Full list of configuration variables

This table contains the full list of the inventory file variables for configuring the Cluster Monitoring Operator:

Table 1. Cluster Monitoring Operator Ansible variables

Variable	Description
openshift_cluster_monitoring_operator_install	Deploy the Cluster Monitoring Operator if true. Otherwise, undeploy. This variable is set to true by default.
openshift_cluster_monitoring_operator_prometheus_storage_capacity	The persistent volume claim size for each of the Prometheus instances. This variable applies only if openshift_cluster_monitoring_operator_prometheus_storage_enabled is set to true. Defaults to 50Gi.
openshift_cluster_monitoring_operator_alertmanager_storage_capacity	The persistent volume claim size for each of the Alertmanager instances. This variable applies only if openshift_cluster_monitoring_operator_alertmanager_storage_enabled is set to true. Defaults to 2Gi.
openshift_cluster_monitoring_operator_node_selector	Set to the desired, existing [node selector] to ensure that pods are placed onto nodes with specific labels. Defaults to node-role.kubernetes.io/infra=true.
openshift_cluster_monitoring_operator_alertmanager_config	Configures Alertmanager.
openshift_cluster_monitoring_operator_prometheus_storage_enabled	Enable persistent storage of Prometheus' time-series data. This variable is set to false by default.
openshift_cluster_monitoring_operator_alertmanager_storage_enabled	Enable persistent storage of Alertmanager notifications and silences. This variable is set to false by default.
openshift_cluster_monitoring_operator_prometheus_storage_class_name	If you enabled the openshift_cluster_monitoring_operator_prometheus_storage_enabled option, set a specific StorageClass to ensure that pods are configured to use the PVC with that storageclass. Defaults to none, which applies the default storage class name.
openshift_cluster_monitoring_operator_alertmanager_storage_class_name	If you enabled the openshift_cluster_monitoring_operator_alertmanager_storage_enabled option, set a specific StorageClass to ensure that pods are configured to use the PVC with that storageclass. Defaults to none, which applies the default storage class name.
