A few years ago, I wrote a powershell script that returns the entire base and host class path for a given class, including all available properties on each of the classes. This can be useful in a few different scenarios, including management pack development.

I haven’t used the script in a while, but the other day ran into a situation where it was quite handy. I had to update it to work with SCOM 2012, however, so I thought I would post the updated script here for future reference.

You can find the SCOM 2007 version here.

##This script accepts a class name, and returns the entire
##Base class path.  It also returns Host Class for each
##Base class returned.  You'll see the entire
##class path for the given class.
