ceph mgr module enable prometheus
ceph-exporter
=============
``ceph-exporter`` works alongside the Prometheus manager module. The two
components have distinct responsibilities:
- The **Prometheus manager module** exposes all cluster-level metrics by
default other than Ceph daemon performance counters. However, these metrics
may be exported by the Prometheus manager module by setting the module option
:confval:`mgr/prometheus/exclude_perf_counter` to `false`.
- The **ceph-exporter daemon** exposes only Ceph daemon performance counters
as Prometheus metrics, running on each host in the cluster.
