The Team System Management Model Designer Power Tool is a productivity tool that helps architects and system designers to generate models of an application that contribute to minimized TCO. These models include configuration, instrumentation, health, and performance information. The Team System Management Model Designer Power Tool also assists developers to implement the required instrumentation, and create management packs for monitoring systems such as Microsoft System Center Operations Manager 2007.

Maybe something for the developers but now we are also creating MPs why not go into Visual Studio and start developing apps with the monitoring knowledge we have ;-)

You can download the CTP from Microsoft Download Center.

Now your in the development area anyway you should take a look at the Patterns & Practices - Design for Operations page on Codeplex.
