Dead message logging is disabled by default. Enabling dead message logging allows the broker to log the following events:
The broker moves a message to the dead message queue
The broker discards a message from the dead message queue and from any physical destination that does not use the dead message queue
A physical destination reaches its limits
The following command enables dead message logging:
imqcmd update bkr -o imq.destination.logDeadMsgs=true
Dead message logging applies to all physical destinations that use the dead message queue. You cannot enable or disable logging for an individual physical destination.
