I'm going to be implementing some server-level auditing in SQL Server 2008 R2 Enterprise. Mostly it's just to see successful and failed logins, but I may add a few other items.
This Microsoft whitepaper seems to show that the performance effects of auditing are fairly minimal. As this is now a business requirement, I don't think I have much choice either way anyways, but writing out asynchronously to a file seems to be very efficient and minimally impacting since it uses Extended Events.
Has anyone implemented this in their own environment, and if so, was there any noticeable impact on performance?
Thanks!
