Figure 78. Summary tab

Each tile shows the number of instances of the corresponding object type, as well as the counts of objects of that type in each of the alarm states (Normal, Warning, Critical, Fatal).

More detailed information for the selected object or objects is displayed in the collapsible views below the Summary view.

On a tile, click the object type icon, the object type name, or the object count, to view a popup that lists all objects of the corresponding type, along with their respective states. Click a column header on the popup to change the sort order. Click an object in the popup list to view details for that object in the VMware Explorer dashboard.

On a tile, click an alarm state icon or the number below it to view a popup that shows the outstanding alarms of that state for the corresponding object type.

If an alarm state has a count of zero, then you can not select that alarm state. When you click a normal state icon or count, the VMware Explorer page is refreshed, but you do not see an alarm popup because there are no alarms associated with the normal state.

In the Virtual Infrastructure view, select a Virtual Center, datacenter, cluster, ESX host, resource pool, or a virtual machine.
