deployment methods for AHA are:
1. [**AHA for users WITHOUT AWS Organizations**](#aha-without-aws-organizations-using-cloudformation): Users NOT using AWS Organizations.
2. [**AHA for users WITH AWS Organizations (Management Account)**](#aha-with-aws-organizations-on-management-or-delegated-administrator-account-using-cloudformation): Users who ARE using AWS Organizations and deploying in the top-level management account.
3. [**AHA for users WITH AWS Organizations (Member Account)**](#aha-with-aws-organizations-on-member-account-using-cloudformation): Users who ARE using AWS Organizations and deploying in a member account in the organization to assume a role in the top-level management account.
## AHA Without AWS Organizations using CloudFormation
### Prerequisites
1. Have at least 1 [endpoint](#configuring-an-endpoint) configured (you can have multiple)
2. Have access to deploy Cloudformation Templates with the following resources: AWS IAM policies, Amazon DynamoDB Tables, AWS Lambda, Amazon EventBridge and AWS Secrets Manager.
3. If using Multi-Region, you must deploy the following 2 CloudFormation templates to allow the Stackset deployment to deploy resources **even if you have full administrator privileges, you still need to follow these steps**.
- In CloudFormation Console create a stack with new resources from the following S3 URL: https://s3.amazonaws.com/cloudformation-stackset-sample-templates-us-east-1/AWSCloudFormationStackSetAdministrationRole.yml - this will allows CFT Stacksets to launch AHA in another region
- Launch the stack.
- In CloudFormation Console create a stack with new resources from the following S3 URL: https://s3.amazonaws.com/cloudformation-stackset-sample-templates-us-east-1/AWSCloudFormationStackSetExecutionRole.yml) - In *AdministratorAccountId* type in the 12 digit account number you're running the solution in (e.g. 000123456789)
- Launch the stack.
### Deployment
1. Clone the AHA package that from this repository. If you're not familiar with the process, [here](https://git-scm.com/docs/git-clone) is some documentation. The URL to clone is in the upper right-hand corner labeled `Clone uri`
2. In the root of this package you'll have two files; `handler.py` and `messagegenerator.py`. Use your tool of choice to zip them both up and name them with a unique name (e.g. aha-v1.8.zip). **Note: Putting the version number in the name will make upgrading AHA seamless.**
3. Upload the .zip you created in Step 1 to an S3 in the same region you plan to deploy this in.
4. In your AWS console go to *CloudFormation*.
5. In the *CloudFormation* console **click** *Create stack > With new resources (standard)*.
6. Under *Template Source* **click** *Upload a template file* and **click** *Choose file* and select `CFN_DEPLOY_AHA.yml` **Click** *Next*.
- In *Stack name* type a stack name (i.e. AHA-Deployment).
- In *AWSOrganizationsEnabled* leave it set to default which is `No`. If you do have AWS Organizations enabled and you want to aggregate across all your accounts, you should be following the steps for [AHA for users who ARE using AWS Organizations (Management Account)](#aha-with-aws-organizations-on-management-or-delegated-administrator-account-using-cloudformation) or [AHA for users WITH AWS Organizations (Member Account)](#aha-with-aws-organizations-on-member-account-using-cloudformation)
- In *AWSHealthEventType* select whether you want to receive *all* event types or *only* issues.
- In *S3Bucket* type ***just*** the bucket name of the S3 bucket used in step 3 (e.g. my-aha-bucket).
- In *S3Key* type ***just*** the name of the .zip file you created in Step 2 (e.g. aha-v1.8.zip).
- In the *Communications Channels* section enter the URLs, Emails and/or ARN of the endpoints you configured previously.
- In the *Email Setup* section enter the From and To Email addresses as well as the Email subject. If you aren't configuring email, just leave it as is.
- In *EventSearchBack* enter in the amount of hours you want to search back for events. Default is 1 hour.
- In *Regions* enter in the regions you want to search for events in. Default is all regions. You can filter for up to 10, comma separated (e.g. us-east-1, us-east-2).
- In *ARN of the AWS Organizations Management Account assume role* leave it set to default None as this is only for customers using AWS Organizations.
- In *Deploy in secondary region?* select another region to deploy AHA in. Otherwise leave to default No.
