Checkmk Werk 14572: Prometheus: Deprecation of `kube-state-metrics` scrape target

ID: 14572 Title: Prometheus: Deprecation of `kube-state-metrics` scrape target Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The Prometheus agent provides the `kube-state-metrics` as a possible data source. This in turn would enable the following checks. <ul> <li>k8s_resources</li> <li>k8s_namespaces</li> <li>k8s_conditions</li> <li>k8s_pod_container</li> <li>k8s_service_info</li> <li>k8s_daemon_pods</li> </ul> However, these checks are no longer actively maintained, since they have been superseded by their counterparts in the Kubernetes agent.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 <ul> <li>does not support new versions of kube-state-metrics (v2.0.0-alpha / 2020-09-16 or newer),</li> <li>does not provide the information required to fully support monitoring and</li> <li>is stricly inferior to monitoring via the Kubernetes agent.</li> </ul> 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
