Subject [jira] [Commented] (KAFKA-6588) Add a metric to monitor live log cleaner thread
Date Sat, 24 Feb 2018 05:34:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-6588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16375316#comment-16375316

James Cheng commented on KAFKA-6588:

KAFKA-3857 added a metric "time-since-last-run-ms". If it's consistently a "small" number,
then the cleaner is still working. If it grows really high, then the log cleaner thread is
dead. PR is here: https://github.com/apache/kafka/pull/1593

Would that be sufficient?

>            Priority: Minor
> We want to have a more direct metric to monitor the log cleaner thread. Hence, adding
a simple metric in `LogCleaner.scala`. 
> Additionally, making a minor change to make sure the correct offsets are logged in `LogCleaner#recordStats`
