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

             Summary: limit the amount of data returned from jmx/queue control listMessages
                 Key: ARTEMIS-3141
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3141
             Project: ActiveMQ Artemis
          Issue Type: Improvement
          Components: JMX
    Affects Versions: 2.17.0
            Reporter: Gary Tully


The list methods of queue control that are exposed via jmx seem to be unbounded.
  1) they list all messages
  2) they display the full body

To protect both the broker and the browser/UI/client it would make sense to limit both the number of messages and the size of the data that is returned.

Imaging 500k messages pending messages with a body of 10k... and 400k are paged to disk. It would be crazy to try and list those.

I imagine a:
 management-list-messages-max default 256
 management-list-messages-body-max default 256 or some such.

I need to do some more tests to verify the extent a broker will do to support the current api. I note that the browse functionality can be paged and with out a page defaults to 200 messages. That is sensible.
