Cluster health recommendations
From Red Hat Hybrid Cloud Console, you can use the Red Hat Lightspeed advisor service to assess and monitor the health of your OpenShift Container Platform clusters.
The Lightspeed advisor service checks your OpenShift Container Platform clusters against Red Hat best practices and highlights service availability, fault tolerance, performance, and security risks. Its recommendations help you avoid potential problems or solve problems quickly without unplanned downtime.
Each recommendation describes a detected issue, its total risk, the affected clusters, and, where applicable, steps to resolve the issue.
To use the Lightspeed advisor service, register your clusters with OpenShift Cluster Manager.
