It took me a while to find all the little pieces to put together a custom rule that used data collected through TSQL. In fact, because it took so much work to pull all the little pieces together, I wrote an article describing how I did it. This isn’t a wonderful new invention. It’s just the publication of a bunch of research. If you’re an Operations Manager expert, this isn’t for you. If you’re like I am, trying to find your way through the forest, this little bit of map will hopefully provide some assistance. Available at SQL Server Central.
