stack commented on HBASE-5788:
------------------------------
bq. TestRegionServerMetrics covers most of the functionality of the new class
but I can create a new set of more explicit tests if you think that is needed.
Probably no need if we have some coverage already. Just want to make sure the
class does its basic contract. Easier figuring this stuff in a unit test than
up on a cluster, yadda, yadda, you know what I'm at.
> Move Dynamic Metrics storage off of HRegion.

> HRegion right now has the responsibility of storing static counts and latency
> numbers for use by the metrics package. Since these maps are incremented and
> set from lots of places it makes adding functionality hard.
>
> So move the metrics functionality into SchemaMetrics making it more than just
> a class for naming. The next step will be to simplify the api exposed so
> that using it will be easier.
