Description

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

HBase(Master and RegionServer)'s Metrics Dump

...
"name": "Hadoop:service=HBase,name=JvmMetrics",
"modelerType": "JvmMetrics",
"tag.Context": "jvm",
"tag.ProcessName": "IPC",
"tag.SessionId": "",
...

When I use HBase with Ganglia,
I wrote tagsForPrefix.jvm=ProcessName in hadoop-metrics2-hbase.properties.

hadoop-metrics2-hbase.properties

...
*.sink.ganglia.class=org.apache.hadoop.metrics2.sink.ganglia.GangliaSink31
hbase.sink.ganglia.tagsForPrefix.jvm=ProcessName
...

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.
