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`
