To tell you the truth, I didn’t know how to start this article about SQL Profiler vs Extended Events. After all, I decided to take mind off things and to watch a movie. The movie was Iron Man 2. In addition to the brilliant performance of Robert Downie Jr., one phrase stuck in my mind and immediately inspired my writing.

“Don’t get so attached to things, learn to let go.”

What is better the old reliable SQL Profiler or something new? My personal choice is Extended Events. Why? To deal with Extended Events, we should go back to SQL Profiler and comprehend its work. First, a new trace is created, and information to be traced is noted.

And thanks to those who take time in sending them to me that it makes a great reminder to what I have missed till date. This blog is from one of such logon failure errors that came from a DBA from one of my consulting engagements. Since the error was simple enough, I thought to respond over mail to solve the problem.
