To verify this setup, right-click on a queue (that has Snooper enabled) and select produce a message. This message should be visible in the Snooper window described above.
The parameter MaximumBufferSize refers to the maximum amount of data that eStudio holds for viewing. If the total data being stored exceeds this value, it clears the existing messages (or clears new incoming messages if the checkbox Discard Incoming Messages if buffer full is checked).

If an application Snoops messages on a destination, it needs to create Subscriber(s) on the System Snooper Topic, which is:

SYSTEM_MESSAGE_SNOOPER_QUEUE

The subscriber gets all messages published on a topic or a queue that has Snooper configured on it.
