stack updated HBASE-625:
------------------------
Attachment: metrics.patch
Here's a basic patch. Needs more stats added. Just does regionserver at
moment. Also need to make sure that when master and regionserver on same
machine they don't clash. Also adds jvm monitoring so can see jvm stats up in
ganglia too.
See
http://hadoop.apache.org/core/docs/r0.18.1/api/org/apache/hadoop/metrics/package-summary.html#package_description
for howto on metrics.

>
> hbase should write loadings on a period in a format that is amenable to tools
> like ganglia (rrd). Master can dump cluster loadings and averages.
> Regionservers would report their own loadings. Should exploit the work up in
> hadoop for doing this kinda thing (GangliaContext) where it makes sense.
> Extra browning points if user can optionally enable display of graphs in the
> hbase UI (JRobin).
