When using ActiveMQ, some problems troubles me:
1. When broker crashed or stopped, messages from sender will be lost(I set timeout, because the sender have others to do).
2. Consumer receives all messages from broker, but how i know the consumer received all messages(zero lost).
3. If message is lost, i want to know it immediately.
In production, I want to monitor the activemq, and know which message is lost. Can anyone give me a favor?
