How to query for queues that have a specific word in it

Question

What I was doing is:

rabbitmq_queue_messages_published{queue="Specific.Queue.String.With.TheWord.Apple"} 

to get the number of messages published in the Specific.Queue.String.With.TheWord.Apple queue.

But I have like... 50 queues that I want to look at, whose commonality is that they have this word in the queue name.

How do I query for the number of messages published in queues with this specific word?

Answer 1

Use regex label filter:

rabbitmq_queue_messages_published{queue=~".*TheWord.*"}

Note that .* must be added at both sides of TheWord, since Prometheus automatically adds anchors to the regexp. I.e. it converts regexp to ^(?:regexp)$
