             Summary: Add Region Server ID to metrics
                 Key: HBASE-7059
                 URL: https://issues.apache.org/jira/browse/HBASE-7059
             Project: HBase
          Issue Type: Improvement
          Components: metrics, regionserver
    Affects Versions: 0.92.1
            Reporter: James Kinley


When running multiple Region Servers on a single node monitoring tools are 
unable to distinguish between the metrics, because they group them by hostname. 
E.g. Ganglia shows accumulated metrics for "hbase.regionserver.blockCacheCount" 
for all Region Servers running on the same node. 

If a Region Server ID was added to the metric, e.g. 
"hbase.regionserver001.blockCacheCount", then Ganglia will be able to display 
the metrics for each Region Server separately.
