Josh Elser commented on ACCUMULO-1817:
--------------------------------------
One big question that needs to be addressed here is what to do with the
existing accumulo-metrics.xml file. Metrics2 expects a
hadoop-metrics2*.properties file to be configure the sources (emitters from
Accumulo) and sinks (file-based logging, push to Ganglia, etc).
I think, long term, it would be better to solely move to the properties file
(standardize on what's going on upstream), but that would cause a little bit of
pain for users who expect to configure/control metrics via accumulo-metrics.xml.
Thoughts anyone?

> We currently expose JMX and it's possible (with external code) to bridge the
> JMX to solutions like Ganglia. It would be ideal if the integration were
> native and pluggable.
> Turns out that Hadoop (hdfs, mapred) and HBase has "direct" metrics reporting
> to Ganglia through some nice code provided in Hadoop.
> Look into the GangliaContext to see if we can implement Ganglia metrics
> reporting by Accumulo configuration alone.
