>             Project: ActiveMQ Artemis
>          Issue Type: Improvement
>          Components: JMX
>    Affects Versions: 2.17.0
>            Reporter: Gary Tully
>            Assignee: Gary Tully
>            Priority: Major

>          Time Spent: 0.5h
>  Remaining Estimate: 0h

> 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.
