> gtop - System monitoring dashboard for terminal

## SYNOPSIS

`gtop`


## DESCRIPTION

gtop is a system monitoring dashboard for terminal much like htop, top, etc...

## INTERACTIVE COMMANDS

The following commands are supported while in gtop:

- `p` sort the process table by Process Id
- `c` sort the process table by CPU usage
- `m` sort the process table by Memory usage

### Requirements

* Linux / OSX / Windows (partial support)
* Node.js >= v8

### Installation

```sh
$ npm install gtop -g
```

#### Docker

You need to assign host `net` and `pid` to access the metrics in the host machine.

```sh
$ docker run --rm -it \
    --name gtop \
    --net="host" \
    --pid="host" \
    aksakalli/gtop
```

### Usage

Start gtop with the `gtop` command

```sh
$ gtop
```

To stop gtop use `q`, or `ctrl+c` in most shell environments.

You can sort the process table by pressing

* `p`: Process Id
* `c`: CPU usage
* `m`: Memory usage

### Troubleshooting

If you see question marks or other different characters, try to run it with these environment variables:

```sh
$ LANG=en_US.utf8 TERM=xterm-256color gtop
```
