    ditto - Can this be added to the artemis-configuration used for testing to 
keep as much as possible the two in sync

>             Project: ActiveMQ Artemis
>          Issue Type: New Feature
>            Reporter: Lionel Cons
>            Priority: Major
>
> By default, Artemis deletes inactive addresses and empty queues. This is good 
> to minimize the resources used.
> However, this is problematic for monitoring because counters (like the 
> numbers of received and sent messages) are attached to these objects that get 
> deleted. So a monitoring tool periodically probing the broker may miss these 
> objects that get immediately deleted.
> It would be good to add support for delays. An object would not be 
> immediately deleted but would stay in the broker for a configurable period of 
> time, so that monitoring tools get a chance to get its counters.
> Note that this feature (delayed deletion) already exists in ActiveMQ 5. See 
> the {{gcInactiveDestinations}}, {{schedulePeriodForDestinationPurge}} and 
> {{inactiveTimoutBeforeGC}} parameters in 
> http://activemq.apache.org/delete-inactive-destinations.html.
