The prometheus component exposes metrics in a format which Prometheus can read.

To use the prometheus component in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
prometheus:

The Prometheus component has no configuration variables.

You can then configure Prometheus to fetch metrics from Home Assistant by adding to its scrape_configs configuration.

# Example Prometheus scrape_configs entry
  - job_name: 'hass'
    scrape_interval: 60s
    metrics_path: /api/prometheus
    params:
      api_password: ['PASSWORD']
    scheme: https
    static_configs:
      - targets: ['HOSTNAME:8123']
