> 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
> Assignee: Christopher Gregorian
> Priority: Major
> Attachments: Emit_size_and_overflow_metrics_from_FairCallQueue.patch
>
>
> 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.
