Monitoring

Configure GKE’s monitoring feature via the monitoringConfig field on GCPManagedControlPlane.

GKE enables Google Cloud Managed Service for Prometheus by default on new clusters. You can disable (or explicitly enable) it via monitoringConfig.managedPrometheusConfig:

apiVersion: infrastructure.cluster.x-k8s.io/v1beta1
kind: GCPManagedControlPlane
metadata:
  name: mygcpmanagedcontrolplane
spec:
  monitoringConfig:
    managedPrometheusConfig:
      enabled: false

Setting enabled: false disables Managed Service for Prometheus on the cluster. Setting it to true (or omitting spec.monitoringConfig entirely) leaves GKE’s default behavior in place.

This field is mutable and can be changed on an existing cluster; other monitoring settings GKE manages for the cluster are left untouched.

Note: monitoringConfig cannot be set on Autopilot clusters (source) and trying to set it will cause errors.
