Tao has updated his MP. This is a really cool concept of taking some of the most common issues, misconfigurations, and errors that occur with SCOM 2012, and creating a management pack to watch for them.
His most current MP as of this post is http://blog.tyang.org/2014/02/23/opsmgr-2012-self-maintenance-management-pack-update-version-2-3-0-0/
If you want to better understand what his MP is looking for, check out some of the previous posts:
There is a link on his blog to download it and it comes with documentation on how to use it. Very nice community MP that you should consider checking out for your deployments. Also follow his blog if you don’t already, there is TONS of good stuff there.
