Use Cases for Creating a Global View Extension
Global view extensions can be used to create dashboard-style data views or console-style applications.
Dashboards
You can use a global view extension to create a dashboard-style data view. A dashboard aggregates data from different sources in the vSphere environment together in one unified data view. For example, you can create a dashboard that provides status information about all custom company-branded objects in the vSphere environment.
Consoles
You can use a global view extension to create a console-style application that is displayed in the vSphere Web Client main content area. The vSphere Web Client Tasks Console and Events Console are examples of this kind of global view.
