Hi,

While setting up prometheus to monitor our installation, I noticed the "artemis_message_count" on a specific address is growing while I am subscribed to this address using a wildcard.
To be more specific:
Eclipse-ditto is publishing messages to a queue called "gw/tenant/tenant:device". A backend service (python) is subscribed to "gw/#".
In prometheus, I'm getting following artemis_message_counts:
[cid:part1.0D33C3C4.FD975B6D at aloxy.io]

When I look at the metric "artemis_consumer_count", following records are shown:
[cid:part2.919F7A02.1641CDDF at aloxy.io]

Any idea on how to prevent the queue from building up?

Best regards
