In Operations Manager, views are groups of managed objects that have a commonality, which is defined in the view properties. When you select a view, a query is executed and the results of the query are displayed in the results pane.
Several views are created by default when Operations Manager is installed. Management packs also contain views. When a management pack is imported, a folder is created in the Monitoring pane. This folder contains the views that are defined in the management pack. You cannot change these views, and you cannot add new views to the Management Pack folder. However, you can create a folder in the Monitoring pane and create views that appear in your folder.
There are several view types, each displaying a different aspect of monitoring data. The following example demonstrates how to create a state view and a diagram view. A state view displays relationships between components, computers, and computer groups. A diagram view displays a graphical view of a set of managed objects and how they relate to one another.
