The Prometheus agent provides the kube-state-metrics as a possible data source. This in turn would
enable the following checks.
- k8s_resources
- k8s_namespaces
- k8s_conditions
- k8s_pod_container
- k8s_service_info
- k8s_daemon_pods
However, these checks are no longer actively maintained, since they have been superseded by their
counterparts in the Kubernetes agent. Moreover, the kube-state-metrics target
- does not support new versions of kube-state-metrics (v2.0.0-alpha / 2020-09-16 or newer),
- does not provide the information required to fully support monitoring and
- is stricly inferior to monitoring via the Kubernetes agent.
For this reason, this option will be removed in Checkmk 2.3.0.
If you are affected by this change, you need to setup your monitoring as per these instructions: https://docs.checkmk.com/latest/en/monitoring_kubernetes.html