7. Scroll to the bottom and **click** *Next*.
8. Scroll to the bottom and **click** *Next* again.
9. Scroll to the bottom and **click** the *checkbox* and **click** *Create stack*.
10. Wait until *Status* changes to *CREATE_COMPLETE* (roughly 2-4 minutes or if deploying in a secondary region, it can take up to 30 minutes).

3. Deploy the solution using terraform commands below.
```
$ terraform init
$ terraform plan
$ terraform apply
```
## AHA with AWS Organizations on Management or Delegated Administrator Account using Terraform
1. [Enable Health Organizational View](https://docs.aws.amazon.com/health/latest/ug/enable-organizational-view.html) from the console or CLI, so that you can aggregate Health events for all accounts in your AWS Organization.
2. Have at least 1 [endpoint](#configuring-an-endpoint) configured (you can have multiple)
**NOTE: ** For Multi region deployment, DynamoDB table will be created with PAY_PER_REQUEST billing mode insted of PROVISIONED due to limitation with terraform.
### Deployment - Terraform
1. Clone the AHA package that from this repository. If you're not familiar with the process, [here](https://git-scm.com/docs/git-clone) is some documentation. The URL to clone is in the upper right-hand corner labeled `Clone uri`
```
$ git clone https://github.com/aws-samples/aws-health-aware.git
$ cd aws-health-aware/terraform/Terraform_DEPLOY_AHA
```
5. Update parameters file **terraform.tfvars** as below
- *aha_primary_region* - change to region where you want to deploy AHA solution
- *aha_secondary_region* - Required if needed to deploy in AHA solution in multiple regions, change to another region (Secondary) where you want to deploy AHA solution, Otherwise leave to default empty value.
- *AWSOrganizationsEnabled* - change the value to `Yes`. If you do NOT have AWS Organizations enabled you should be following the steps for [AHA for users who are NOT using AWS Organizations](#aha-without-aws-organizations-using-terraform)
- *AWSHealthEventType* - select whether you want to receive *all* event types or *only* issues.
- *Communications Channels* section - enter the URLs, Emails and/or ARN of the endpoints you configured previously.
- *Email Setup* section - enter the From and To Email addresses as well as the Email subject. If you aren't configuring email, just leave it as is.
- *EventSearchBack* - enter in the amount of hours you want to search back for events. Default is 1 hour.
- *Regions* enter in the regions you want to search for events in. Default is all regions. You can filter for up to 10, comma separated (e.g. us-east-1, us-east-2).
- *ManagementAccountRoleArn* - Leave it default empty value
- *S3Bucket* - type ***just*** the name of the S3 bucket where exclude file .csv you upload. leave it empty if exclude Account feature is not used.
- *ExcludeAccountIDs* - type ***just*** the name of the .csv file you want to upload if needed to exclude accounts from monitoring, else leave it to empty.
- *ManagementAccountRoleArn* - In ARN of the AWS Organizations Management Account assume role leave it set to default None, unless you are using a member account instead of the management account. Instructions for this configuration are in the next section.
3. Deploy the solution using terraform commands below.
```
$ terraform init
$ terraform plan
$ terraform apply
```
## AHA WITH AWS Organizations on Member Account using Terraform
> Note: On 2023-07-27, AWS Health released the Delegated Admin feature which enables AHA deployments in member accounts without the extra steps below.
See: [Using AWS Health Delegated Administrator with AHA](#using-aws-health-delegated-administrator-with-aha)
1. [Enable Health Organizational View](https://docs.aws.amazon.com/health/latest/ug/enable-organizational-view.html) from the console or CLI, so that you can aggregate Health events for all accounts in your AWS Organization.
2. Have at least 1 [endpoint](#configuring-an-endpoint) configured (you can have multiple)
**NOTE: ** For Multi region deployment, DynamoDB table will be created with PAY_PER_REQUEST billing mode insted of PROVISIONED due to limitation with terraform.
### Deployment - Terraform
1. Clone the AHA package that from this repository. If you're not familiar with the process, [here](https://git-scm.com/docs/git-clone) is some documentation. The URL to clone is in the upper right-hand corner labeled `Clone uri`
```
$ git clone https://github.com/aws-samples/aws-health-aware.git
```
2. In your top-level management account deploy terraform module Terraform_MGMT_ROLE.tf to create Cross-Account Role for PHD access
```
$ cd aws-health-aware/terraform/Terraform_MGMT_ROLE
$ terraform init
$ terraform plan
$ terraform apply
Input *OrgMemberAccountId* Enter the account id of the member account you plan to run AHA in (e.g. 000123456789).
