Christopher L. Shannon commented on ARTEMIS-1663:
-------------------------------------------------

[~clebertsuconic] - good catch, I had increased that encodeSize because I 
initially was storing a size value there in an early version of this patch but 
then took it out and apparently forgot to revert back the encodeSize to the 
original 

> Add enhanced message count and size metrics for Queues

> 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)
>
