Subject [jira] [Created] (HBASE-12328) Need to separate JvmMetrics for Master and RegionServer

Sanghyun Yun created HBASE-12328:
------------------------------------

             Summary: Need to separate JvmMetrics for Master and RegionServer
                 Key: HBASE-12328
                 URL: https://issues.apache.org/jira/browse/HBASE-12328
             Project: HBase
          Issue Type: Improvement
            Reporter: Sanghyun Yun
            Priority: Minor


tag.ProcessName of JvmMetrics is "IPC".
It is same both Master and RegionServer.

{code:title=HBase(Master and RegionServer)'s Metrics Dump}
...
"name": "Hadoop:service=HBase,name=JvmMetrics",
"modelerType": "JvmMetrics",
"tag.Context": "jvm",
"tag.ProcessName": "IPC",
"tag.SessionId": "",
...
{code}

When I use HBase with Ganglia,
I wrote tagsForPrefix.jvm=ProcessName in hadoop-metrics2-hbase.properties.
{code:title=hadoop-metrics2-hbase.properties}
...
*.sink.ganglia.class=org.apache.hadoop.metrics2.sink.ganglia.GangliaSink31
hbase.sink.ganglia.tagsForPrefix.jvm=ProcessName
...
{code}

But, Ganglia generate only one RRD file because tag.ProcessName is "IPC" both Master and Regionserver.

I think it need to separate JvmMetrics for Master and RegionServer.
