Home Assistant

Glances

The glances sensor platform is consuming the system information provided by the Glances API. This enables one to track remote host and display their stats in Home Assistant.

This sensors needs a running instance of glances on the host. The minimal supported version of glances is 2.3. To start a Glances RESTful API server on its default port 61208, the a test the following command can be used:

$ sudo glances -w
Glances web server started on http://0.0.0.0:61208/

Check if you are able to access the API located at http://IP_ADRRESS:61208/api/2. Don’t use -s as this will start the XMLRPC server on port 61209. Home Assistant only supports the REST API of GLANCES.

The details about your memory usage is provided as a JSON response. If so, you are good to proceed.

$ curl -X GET http://IP_ADDRESS:61208/api/2/mem/free
{"free": 203943936}

For details about auto-starting glances, please refer to Start Glances through Systemd.

To enable the Glances sensor, add the following lines to your configuration.yaml:

# Example configuration.yaml entry
sensor:
  - platform: glances
    host: IP_ADDRESS
    resources:
      - 'disk_use_percent'
      - 'disk_use'
      - 'disk_free'
      - 'memory_use_percent'
      - 'memory_use'
      - 'memory_free'
      - 'swap_use_percent'
      - 'swap_use'
      - 'swap_free'
      - 'processor_load'
      - 'process_running'
      - 'process_total'
      - 'process_thread'
      - 'process_sleeping'
      - 'cpu_temp'

Configuration variables:

  • host (Required): The IP address of your host, eg. 192.168.1.32.
  • port (Option): The network port to connect to. Default is 61208.
  • name (Optional): Name of the Glances sensor.
  • resources (Required): Entries to monitor.
    • disk_use_percent: Used disk space in percent
    • disk_use: Used disk space
    • disk_free: Free disk space
    • memory_use_percent: Used memory in percent
    • memory_use: Used memory
    • memory_free: Free memory
    • swap_use_percent: Used swap space in percent
    • swap_use: Used swap space
    • swap_free: Free swap space
    • processor_load: Load
    • process_running: Number of running processes
    • process_total: Total number of processes
    • process_thread: Number of threads
    • process_sleeping: Number of sleeping processes
    • cpu_temp: CPU Temperature (may not available on all platforms)

Not all platforms are able to provide all metrics. For instance cpu_temp is requires installing and configuring lmsensors in Ubuntu, and may not be available at all in other platforms.
