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. 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

Pre-req: Switch to rook-ceph namespace with oc project rook-ceph

  1. Ensure ceph-mgr pod is Running

    $ oc get pods -l app=rook-ceph-mgr

    1.  NAME            READY   STATUS    RESTARTS   AGE
    2.  rook-ceph-mgr   1/1     Running   0          14h

  2. Ensure service monitor is present

    $ oc get servicemonitor rook-ceph-mgr

    1.  NAME                          AGE
    2.  rook-ceph-mgr                 14h

  3. Ensure prometheus rules are present

    oc get prometheusrules -l prometheus=rook-prometheus

    1.  NAME                    AGE
    2.  prometheus-ceph-rules   14h
