What instrumentation events are

In WebSphere MQ, an instrumentation event is a logical combination of conditions that is detected by a queue manager or channel instance. Such an event causes the queue manager or channel instance to put a special message, called an event message, on an event queue.

WebSphere MQ instrumentation events provide information about errors, warnings, and other significant occurrences in a queue manager. You can use these events to monitor the operation of queue managers (in conjunction with other methods such as NetView(R)). This chapter tells you what these events are, and how you use them.

Figure 1 illustrates the concept of instrumentation events.
