[jira] [Created] (HADOOP-15481) Emit FairCallQueue stats as metrics

Erik Krogen created HADOOP-15481:
------------------------------------

             Summary: Emit FairCallQueue stats as metrics
                 Key: HADOOP-15481
                 URL: https://issues.apache.org/jira/browse/HADOOP-15481
             Project: Hadoop Common
          Issue Type: Improvement
          Components: metrics, rpc-server
            Reporter: Erik Krogen


Currently FairCallQueue has some statistics which are exported via JMX: the size of each queue, and the number of overflowed calls per queue. These are useful statistics to track over time to determine, for example, if queues need to be resized. We should emit them via the standard metrics system.
