As a developer, I use SQL Profiler quite often. It's a good debugging tool, both to track what my code is doing and to analyse performance problems.
But I've always used it on my development environment, and in a very controlled way.
- Start my application, and get it into a specific state
- Start a trace on the profiler
- Perform a specific sequence of actions on my application
- Stop the trace and examine the results.
Can the SQL Profiler be practically used in an in-production environment?
My first concern is that it would degrade the performance.
My second concern is that, because it's in production, you aren't triggering the interesting actions itself. You would have to leave the profiler running for a long period then analyse the results. Would the result set become too unwieldy? (Taking up too much disk space and being too hard to query).
Does anyone use the SQL Profiler in production?
