DNS

The Domain Name Server (DNS) monitor is a simple service monitor that checks for the DNS on port 53. If a DNS service does not respond on this port, the service is considered Down.

Provide a unique name and description for the monitor, then configure the following:

• Timeout. Enter the length of time WhatsUp Gold attempts to connect to the selected device. When the specified time is exceeded without connecting, a timeout occurs and WhatsUp Gold stops trying to connect to the server. This is considered a failed connection.
• Use in rescan. Enable this option to have the monitor appear in Device Properties. If enabled, clicking Refresh Connectivity within the Device Properties interface adds the monitor to the selected device if the applicable protocol or service is active on that device.
