To set up monitoring on a Ceph cluster that has no monitoring, follow the
steps below:
-#. Enable the Prometheus module in the ceph-mgr daemon. This exposes the internal Ceph metrics so that Prometheus can scrape them:
-
- .. prompt:: bash #
-
- ceph mgr module enable prometheus
-
#. Deploy a node-exporter service on every node of the cluster. The node-exporter provides host-level metrics like CPU and memory utilization:
.. prompt:: bash #
