Active monitors poll target devices for important information such as ping accessibility, device services, device files and folders, and more. Active monitors regularly query or poll the device services for which they are configured and wait for responses. If a query is returned with an expected response, the queried service is considered "up." If a response is not received, or if the response is not expected, the queried service is considered "down" and a state change is issued on the device.
In an effort to help you manage your network after you install the application, WhatsUp Gold includes various pre-configured active monitors. These pre-configured monitors display in the Active Monitor Library. As you configure new active monitor types, they are added to the library.
The Active Monitor Library displays active monitors configured and available to apply to network devices. For more information, see Configuring Active Monitors.
In addition to configuring relevant monitors, you must assign monitors to the devices you want to monitor. For more information, see Assigning active monitors.
