stack commented on HBASE-2888:
------------------------------
@Alex 1. and 2. sound great. How would 3. differ from current log? All it has
in it is 'events', no? Regards your question about process, I'd say no need of
an issue per metric., at least not for now. The way it usually runs is we have
a fat umbrella issue like this one, a bunch of work gets done under this
umbrella -- in this case, a bunch of the above will be addressed by the patch
-- but then subsequent amendments or additions get done in separate issues.
Hope this helps.

> 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.
