Hi Chintana,

1. Users will be able to enable message activity tracing as same as we
enable logging for a class. There is a class called "MessageTracer". Users
can enable log levels for that class and trace message activities.

2. No. Users can't enable tracing for a particular queue or topic.

3. No. This is not specific to any protocol.

Thanks,
Anuja.