```
3. Wait for deployment to complete. This will create an IAM role with the necessary AWS Organizations and AWS Health API permissions for the member account to assume. and note the **AWSHealthAwareRoleForPHDEventsArn** role name, this will be used during deploying solution in member account
4. In the *Outputs* section, there will be a value for *AWSHealthAwareRoleForPHDEventsArn* (e.g. arn:aws:iam::000123456789:role/aha-org-role-AWSHealthAwareRoleForPHDEvents-ABCSDE12201), copy that down as you will need to update params file (variable ManagementAccountRoleArn).
4. Change directory to **terraform/Terraform_DEPLOY_AHA** to deploy the solution
5. Update parameters file **terraform.tfvars** as below
- *aha_primary_region* - change to region where you want to deploy AHA solution
- *aha_secondary_region* - Required if needed to deploy in AHA solution in multiple regions, change to another region (Secondary) where you want to deploy AHA solution, Otherwise leave to default empty value.
- *AWSOrganizationsEnabled* - change the value to `Yes`. If you do NOT have AWS Organizations enabled you should be following the steps for [AHA for users who are NOT using AWS Organizations](#aha-without-aws-organizations-using-terraform)
- *AWSHealthEventType* - select whether you want to receive *all* event types or *only* issues.
- *Communications Channels* section - enter the URLs, Emails and/or ARN of the endpoints you configured previously.
- *Email Setup* section - enter the From and To Email addresses as well as the Email subject. If you aren't configuring email, just leave it as is.
- *EventSearchBack* - enter in the amount of hours you want to search back for events. Default is 1 hour.
- *Regions* enter in the regions you want to search for events in. Default is all regions. You can filter for up to 10, comma separated (e.g. us-east-1, us-east-2).
- *ManagementAccountRoleArn* - Enter in the full IAM arn from step 10 (e.g. arn:aws:iam::000123456789:role/aha-org-role-AWSHealthAwareRoleForPHDEvents-ABCSDE12201)
- *S3Bucket* - type ***just*** the name of the S3 bucket where exclude file .csv you upload. leave it empty if exclude Account feature is not used.
- *ExcludeAccountIDs* - type ***just*** the name of the .csv file you want to upload if needed to exclude accounts from monitoring, else leave it to empty.
4. Deploy the solution using terraform commands below.
```
$ terraform init
$ terraform plan
$ terraform apply
```
# Updating using CloudFormation
**Until this project is migrated to the AWS Serverless Application Model (SAM), updates will have to be done as described below:**
1. Download the updated CloudFormation Template .yml file and 2 `.py` files.
2. Zip up the 2 `.py` files and name the .zip with a different version number than before (e.g. if the .zip you originally uploaded is aha-v1.8.zip the new one should be aha-v1.9.zip)
3. In the AWS CloudFormation console **click** on the name of your stack, then **click** *Update*.
4. In the *Prepare template* section **click** *Replace current template*, **click** *Upload a template file*, **click** *Choose file*, select the newer `CFN_DEPLOY_AHA.yml` file you downloaded and finally **click** *Next*.
5. In the *S3Key* text box change the version number in the name of the .zip to match name of the .zip you uploaded in Step 2 (The name of the .zip has to be different for CloudFormation to recognize a change). **Click** *Next*.
6. At the next screen **click** *Next* and finally **click** *Update stack*. This will now upgrade your environment to the latest version you downloaded.
**If for some reason, you still have issues after updating, you can easily just delete the stack and redeploy. The infrastructure can be destroyed and rebuilt within minutes through CloudFormation.**
# Updating using Terraform
**Until this project is migrated to the AWS Serverless Application Model (SAM), updates will have to be done as described below:**
1. Pull the latest code from git repository for AHA.
2. Update the parameters file terraform.tfvars per your requirement
3. Copy the terraform template files to directory where your previous state exists
4. Deploy the templates as below
```
$ cd aws-health-aware
$ git pull https://github.com/aws-samples/aws-health-aware.git
$ cd terraform/Terraform_DEPLOY_AHA
$ terraform init
$ terraform plan - This command should show any difference existing config and latest code.
