It took a while, but I finally tracked down the information I needed. SCOM has an SDK. In the SDK is a nice little page showing how to test & debug scripts. One of the links on that page leads out here to a great article on the VBScript debugger. That’s what I needed (along with the DLL’s to register). Anyway, I’ve almost got my first monitoring script up & running. I’ll post it on here once I do.
We also have a great article on debugging runtime scripts for Opsmgr at http://www.systemcenterforum.org/scripting-series-part-3-debugging-runtime-scripts-for-opsmgr-and-sce/
You’re right. That’s a great article too.
