Description Aashish sharma 2022-07-18 12:38:33 UTC

Description of problem:We would like to have "Different Storage Class" metrics in Prometheus dashboard. Prometheus already provide below metrics for the overall cluster:

~~~
ceph_cluster_total_bytes
ceph_cluster_total_used_bytes
ceph_cluster_total_used_raw_bytes
~~~

We would also like to get different storage class metrics, for example if I have 2 classes Slowerclass and fasterclass, then I should be able to get below metrics:

~~~
Slowerclass_bytes
Slowerclass_used_bytes
Slowerclass_used_raw_bytes
fasterclass_bytes
fasterclass_used_bytes
fasterclass_used_raw_bytes

Comment 2 Aashish sharma 2022-07-19 05:36:14 UTC

Hi Vikhyat,

Thank you for providing this useful information. Ernesto has created a design doc for the implementation of this feature request https://docs.google.com/document/d/1trnz8VXP1rDMs0glEAtOfLZcpH0coqdJwVkF2ihQITE/edit#heading=h.edvemstuogz2 . Moreover from the info provided by you and this doc, it seems that we have the required metrics in place , hence I will close this bugzilla. 

Thanks & Regards
Aashish
