Monitoring Application Progress
The 10 user-configurable events can be used in a variety of ways, including for tracking the progress of an application or procedure. For instance, perhaps you have a complex procedure that is subject to lengthy execution. You can add debugging logic in this procedure to allow for real-time benchmarking via SQL Profiler.
The key to this type of profiling is the use of the sp_trace_generateevent stored procedure, which enables you to launch the User configurable event. The procedure needs to reference one of the User configurable event IDs (82 to 91) that correspond to the User configurable event 0 to 9. If you execute the procedure with eventid= 82, then User configurable event 0 catches these events.
