Description

Description of problem

The "Client Connection" box has the following issues:
  • It is just MDS/CephFS related (it doesn't show the total number of active connections to the cluster).
  • It's an accumulative counter, so the absolute value is not really meaningful.

Environment

  • ceph version string: all versions

How reproducible

Steps:

Visiting the Ceph-Cluster Grafana Dashboard.

Expected results

A cluster-wide/more meaningful value should be displayed (e.g.: client ops).

As there's no ceph-wide metric for persistent connections, we could replace it with sum((rate(ceph_mon_session_add[15d]))) by (instance) (the 1-min average of new mon sessions)
