scom missing performance counters

I recently had to make some changes to my scom test environment server. It’s a single virtual machine with scom, sql, ssrs, the works on it. Despite what one would think, it has performed well with about 30 agents. Recently I added about that many more and it pushed up the ram to the 4gb max that I had given it. When I added more I realized I had used 2008 x32 for the OS (oops) and was not able to see the extra ram. After some research I found that I could do an upgrade from 2008 standard to enterprise, which is what I did. Afterwards, scom wouldn’t run because the SDK service would not start. This is the event log message.

After some research I found this article from Microsoft that contains instructions on how to fix this problem.

SCOM Windows 2008 R2 Printer MP

Ran across this custom MP by Kevin Holman. Nice! Thank you!

cleaning up the default management pack

SCOM has what I feel is a major bug in that it will allow you to save items (monitors, rules, overrides, etc.) in the default MP. Doing this is bad for a lot of reasons, and not only does SCOM allow you to do this, but it is the default option as well. In my case it turned out that an occasional lack of attention allowed me to do this and then removing MP’s later becomes a huge pain in the rear. Anyway I found this good article on how to clean up the mess.
