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

             Summary: Restrict/truncate messages attributes to a configurable limit for management views
                 Key: ARTEMIS-3175
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3175
             Project: ActiveMQ Artemis
          Issue Type: Improvement
          Components: JMX
    Affects Versions: 2.17.0
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 2.18.0


We still populate lots of per message data. ARTEMIS-3141 limits the number of messages that are returned by default however the message data is still displayed in full.
With a few kbytes of data in message properties, it can quickly get become a burden.
The open type message body is called BodyPreview - but we put the whole body in there at the moment.

This enhancement will add an address setting - *_managementMessageAttributeSizeLimit_*
with a reasonable 256 default. 
That will truncate all message attributes returned in JSON or JMX OpenData to this value.
Most properties will fit in that limit and be fully visible, anything bigger will be difficult to view and is too much data to be exposing in bulk to a console or client.
