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?
Use Hadoop Metrics2
-------------------
Key: ACCUMULO-1817
URL: https://issues.apache.org/jira/browse/ACCUMULO-1817
Project: Accumulo
Issue Type: New Feature
Reporter: Corey J. Nolet
Assignee: Billie Rinaldi
Labels: proposed
Fix For: 1.7.0
Time Spent: 0.5h
Remaining Estimate: 0h
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.
