Subject [jira] [Resolved] (ACCUMULO-1817) Use Hadoop Metrics2
Date Fri, 05 Dec 2014 23:19:13 GMT


Josh Elser resolved ACCUMULO-1817.
    Resolution: Fixed

We now support both the existing (henceforth referred to as "legacy") JMX endpoints as well
as Metrics2-handled endpoints (by default).

Verified that JMX entries are still being populated for both variants (current and legacy)
and also verified Graphite sink for current metrics (did not verify ganglia).

> 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.
