Replying to myself for the benefit of others: I can't make it to work over the net, at least between windows and linux machines, but the following works perfectly fine if run directly on the server. [root@fakehost bin]# ./twiddle.sh -u admin -p XXXXX get "jboss.mq.destination:service=Queue,name=QUEUE-XXX" QueueDepth | QueueDepth=0 | [root@fakehost bin]# ./twiddle.sh -u admin -p XXXXX get "jboss.mq.destination:service=Queue,name=QUEUE-YYY" QueueDepth | QueueDepth=0 | [root@fakehost bin]# ./twiddle.sh -u admin -p XXXXX get "jboss.mq.destination:service=Queue,name=QUEUE-YYY" SubscribersCount | SubscribersCount=10 | [root@fakehost bin]# ./twiddle.sh -u admin -p XXXXX get "jboss.mq.destination:service=Queue,name=QUEUE-XXX" SubscribersCount | SubscribersCount=10 The attribute SubscribersCount tells you how many subscribers are listening on the queue, while QueueDepth tells you how many messages are currently in the queue.
