cleaning up the default management pack

December 10, 2010

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.

SCOM: powershell run space failed to start

December 7, 2010

I have been getting these messages since day 1 and tried various things that didn’t work to resolve.

Below I am pasting an example rule with full text so that if someone is searching they will find it. This is one specific alert, I was having an issue with all non microsoft powershell scripted discoveries. For me this was 99% from the XSNMP SCOM Management Pack. To be clear the MP was not the cause of the problem, only the one that tried to run PS (and not work) the most.

Eventually the scripts would time out like this:

The issue turned out to be  a permissions issue with the health service since it was trying to run these powershell scripts as local system. This article is the one that finally jogged my memory appropriately. Thank you to the author!