$ terraform apply
```
**If for some reason, you still have issues after updating, you can easily just delete the stack and redeploy. The infrastructure can be destroyed and rebuilt within minutes through Terraform.**
# New Features
*Release 2.2*
We are happy to announce the launch of new enhancements to AHA. Please try them out and keep sending us your feedback!
1. A revised schema for AHA events sent to EventBridge which enables new filtering and routing options. See the [new AHA event schema readme](new_aha_event_schema.md) for more detail.
2. Multi-region deployment option
3. Updated file names for improved clarity
4. Ability to filter accounts (Refer to AccountIDs CFN parameter for more info on how to exclude accounts from AHA notifications)
4. Ability to view Account Names for a given Account ID in the PHD alerts
5. If you are running AHA with the Non-Org mode, AHA will send the Account #' and resource(s) impacts if applicable for a given alert
6. Ability to deploy AHA with the Org mode on a member account
7. Support for a new Health Event Type - "Investigation"
8. Terraform support to deploy the solution
# Troubleshooting
* If for whatever reason you need to update the Webhook URL; just update the CloudFormation or terraform Template with the new Webhook URL.
* If you are expecting an event and it did not show up it may be an oddly formed event. Take a look at *CloudWatch > Log groups* and search for the name of your Lambda function. See what the error is and reach out to us [email](mailto:aha-builders@amazon.com) for help.
* If for any errors related to duplicate secrets during deployment, try deleting manually and redeploy the solution. Example command to delete SlackChannelID secret in us-east-1 region.
```
$ aws secretsmanager delete-secret --secret-id SlackChannelID --force-delete-without-recovery --region us-east-1
```
* If you want to Exclude certain accounts from notifications, confirm your exlcusions file matches the format of the [sample ExcludeAccountIDs.csv file](ExcludeAccountIDs(sample).csv) with one account ID per line with no trailing commas (trailing commas indicate a null cell).
* If your accounts listed in the CSV file are not excluded, check the CloudWatch log group for the AHA Lambda function for the message "Key filename is not a .csv file" as an indicator of any issues with your file.

# Readme for new AHA Event schema
## New AHA Event Schema
With release X.Y.Z, AHA includes an updated format for events published to EventBridge. Building on the [existing event format](https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/EventTypes.html#health-event-types) published by AWS Health, AHA enriches it with additional data from the Health API and AWS Organizations to enable new options for filtering in EventBridge.
>Note: If you used the previous { "title": "Title", "value": "Value" } schema in your rules, you must update your rules to reflect the new schema when deploying the new version of AHA
### Schema:
```

"version": "0",

}]
}
}
```
### AHA added properties
**eventScopeCode:** Specifies if the Health event is a public AWS service event or an account-specific event.
Values: *string -* `PUBLIC | ACCOUNT_SPECIFIC`
**statusCode:** Reflects whether the event is ongoing, resolved or in the case of scheduled maintenance, upcoming.
Values: *string -* `open | closed | upcoming`
**affectedEntities:** For ACCOUNT_SPECIFIC events, AHA includes expanded detail on resources. **affectedEntities** includes the listed **resources**, each as an **entitityValue** with the resource ID (as it appears in events for single accounts). AHA adds the related **awsAccountId** and In AWS Organizations, **awsAccountName** of the resource.
