JMX is a good tool here. I would also start with some basics. First, determine whether the client is actually connected to the broker box - the "netstat" command is a good one for that. You'll need to know the client's IP address.
Second, if the client connection is confirmed at the network level, check the broker for a broker connection from that client, and see to what the client is subscribed. Third, if subscriptions are found, check their statistics for messages being dispatched to the client. Another approach to diagnosis of this problem - stand up another broker dedicated to diagnosing this one problem and configure the client to connect to the new broker only. That will simplify the things to verify. -- View this message in context: http://activemq.2283324.n4.nabble.com/Problem-with-message-delivery-or-connectivity-tp4703964p4703970.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
