Foglight for VMware 7.3.0 - User Guide (Lite version)

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.
