Carrying on my series of posts on SQL Server and Disk IO it’s time to cover the old stalwart that is perfmon (referred to in Windows as Performance Monitor) which I know anyone who has delved into any Windows performance issue will have some familiarity with, so I’m not going to cover what it is or how to use it. The principal reason for this post is to add my own experiences of using perfmon to turn it into a sql performance monitor to track down issues and monitor SQL Server performance.
