-------------------------------
Fix Version/s: (was: 0.11.0.0)
> Export buffer cache metrics in JMX
> ----------------------------------
>
> Key: KAFKA-4838
> URL: https://issues.apache.org/jira/browse/KAFKA-4838
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Affects Versions: 0.10.2.0
> Reporter: Eno Thereska
> Priority: Minor
> Labels: needs-kip
>
> Currently we log certain cache metrics, but don't export those via JMX, e.g.,
> in ThreadCache.flush() we have:
> log.debug("Thread {} cache stats on flush: #puts={}, #gets={}, #evicts={},
> #flushes={}",name, puts(), gets(), evicts(), flushes());
> We should export the hits, misses etc as metrics (with a DEBUG recording
> level).
