B2B Data Exchange contains a mechanism for altering the system administrator and operator when event abnormalities occur.
One of the most useful built-in monitors is the Pending Events Timeout Monitor. This pre-defined monitor alerts system administrators to events that are waiting to be processed for 15 minutes or more. A task that is in the Pending status for 15 minutes or more might have started processing and is taking too long, or its PowerCenter workflow might be down, or another system issue might prevent the task from completing.
The monitor runs every minute.
The pre-defined monitor cannot be deleted, but can be disabled, by setting the execution frequency to Disabled. You can also change the event status time window (by default fifteen minutes).
