Goal Summary:

Expand the default ACS monitoring suite to include alerting for central-db PVC storage capacity.

While monitoring with OpenShift is enabled by default, ref: https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_security_for_kubernetes/4.8/html/configuring/monitor-acs#monitoring-osp_monitor-acs 

The scope of this alert is currently limited, covering only persistent volumes in the openshift-, kube-, and default namespaces, while central-db PVC resides in a custom namespace (e.g., stackrox or rhacs-operator).

Goals and expected user outcomes:

• Users will receive standard Prometheus alerts when the central-db PVC approaches capacity.
• Expand the existing templates/prometheus.yaml and standard OpenShift monitoring to include alerting on space limits on ACS managed volumes (like central-db PVC).

Acceptance Criteria:

• Predefined Prometheus alerting rules are implemented to trigger when central-db PVC disk usage exceeds defined thresholds.

• Alerts can be deployed automatically.

Success Criteria or KPIs measured:

A list of specific, measurable criteria that will be used to determine if the feature is successful. Include key performance indicators (KPIs) or other metrics., etc. Initial completion during Refinement status.
