Does WebSitePulse offer DNS monitoring?
Yes, we offer DNS server monitoring. To start monitoring your DNS server create a new target using the DNS advanced target type.
The monitoring agent tries to open an UDP connection to port 53 of the monitored host. If unsuccessful, a connection error is recorded. “NS IN” query is sent to the monitored DNS server. If the server responds with a valid response a successful status is recorded and the connection is closed.
If you just want to test whether the UDP port of your DNS server is opened without sending any request you could also use our "Custom port monitoring" feature.
Here you can read an article about using our services to monitor DNS server.
