    [ https://issues.jboss.org/browse/AS7-5448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714665#comment-12714665 ] 

Mathieu Lachance commented on AS7-5448:
---------------------------------------

in java.util.concurrent.ThreadPoolExecutor there's a getter on the workQueue which return a java.util.concurrent.BlockingQueue.
According to javadoc :
    /**
     * Returns the task queue used by this executor. Access to the
     * task queue is intended primarily for debugging and monitoring.
     * This queue may be in active use.  Retrieving the task queue
     * does not prevent queued tasks from executing.
     *
     * @return the task queue
     */

I'd like the BlockingQueue::size() be exposed through jmx. that way, it will be possible to know if there's queued element waiting to be run.

> thread pool exposed in jmx is still missing the queue size which is an essential metric to evaluate the system load.
