> Add support for delays before deleting addresses and queues
> -----------------------------------------------------------
>
> Key: ARTEMIS-1856
> URL: https://issues.apache.org/jira/browse/ARTEMIS-1856
> 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.
