PromEx plugin for the Edgehog containers feature.

Exposes the following metric groups:

  • :containers_provisioning_event_metrics exposing, for every resource type provisioned on a device (image deployments, volume deployments, network deployments, device mapping deployments, device request deployments, container deployments and deployments), the provisioning lifecycle:

    • edgehog_containers_provisioning_started_total
    • edgehog_containers_provisioning_completed_total (labeled by result)
    • edgehog_containers_provisioning_duration_seconds (labeled by result)
    • edgehog_containers_provisioning_retries

  • :containers_deployment_event_metrics exposing the end-to-end lifecycle of an application deployment:

    • edgehog_containers_deployment_started_total
    • edgehog_containers_deployment_completed_total (labeled by result)
    • edgehog_containers_deployment_duration_seconds

  • :containers_container_deployment_event_metrics exposing the lifecycle of a single container deployment:

    • edgehog_containers_container_deployment_started_total
    • edgehog_containers_container_deployment_completed_total (labeled by result)
    • edgehog_containers_container_deployment_duration_seconds

The provisioning metrics carry resource_type, result and reason labels, which are low cardinality. Additionally, unless the :containers_telemetry_include_identifiers configuration option is set to false, the metrics also carry the high cardinality identifier labels deployment_id, resource_id and device_id, so that the metrics can be filtered per specific deployment, resource or device in Grafana (e.g. using a dashboard variable resolved to the device ids of a device group).
