Andrew Purtell commented on HBASE-625:
--------------------------------------

Just use the gmond xml-over-tcp protocol directly to report metrics to Ganglia?
Also core is getting something working for 0.19.0:

> 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).
