Prometheus Monitoring

Each Rook Ceph cluster has some built in metrics collectors/exporters for monitoring with Prometheus. If you do not have Prometheus running, follow the steps presented here, to enable monitoring of Rook.

With the Prometheus operator running, we can create a service monitor that will watch the Rook cluster and collect metrics regularly. From the root of your locally cloned Rook repo, go the monitoring directory

$ cd rook/cluster/examples/kubernetes/ceph/monitoring
$ kubectl create -f service-monitor.yaml
$ kubectl create -f prometheus.yaml
$ kubectl create -f prometheus-service.yaml
# Ensure that the Prometheus server pod gets created and advances to the Running state before moving on
$ kubectl -n rook-ceph get pod prometheus-rook-prometheus-0

Once the Prometheus server is running, you can open a web browser and go http://<VM_FIP>:<port>. In the prometheus-service.yaml file the nodePort parameter is set by default to 30900. Obviously you can customize this value and remember to open the chosen port on OpenStack.
