> For rpc metrics the port number determines what rpc calls are being tracked.
> _Example_: Namenode can have different rpc ports for Datanode and clients and
> healthchecks. Presently since the port number is not a part of the
> metricsName the two metric entries will step on each other in AMS store.
> This patch only addresses the fix for HDFS.
