# 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](https://github.com/rook/rook/blob/master/cluster/examples/kubernetes/ceph/monitoring/rbac.yaml#L70).
```
subjects:
- kind: ServiceAccount
name: prometheus-k8s
namespace: openshift-monitoring
```
2. Enable Ceph Cluster monitoring
Follow [ceph-monitoring/prometheus-alerts](ceph-monitoring.md#prometheus-alerts).
3. 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
```
