# 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](https://github.com/rook/rook/blob/master/Documentation/ceph-monitoring.md#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`
|
|
|
|
```bash
|
|
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`
|
|
|
|
```bash
|
|
NAME AGE
|
|
rook-ceph-mgr 14h
|
|
```
|
|
|
|
3. Ensure prometheus rules are present
|
|
|
|
`oc get prometheusrules -l prometheus=rook-prometheus`
|
|
|
|
```bash
|
|
NAME AGE
|
|
prometheus-ceph-rules 14h
|
|
```
