Red Hat Bugzilla 2203795 0 unspecified CLOSED ODF Monitoring is missing some of the ceph_* metric values 2023-08-09 17:03:01 UTC

Description Filip Balák 2023-07-31 11:46:04 UTC
Description of problem (please be detailed as possible and provide log
snippests):
In odf 4.13.0-214 was done a change that changed names of some metrics:

ceph_bluestore_submit_lat_sum -> ceph_bluestore_txc_submit_lat_sum
ceph_bluestore_submit_lat_count -> ceph_bluestore_txc_submit_lat_count
ceph_bluestore_throttle_lat_count -> ceph_bluestore_txc_throttle_lat_count
ceph_bluestore_commit_lat_sum -> ceph_bluestore_txc_commit_lat_sum
ceph_bluestore_throttle_lat_sum -> ceph_bluestore_txc_throttle_lat_sum
ceph_bluestore_commit_lat_count -> ceph_bluestore_txc_commit_lat_count

as per https://bugzilla.redhat.com/show_bug.cgi?id=2203795#c35.
In new z-stream version this change is not reflected and those metrics are missing.

Version of all relevant components (if applicable):
ODF 4.13.1-9
OCP 4.13


Steps to Reproduce:
1. Install OCP/ODF cluster
2. After installation, check whether Prometheus provides values for ceph_bluestore_txc_* metrics listed above.

Actual results:
OCP Prometheus provides no values for any of the ceph_bluestore_txc_* metrics listed above.

Expected results:
OCP Prometheus provides values for all ceph_bluestore_txc_* metrics listed above.

Comment 5 Filip Balák 2023-07-31 14:45:03 UTC
Findings in this bug are not relevant because this failed only in external mode where a different version of ceph was used (16.2.10-172). -> CLOSED
