Trace-scrubbing Tools

Andrew Zanevsky shares his trace-scrubbing procedures that make it easy for you to handle large trace files and aggregate transactions by type–even when captured T-SQL code has variations.

SQL Server Profiler is a veritable treasure trove when it comes to helping DBAs optimize their T-SQL code. But, the surfeit of riches (I'm reminded of the Arabian Nights tale of Aladdin) can be overwhelming. I recently had one of those "sinking" feelings when I first tried to make sense of the enormous amount of data collected by traces on a client's servers. At this particular client, the online transactions processing system executes more than 4 million database transactions per hour. That means that even a 30-minute trace that captures "SQL Batch Completed" events results in a table with 2 million rows. Of course, it's simply impractical to process so many records without some automation, and even selecting the longest or most expensive transactions doesn't necessarily help in identifying bottlenecks. After all, short transactions can be the culprits of poor performance when executed thousands of times per minute.
