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However, these checks are no longer actively maintained, since they have been superseded by their counterparts in the Kubernetes agent.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.
