Say you have an sql trace for the event ‘TSQL SQL:StmtCompleted’ you are, most probably, NOT interested in the sql statements executed through the SQL Server Agent for instance. Filters below remove most of the unwanted ‘internal’ tsql.

The contents of your tracefile will become more meanigfull and not unimportant small …
