Kannan Muthukkaruppan commented on HBASE-2888:
----------------------------------------------
Thanks for creating this JIRA.
Some additional comments:
* If the stats, at least the RPC (API-level) stats, could be on a per
Table.ColumnFamily basis, that would be really helpful.
* For non-counter stats, can we always put the "unit" in its name. For example,
storefileIndexSizeMB has MB in its name (which is really useful). But
fsReadLatency doesn't have the units (ms? secs?).

> Project: HBase
> Issue Type: Improvement
> Components: master
> Reporter: Jean-Daniel Cryans
> Fix For: 0.90.0

>
> 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.
