title: OpenShift Common Issues

Enable Monitoring in the Storage Dashboard

OpenShift Console uses OpenShift Prometheus for monitoring and populating data in Storage Dashboard. Additional configuration is required to monitor the Ceph Cluster from the storage dashboard.

1. Change the monitoring namespace to openshift-monitoring

Change the namespace of the RoleBinding rook-ceph-metrics from rook-ceph to openshift-monitoring for the prometheus-k8s ServiceAccount in rbac.yaml.

subjects:
- kind: ServiceAccount
  name: prometheus-k8s
  namespace: openshift-monitoring

1. Enable Ceph Cluster monitoring

   Follow ceph-monitoring/prometheus-alerts.

2. Set the required label on the namespace

   oc label namespace rook-ceph "openshift.io/cluster-monitoring=true"
   

Troubleshoot Monitoring Issues

!!! attention

Switch to `rook-ceph` namespace using `oc project rook-ceph`.

1. Ensure ceph-mgr pod is Running

   $ oc get pods -l app=rook-ceph-mgr
   NAME            READY   STATUS    RESTARTS   AGE
   rook-ceph-mgr   1/1     Running   0          14h
   

2. Ensure service monitor is present

   $ oc get servicemonitor rook-ceph-mgr
   NAME                          AGE
   rook-ceph-mgr                 14h
   

3. Ensure the prometheus rules object has been created

   $ oc get prometheusrules -l prometheus=rook-prometheus
   NAME                    AGE
   prometheus-ceph-rules   14h
