The Docker monitor allows you to monitor statistics about containers. The monitor can connected to a daemon through the url parameter. When home assistant is used within a Docker container, the daemon can be mounted as follows -v /var/run/docker.sock:/var/run/docker.sock.
To use the docker_monitor in your installation, add the following to your configuration.yaml file:
# Example configuration.yaml entry
docker_monitor:
containers:
- homeassistant_homeassistant_1
- homeassistant_mariadb_1
- homeassistant_mosquitto_1
monitored_conditions:
- docker_version
- container_status
- container_memory_usage
- container_memory_percentage_usage
