DB2 Version 10.1 for Linux, UNIX, and WindowsEvent monitors
Monitoring
table functions and snapshot routines return the values of monitor
elements at the specific point in time the routine is run, which is
useful when you want to check the current state of your system. However,
you might not always want to monitor points in time. There
are many times when you need to capture information about the state
of your system at exactly the time that a specific event occurs. Event
monitors serve this purpose.
Event monitors can be created to capture point-in-time information related to different kinds of events that take place in your system. For example, you can create an event monitor to capture information when a specific threshold that you define is exceeded. The information captured includes such things as the ID of the application that was running when the threshold was exceeded. Or, you might create an event monitor to determine what statement was running when a lock event occurred.
