## System Resource Monitoring
|
||||
|
||||
The easiest method for displaying system info and resource usage in Dashy is with [Glances](https://nicolargo.github.io/glances/).
|
||||
|
||||
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.
|
||||
|
||||
|
||||
