Hi Anuja, In addition to what hasitha has mentioned, I think we should be able to monitor realtime load of the MB as well.
The factors such as 1. How many messages are currently in memory and yet to be written to the database 2. How many messages are sent but waiting for client acknowledgement will be useful. Thanks, Akalanka.
