Summary (All Virtual Centers) view

The Summary - All Virtual Centers view displays overall resource utilization information for a group of virtual centers and shows the elements that consume the highest amount of system resources.

This view is made up of the following embedded views:

Virtual Centers view

This view is a tree view. It lists the virtual centers that exist in your environment and shows their state.

Selecting the All Virtual Centers node displays overall resource utilization for all virtual centers in your integrated system, and the elements that consume the highest amount of system resources in the Summary (All Virtual Centers) view on the right. Similarly, selecting a server node shows server-specific metrics in the Virtual Center Summary view on the right.

Virtual Environment Overview

The Virtual Environment Overview provides you with an overview of the selected virtual environment.

The overview has a tile for each type of object in your virtual infrastructure. Each tile shows the number of instances the corresponding object type that exist in your virtual infrastructure, as well as the count of objects of that type in each of the alarm states (Normal, Warning, Critical, Fatal).

You can move the tiles by dragging and dropping until you achieve the desired layout. To hide one or more tiles, on the tool bar on the right, click Edit , and in the popup that appears, click a tile that you want to hide.

Click the object type icon, the object type name, or the object count, to view summary information for that entire object type in the Quick-View. Click an alarm state (for example, warning) on a tile to view summary information in the Quick-View for the objects of that type that are in the selected alarm state.

If an alarm state has a count of zero, then you can not select that alarm state.
