Glances is a cross-platform monitoring tool developed by [@nicolargo](https://github.com/nicolargo). It's similar to top/htop but with a [Rest API](https://glances.readthedocs.io/en/latest/api.html) and many [data exporters](https://glances.readthedocs.io/en/latest/gw/index.html) available. Under the hood, it uses [psutil](https://github.com/giampaolo/psutil) for retrieving system info.
If you don't already have it installed, either follow the [Installation Guide](https://github.com/nicolargo/glances/blob/master/README.rst) for your system, or setup [with Docker](https://glances.readthedocs.io/en/latest/docker.html), or use the one-line install script: `curl -L https://bit.ly/glances | /bin/bash`. You'll need to run Glances as a web server, using the `-w` option, see the [command reference docs](https://glances.readthedocs.io/en/latest/cmds.html) for more info.

Glances can be launched with the `glances` command. You'll need to run it in web server mode, using the `-w` option for the API to be reachable. If you don't plan on using the Web UI, then you can disable it using `--disable-webui`. See the [command reference docs](https://glances.readthedocs.io/en/latest/cmds.html) for more info.

### System Load History
Shows recent historical system load, calculated from the number of processes waiting in the run-queue, in 1, 5 and 15 minute intervals, and averaged across all cores. Optionally specify `limit` to set number of results returned, defaults to `500`, max `100000`, but the higher the number the longer the load and render times will be.

### Widget Styling
Like elsewhere in Dashy, all colours can be easily modified with CSS variables.
Widgets use the following color variables, which can be overridden if desired:
- `--widget-text-color` - Text color, defaults to `--primary`
- `--widget-background-color` - Background color, defaults to `--background-darker`
- `--widget-accent-color` - Accent color, defaults to `--background`
For more info on how to apply custom variables, see the [Theming Docs](/docs/theming.md#setting-custom-css-in-the-ui)

### Proxying Requests
If a widget fails to make a data request, and the console shows a CORS error, this means the server is blocking client-side requests.

### Customizing Charts
For widgets that contain charts, you can set an array of colors under `chartColors`. To specify the chart height, set `chartHeight` to an integer (in `px`), defaults to `300`. For example:
```yaml
- type: gl-load-history
options:
hostname: http://192.168.130.2:61208
chartColors: ['#9b5de5', '#f15bb5', '#00bbf9', '#00f5d4']
chartHeight: 450
```

### Language Translations
Since most of the content displayed within widgets is fetched from an external API, unless that API supports multiple languages, translating dynamic content is not possible.
