Prometheus Config Schema¶

Note

This is auto-generated documentation from a JSON schema that is under construction, this will improve over time.

https://raw.githubusercontent.com/elastisys/compliantkubernetes-apps/main/config/schemas/config.yaml#/properties/prometheus

Configure Prometheus.

Prometheus automatically collects metrics via ServiceMonitors, PodMonitors, and Probes, and pushes metrics to Thanos for long term storage. Additionally Prometheus evaluates recording rules for both service and workload cluster, and all alerting rules for the workload cluster.

Note

Prometheus is installed in both service cluster and workload cluster, so this configuration applies there with some exceptions.
