We will close this section with an example of the functionality and presentation of PowerShell compared to the OpsMgr console. We created a custom user role in the Security -> User Roles node of the OpsMgr Administration pane, named Partner Staff Acme. In Figure 3.18, you can see the properties of that user role, in a window launched from the console.

To access the Properties window in Figure 3.18, you simply right-click the user role in the OpsMgr console and select Properties. Notice that there is one user, RLorenzo, who is a member of that role in the ODYSSEY domain. Now we will use PowerShell to access the same information.

In Figure 3.19, notice the command window with the output of the PowerShell cmdlet get-UserRole. You can see the same information, such as the description of the role and the membership for RLorenzo. However, to achieve that output, you have to know the GUID (Globally Unique Identifier), a code name that is a long set of alphanumeric characters associated with the Partner Staff Acme user role. To learn the GUID of that role, you first have to use PowerShell to list the GUIDs for all the created and installed user roles. Of course, you also have to learn the syntax of the cmdlet. So there is a learning curve, and a rather brutal interface involved. For the true scripter, however, PowerShell could become the presentation layer of choice in some situations, and it adds the ability to perform OpsMgr actions in batch mode.

Summary

This chapter promised a look inside OpsMgr from the macro and micro perspectives. We described first how OpsMgr components are deployed on a single server to a small organization, or across many servers for the large enterprise. We also closely examined the communication channels used between components. We next covered how management packs encapsulate and distribute knowledge about objects and classes of objects, including relationships between objects. Then we looked even deeper at the workflows occurring between modules in a management pack. Finally, we discussed how the Operations console, Web console, and PowerShell present useful management information to the operator and administrator.

With this information, you are ready for the next two chapters, where we discuss designing an OpsMgr 2007 implementation.
