Conditions that cause events

Conditions that can give rise to instrumentation events include:

• A threshold limit for the number of messages on a queue is reached.

• A channel instance is started or stopped.

• A queue manager becomes active, or is requested to stop.

• An application tries to open a queue specifying a user ID that is not authorized on WebSphere MQ for iSeries, Linux, Windows, and UNIX systems.

• Objects are created, deleted, changed or refreshed.

• An MQSC, or PCF, command that successfully executes.

• A queue manager starts writing to a new log extent.

Note:

Putting a message on the dead-letter queue can cause an event to be generated if the event conditions are met.
