Event message reference

Use this page to obtain an overview of information about the format of event messages.

For each instrumentation event, information is returned in both the message descriptor and message data parts of the events messages.

Event message format
Event messages are standard IBM MQ messages containing a message descriptor and message data.
Event message MQMD (message descriptor)
The message descriptor for an event message contains information that a system monitoring application can use, such as the message type and format, and the date and time that the message was put on the event queue.
Event message MQCFH (PCF header)
The message data in event messages is in programmable command format (PCF), as used in PCF command inquiries and responses. The message data consists of two parts: the event header and the event data.
Event message descriptions
The event message data contains information specific to the event that was generated. This data includes the name of the queue manager and, where appropriate, the name of the queue.
