Christopher Gregorian commented on HADOOP-15481:
------------------------------------------------
Updated! I think that covers everything, as well as the style suggestions and
docs changes.
Example line output:
{{1547173433343 rpc.FairCallQueue: Context=rpc, namespace=ipc.8020,
Hostname=hostname, FairCallQueueSize_0=0, FairCallQueueOverflowedCalls_0=0,
FairCallQueueSize_1=0, FairCallQueueOverflowedCalls_1=0, FairCallQueueSize_2=0,
FairCallQueueOverflowedCalls_2=0, FairCallQueueSize_3=0,
FairCallQueueOverflowedCalls_3=0}}
Thanks for the review!

> 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.
