Stefan Podkowinski commented on CASSANDRA-13387:
------------------------------------------------

I think the reason for keeping Cleanup message was for running mixed-version clusters. See
[Yuki's comment|https://issues.apache.org/jira/browse/CASSANDRA-9097?focusedCommentId=14544655&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14544655].

> We're missing metrics for repair, especially for errors. From what I observed now, the
exception will be caught by UncaughtExceptionHandler set in CassandraDaemon and is categorized
as StorageMetrics.exceptions. This is one example:
