Adding and editing a Domain Service (DNS) Monitor

The DNS monitor is a simple service monitor that checks for the DNS (Domain Name Server) on port 53. If no DNS service responds on this port, the service is considered down.

To add or edit a DNS active monitor:

1. Click the Admin tab, then click Monitor Library. The Monitor Library dialog appears.
2. Click the Active tab. The Active Monitor list appears.
3. Click New and select DNS Monitor from the list to create a new DNS monitor. Click OK.
   - or -
   Select the DNS monitor you want to change from the list of current monitors, and then click Edit.
4. Type or select the appropriate information in the following fields.
   • Name. Type a name for the active monitor. This name displays in the Active Monitor Library.
   • Description. Type a short description for the monitor. This description displays next to the monitor in the Active Monitor Library.
   • Timeout. Type a timeout value. This is the length of time in which the service is given a chance to respond. If there is no response in this amount of time, the service is considered down.
   • Use in Rescan. Select this option to have the monitor appear in the Active Monitor list on the Device Properties dialog. WhatsUp Gold adds the monitor type to the device during a rescan, which is launched using the Rescan button on the Device Properties dialog, if the protocol or service is active on the device.
5. Click OK to save changes.

After configuring an active monitor in the Active Monitor Library, add the monitor to devices.
