[jira] [Commented] (CASSANDRA-15661) Improve logging by using more
appropriate levels
[ https://issues.apache.org/jira/browse/CASSANDRA-15661?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17067835#comment-17067835 ]
Jon Haddad commented on CASSANDRA-15661:
----------------------------------------
I'll have Jenkins test results here as soon as I'm able to run unit + dtests. ATM the new jenkins setup is failing my builds and CircleCI bombs out when running dtests on medium instances. I can't think of a reason why unit tests would break, but dtests might be relying on logs at a specific level. Hopefully I can get the CI results posted today.

> There are a number of log statements using logging levels that are a bit too conservative. For example:
> * Flushing memtables is currently at debug. This is a relatively rare event that is important enough to be INFO
> * When compaction finishes we log the progress at debug
> * Different steps in incremental repair are logged as debug, should be INFO
> * when reaching connection limits in ConnectionLimitHandler.java we log at warn rather than error. Since this is a client disconnect it’s more than a warning, we’re taking action and disconnecting.
