-------------------------------------------
Summary: Add Pending Message Size Metrics
Key: AMQ-5923
URL: https://issues.apache.org/jira/browse/AMQ-5923
Project: ActiveMQ
Issue Type: New Feature
Components: Broker
Reporter: Christopher L. Shannon
Assignee: Christopher L. Shannon
Fix For: 5.13.0
Right now the PendingMessageCursor keeps track of the number of pending
messages (the size() method). It would be useful to also report back the total
message size besides just the count so we know how much memory or disk space is
being used by pending messages.
Now that KahaDB is keeping track of the size of each message as of 5.12, it
should be possible to report back this value in a non-blocking way. For a
Queue this is pretty straightforward but for DurableSubscriptions some work
will need to be done to keep track of the message size for unacked messages for
each subscription.
