I think so, I've never created the address (nor the queue or the topic) except for the root topic called "gw".<br>
The address is a result of an AMQP 1.0 connection from ditto to enmasse.<br>

Sorry, you're correct. The address is in fact a topic:<br>

<div bgcolor="#FFFFFF"><font size="-1">Hi,<br>
<br>
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.<br>
To be more specific:<br>
Eclipse-ditto is publishing messages to a queue called "gw/tenant/tenant:device". A backend service (python) is subscribed to "gw/#".<br>
In prometheus, I'm getting following artemis_message_counts:</font><br>
<img src="cid:part5.C8680524.E8EF374A@aloxy.io" alt="" class=""><br>
<br>
<div class="gmail-m_3302742300088059084gmail-m_-1845386925811578373gmail-m_8627458255062377794moz-signature">
When I look at the metric "artemis_consumer_count", following records are shown:<br>
<img src="cid:part6.B125E2D6.606848BC@aloxy.io" alt="" class=""><br>
<br>
Any idea on how to prevent the queue from building up?<br>
<br>
Best regards<br>
