Prometheus monitoring

[Freika]

Added

• Dawarich now can export metrics to Prometheus. You can find the metrics at your.host:9394/metrics endpoint. The metrics are being exported in the Prometheus format and can be scraped by Prometheus server. To enable exporting, set the PROMETHEUS_EXPORTER_ENABLED env var in your docker-compose.yml to true. Example:

  dawarich_app:
    image: freikin/dawarich:latest
    container_name: dawarich_app
    environment:
      ...
      PROMETHEUS_EXPORTER_ENABLED: "true"
