If required, you can enable RADOS Block Device (RBD) images monitoring introduced with Ceph Nautilus. Once done, you can view RBD metrics using the Ceph RBD Overview Grafana dashboard. For details, see Ceph dashboards.
To enable RBD monitoring:
Open your Git project repository with the Reclass model on the cluster level.
In classes/cluster/<cluster_name>/ceph/setup.yml add the rbd_stats
