Setting persistent storage size

You can specify the size of the persistent volume claim for Prometheus and Alertmanager.

Procedure

Change these Ansible variables:
- openshift_cluster_monitoring_operator_prometheus_storage_capacity (default: 50Gi)
- openshift_cluster_monitoring_operator_alertmanager_storage_capacity (default: 2Gi)
Each of these variables applies only if its corresponding storage_enabled variable is set to true.
