The Monitoring Stack
The OKD monitoring stack is based on the Prometheus open source project and its wider ecosystem. The monitoring stack includes the following:
Default platform monitoring components. A set of platform monitoring components are installed in the openshift-monitoring project by default during an OKD Container Platform installation. This provides monitoring for core OKD Container Platform components including Kubernetes services. The default monitoring stack also enables remote health monitoring for clusters. These components are illustrated in the Installed by default section in the following diagram.
Components for monitoring user-defined projects. After optionally enabling monitoring for user-defined projects, additional monitoring components are installed in the openshift-user-workload-monitoring project. This provides monitoring for user-defined projects. These components are illustrated in the User section in the following diagram.
