[jira] [Commented] (HDDS-11511) OM deletion services should have consistent metrics

    [ https://issues.apache.org/jira/browse/HDDS-11511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17895219#comment-17895219 ] 

Tejaskriya Madhan commented on HDDS-11511:
------------------------------------------

[~erose] I have split the original task into 2: First one being "Introducing metrics in om" and second one being "consistent metrics in scm, om and dn" . The current Jira would track OM metrics only (I have raised a PR already, please do take a look if you can). HDDS-11640 will deal with SCM and DN.

> All background deletion services in Ozone should publish the same set of metrics for each thread:
> * Number of items handled in the last iteration
> ** For OM's directory deleting service, handling of files, empty dirs, and non-empty dirs may be tracked with different metrics.
> ** For services where one DB key is multiple blocks (key delete, SCM block transactions), a separate metric should exist for the number of blocks deleted in the iteration and the number of items processed.
> * Time spent in the last iteration
> Some services may already have these metrics, but some specifically in the OM do not. This Jira should review all the services and fill in these metrics where they are missing.
