@cshannon although looking at the PR now you added persistent size into
page counters... but as I read it, it is not persistent...
We should go all the way in.. i.e... persist the new size metric along with
the page counters... or all the way back.. i.e... only give user's paging
metrics through page size...
Implementing the counter on the journal is no big deal.. but I would like
to keep it compatible... older versions of the journal should still be
compatible.

> Key: ARTEMIS-1663
> URL: https://issues.apache.org/jira/browse/ARTEMIS-1663
> Project: ActiveMQ Artemis
> Issue Type: New Feature
> Components: Broker
> Affects Versions: 2.4.0
> Reporter: Christopher L. Shannon
> Assignee: Christopher L. Shannon
> Priority: Major
>
> The purpose of this Jira is to enhance the message count metrics and to add
> size metrics for Queues. By size metrics I mean the encoded size of all the
> messages (for large messages this will include body as well). Right now we
> track memory usage but it is also very useful to know exactly how much data
> is pending on a Queue to be consumed.
> The scope of this will be support for tracking the count/size of pending
> messages, count/size of delivering messages, and count/size of scheduled
> messages. For each of these categories durable size metrics will be tracked
> as well. The paging store will also support tracking of size metrics as well.
> These new metrics will be exposed through JMX to allow users to view the
> statistics. Also by tracking these new values it will allow for enhanced
> features in the future (ie new flow control options)
