The broker configuration property logDeadMsgs controls the logging of events related to the dead message queue. When dead message logging is enabled, the broker will log the following events:
A message is moved to the dead message queue.
A message is discarded from the dead message queue (or from any physical destination that does not use the dead message queue).
A physical destination reaches its limits.
Dead message logging is disabled by default. The following command enables it:
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.