Values: *entity object(s). May be empty if no resources are listed*
## EventBridge pattern examples
As a primer we recommended you review the [EventBridge EventPatterns](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-patterns.html) documentation and examples on [Content filtering in Amazon EventBridge event patterns](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-patterns-content-based-filtering.html)
Use the following sample event published by AWS Health Aware to test matching in the provided examples:
```
{
"version": "0",
"id": "e47c4390-b295-ce6f-7e94-f13083d7bb90",
"detail-type": "AHA Event",
"source": "aha",
"account": "`234567890123`",
"time": "2022-07-20T18:26:17Z",
"region": "us-east-1",
"resources": [
"vpn-0d0e3eeefe6aabb0d"
],
"detail": {
"arn": "arn:aws:health:us-east-1::event/VPN/AWS_VPN_REDUNDANCY_LOSS/AWS_VPN_REDUNDANCY_LOSS-1656151378267-7672191-IAD",
"service": "VPN",
"eventTypeCode": "AWS_VPN_REDUNDANCY_LOSS",
"eventTypeCategory": "accountNotification",
"region": "us-east-1",
"startTime": "2022-06-25 10:00:48.868000+00:00",
"lastUpdatedTime": "2022-06-25 10:02:58.371000+00:00",
"statusCode": "open",
"eventScopeCode": "ACCOUNT_SPECIFIC",
"eventDescription": {
"latestDescription": "Your VPN Connection associated with this event in the us-east-1 Region had a momentary lapse of redundancy as one of two tunnel endpoints was replaced. Connectivity on the second tunnel was not affected during this time. Both tunnels are now operating normally.\n\nReplacements can occur for several reasons, including health, software upgrades, customer-initiated modifications, and when underlying hardware is retired. If you have configured your VPN Customer Gateway to use both tunnels, then your VPN Connection will have utilized the alternate tunnel during the replacement process. For more on tunnel endpoint replacements, please see our documentation [1].\n\nIf you have not configured your VPN Customer Gateway to use both tunnels, then your VPN Connection may have been interrupted during the replacement. We encourage you to configure your router to use both tunnels. You can obtain the VPN Connection configuration recommendations for several types of VPN devices from the AWS Management Console [2]. On the \"Amazon VPC\" tab, select \"VPN Connections\". Then highlight the VPN Connection and choose \"Download Configuration\".\n\n[1] https://docs.aws.amazon.com/vpn/latest/s2svpn/monitoring-vpn-health-events.html\n[2] https://console.aws.amazon.com"
},
"affectedEntities": [{
"entityValue": "vpn-0d0e3eeefe6aabb0d",
"awsAccountId": "987654321987",
"awsAccountName": "Prod-Apps"
}]
}
}
```
To write a rule that matches resources found in the event, reference the **resources** key of the JSON event, and provide an event pattern to the EventBridge rule. Example 1 matches on an exact resource - “*vpn-0d0e3eeefe6aabb0d*”. Example 2 matches any resource starting with "*vpn-*"
**Example 1:**
```
{
"resources": [
"vpn-0d0e3eeefe6aabb0d"
]
}
```
**Example 2:**
```
{
"resources": [
{"prefix": "vpn-"}
]
}
```
To match based on a specific service, note that **service** is nested within the **detail** key in the JSON structure, so we reference both **detail** and **service**. Example 3 matches the VPN service, and Example 4 matches EC2 OR S3 (will not match the sample event). To get a list of all service names used by AWS Health you can use the cli command - `aws health describe-event-types`
**Example 3:**
```
{
"detail": {
"service": ["VPN"]
}
}
```
**Example 4:**
```
{
"detail": {
"service": ["EC2", "S3"]
}
}
```
To match events based on an AWS account name or number, use the following patterns. Take note of the additional levels of nesting based on the sample event. Example 5 matches a specific account number as **awsAccountId**. Example 6 matches a specific account name, and Example 7 adds an additional field of **eventTypeCategory** along with the “prefix” filter pattern which will match any value in the **awsAccountName** field that starts with “*Prod*” similar to a wildcard match of “*Prod**”
**Example 5:**
```
{
"detail": {
"affectedEntities": {
"awsAccountId": ["987654321987"]
}
}
}
```
**Example 6:**
```
{
"detail": {
"affectedEntities": {
"awsAccountName": ["Prod-Apps"]
}
}
}
```
**Example 7:**
```
{
"detail": {
"eventTypeCategory": ["accountNotification"],
"affectedEntities": {
"awsAccountName": [{"prefix": "Prod"}]
}
}
}
```
Combine any of the patterns listed to create more specific rules. Note that all patterns in the rule must match for the EventBridge rule to trigger. Example 8 will only match when all 3 conditions exist in an AHA event - **service** = *VPN*, **region** = *us-east-1* and **awsAccountId** = *987654321098*
**Example 8:**
```
{
"detail": {
"service": ["VPN"],
"region": ["us-east-1"],
"affectedEntities": {
"awsAccountId": ["987654321987"]
}
}
}
```
As a best practice, also include `"source": ["aha"]` in your pattern if the event bus contains events generated by other sources.
**Example 9:**
```
{
"source": ["aha"],
"detail": {
"service": ["VPN"],
"region": ["us-east-1"],
"affectedEntities": {
"awsAccountId": ["987654321987"]
}
}
}
```
