The stability of ActiveMQ could be improved. Occasionally, the MQTT broker goes down, requiring a restart, so enhancing its stability would be beneficial. Also, the current monitoring tools could be more user-friendly and faster. I'm currently using the default ActiveMQ monitoring tool, which is quite basic. It would be great if it could provide more detailed insights into the queues, topics, broker status, publisher status, and consumer status. For additional functionality, I suggest making it easier to install and monitor the queues, topics, broker status, publisher status, and consumer status. Improved monitoring tools would help avoid needing to manually access the server for monitoring purposes.
