Using Monitor Mode for Virtual Devices

The Monitor mode for virtual devices in your network enables you to view details about your virtual network using the following tabs:

  • Summary—Displays the status of the virtual network, virtual machine, or virtual switch, active alarms, and the number of hosts and the version of VMware ESXi that is running on each host.

  • vMotion History—vSphere vMotion is a feature that enables live migration of running virtual machines from one host to another with zero downtime and continuous network availability. You can view the status of the history of all the vMotions for your virtual network in the vMotion History tab. For more details, see Viewing vMotion History in Network Director.

Your current scope—that is, your view and node selection in the View pane—affects which Monitor widgets are available. For example, if you select a virtual switch, Network Director displays the status and the active alarms for the selected virtual switch.
