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.

   yamlCopy

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

2. Enable Ceph Cluster monitoring

   Follow ceph-monitoring/prometheus-alerts.

3. Set the required label on the namespace

   consoleCopy

   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

   consoleCopy

   $ 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

   consoleCopy

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

3. Ensure the prometheus rules object has been created

   consoleCopy

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