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.

Current Active Alarms Monitor
The Current Active Alarms monitor shows any active alarm that has not yet been cleared. It is one of the four standard monitors available in Alarm mode. Current Active Alarms is a table that has four fields and appear by default. However, nine fields are available for selection. See Table 1 for a description of the table.
Table 1: Current Active Alarms Monitor
Table Column | Description | Shown in Summary by Default | Shown in Detailed View by Default |

Severity | The severity of the alarm. Severity levels are:
| Yes | Yes |
Entity ID | The identification of the entity responsible for causing this alarm. The Entity ID is the key for correlation of events into an alarm. The Entity ID could be a MAC address of a radio or an IP address of the device. | Yes | Yes |
Source | The IP address of the device or network element that generated the alarm. The SNMP agent is located at the source IP. In most cases, the source IP is the IP address of the switch or controller. | No | No |
Reporting Device | The hostname or IP address of the reporting device. | Yes | Yes |
Creation Date | The date and time the alarm was first reported. | No | No |
