We are using a Tibco EMS Queue to send messages. We are the publisher. Whenever we are publishing messages it seems someone is consuming that. When we asked the other team who is subscribing, they said they are not consuming.
Is it possible to know to who is connected to the EMS Queue and consuming the messages?
If you've got access to the EMS dashboard utility then bring up the view of all queues on the server, then right-click on the queue you're interested in and select "Consumers" and it will give you a detailed view of who is attached to a queue.
If you don't have the dashboard app then you'll probably need to hassle your EMS admins for a copy. It's part of the standard install, so they will have it.
