text: The Monitoring stack is installed with OpenShift Container Platform by default. You can 
  prevent it from being installed by setting 
  openshift_cluster_monitoring_operator_install=False in the Ansible inventory file. 
  
  By default, persistent storage is disabled for Prometheus time-series data and for 
  Alertmanager notifications and silences. You can configure the cluster to persistently store 
  any one of them or both. 
  
  To enable persistent storage of Prometheus time-series data, set 
  openshift_cluster_monitoring_operator_prometheus_storage_enabled=True in the Ansible 
  inventory file. 
  
  To enable persistent storage of Alertmanager notifications and silences, set 
  openshift_cluster_monitoring_operator_alertmanager_storage_enabled=True in the 
  Ansible inventory file. 
  
  To specify the size of the persistent volume claim for Prometheus and Alertmanager, change 
  the following Ansible variables: 
  
  (cid:2) openshift_cluster_monitoring_operator_prometheus_storage_capacity (default: 
  50Gi) 
  (cid:2) 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. 
  
  After you enable dynamic storage, you can also set the storageclass for the persistent 
  volume claim for each component in the Ansible inventory file: 
  
  (cid:2) openshift_cluster_monitoring_operator_prometheus_storage_class_name (default: 
  "") 
  
  (cid:2) openshift_cluster_monitoring_operator_alertmanager_storage_class_name (default: 
  "")
