[rabbitmq-discuss] rabbitmq Mnesia database

Thu Apr 3 21:16:45 BST 2008

Hi, Mathias,
Yes, we want to inspect the messages currently held by the queue
"queuename". I sent to the mailist before to suggest it will be good to
see how many messages has been gone through the queue, how many are
still being held...

If you can advise how to use running erlang to inspect the queue with
its message, that will be great. Thank you.

Best,
Ying

AMQP messages do not pass through mnesia. Mnesia only stores routing and

administrative data.

What are you trying to accomplish? Do you want to inspect the messages 
currently held by the queue "queuename"? There isn't really a convenient

way of doing that. You would have to inspect the state of the running 
Erlang process for that queue.
