-------------------------------------------

             Summary: Expose tasks queue length via JMX
                 Key: CASSANDRA-12758
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12758
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Romain Hardouin
            Priority: Minor
         Attachments: 0001-Add-MBean-to-monitor-max-queued-tasks_2.1.patch, 0001-Add-MBean-to-monitor-max-queued-tasks_trunk.patch

CASSANDRA-11363 introduced {{cassandra.max_queued_native_transport_requests}} to set the NTR queue length.
Currently Cassandra lacks of a JMX Mbean which exposes this value which would allow to:
 
    1. Be sure this value has been set
    2. Plot this value in a monitoring application to make correlations with other graphs when we make changes
