Chapter 3. Alerts

For internal Mode clusters, various alerts related to the storage metrics services, storage cluster, disk devices, cluster health, cluster capacity, and so on are displayed in the Block and File, and the object dashboards. These alerts are not available for external Mode.

You can also view alerts with additional details and customize the display of Alerts in the OpenShift Container Platform.

For more information, see Managing alerts.

Overprovision control is a mechanism that allows administrators to define a quota on the amount of PVCs consumed from a storage cluster, as per the specific application namespace. When you enable overprovision it prevents you from overprovisioning the PVCs. OpenShift provides a flexibility for defining constraints that limit the aggregated resource consumption at cluster scope with the help of OpenShift’s ClusterResourceQuota. With Overprovision control, ClusteResourceQuota is initiated and administrators can set the limit for consumed storage capacity per storage-class. The alarm then triggers at 80% of the capacity limit of the PVC.
