The Cluster Monitoring Operator manages and updates the Prometheus-based cluster monitoring stack deployed on top of OpenShift.
It contains the following components:
The deployed Prometheus instance (prometheus-k8s) is responsible for monitoring and alerting on cluster and OpenShift components; it should not be extended to monitor user applications. Users interested in leveraging Prometheus for application monitoring on OpenShift should consider enabling User Workload Monitoring to easily setup new Prometheus instances to monitor and alert on their applications.
Alertmanager is a cluster-global component for handling alerts generated by all Prometheus instances deployed in that cluster.
See the Sending metrics via Telemetry page.
