Doc Text:
.The metrics names produced by Ceph exporter and prometheus manager module are the same Previously, the metrics coming from the Ceph daemons (performance counters) were produced by the Prometheus manager module. The new Ceph exporter would replace the Prometheus manager module, and the metrics name produced would not follow the same rules applied in the Prometheus manager module. Due to this, the name of the metrics for the same performance counters were different depending on the provider of the metric (Prometheus manager module or Ceph exporter) With this fix, the Ceph exporter uses the same rules as the ones in the Prometheus manager module to generate metric names from Ceph performance counters. The metrics produced by Ceph exporter and Prometheus manager module are exactly the same.

Description Juan Miguel Olmo 2023-04-13 17:24:46 UTC 
Description of problem:
The metrics coming from daemons perf counters must have the same name if they are exported by the Prometheus manager module or by the Ceph exporter.
Nos we have differences that can cause regression in monitoring tools ( prometheus queries, grafana dashboards...)

6.1

How reproducible:
Compare metrics produced by Mds daemon obtained from prometheus manager module and by and Ceph Exporter
