What are Extended Events?

I have seen extended events listed along with DDL triggers, trace, and other SQL Server features. What are they and should I be using them?

MSDN provides an excellent overview at http://msdn.microsoft.com/en-us/library/bb630354.aspx .

In a situation where no other explanation for slowdowns can be found or when using SQL Server on a server that also has other duties they can be very useful for troubleshooting slowdowns. Generally when using SQL Server on a dedicated machine they are more likely to clutter the display than provide useful information.

If you'd like to learn all about Extended Events I suggest reading Jonathan Kehayias' whitepaper on the matter:

http://msdn.microsoft.com/en-us/library/dd822788.aspx

Jonathan has also developed an application to help you use and view the extended events information called Extended Events Manager. The application is free and available at Codeplex: http://extendedeventmanager.codeplex.com/

New code box

There's a new way to format code on the site - the red speech bubble logo will automatically format T-SQL for you. The original code box is still there for XML, etc. More details here.
