Hey Paul -

I use SQL Sentry EM/PA in many environments I support also. No flakiness noticed when I use it normally. Can you be a bit more specific? Maybe someone could help you out more. I find a lot of poorly performing statements with the tool, including those that are executed from within the context of SSIS. Also great for seeing if I have a job schedule conflict/missed job or a job running over/under "normal" execution times.

Let us know a bit more about your needs and what you are seeing and I am sure someone can help out.
