-----------------------------------------
+1 for emitting events and letting other systems store/render them.
> Review all our metrics

> Key: HBASE-2888
> URL: https://issues.apache.org/jira/browse/HBASE-2888
> Project: HBase
> Issue Type: Improvement
> Components: master
> Reporter: Jean-Daniel Cryans
> Fix For: 0.92.0
>
>
> HBase publishes a bunch of metrics, some useful some wasteful, that should be
> improved to deliver a better ops experience. Examples:
> - Block cache hit ratio converges at some point and stops moving
> - fsReadLatency goes down when compactions are running
> - storefileIndexSizeMB is the exact same number once a system is serving
> production load
> We could use new metrics too.
