About Passive Monitors

Some elements on a network may not provide a clear up or down status when queried. For example, a message may get logged to the system's Event log by another application (such as an antivirus application alerting when a virus is found). Since these messages/events can occur at any time, a Passive Monitor Listener "listens" for them, and notifies WhatsUp Gold when they occur.

The first step to use this function is to Configure the Passive Monitor Listeners.

After the listeners have been configured, you can Configure Passive Monitors for individual devices.

Passive Monitors Icon

When a passive monitor is configured on a device, the device icon displays a diamond shape on the upper left side.

This shape changes color when an unacknowledged state change occurs on the monitor. After the device has been acknowledged, the icon returns to the above appearance.
