How to add a DNS monitor?...
Dynu's System Monitoring & DNS Failover service helps you monitor critical services
from multiple geographic locations and automatically respond when downtime is detected.
You can log into the control panel to add and manage your monitors.
A DNS monitor checks whether a specified name server is correctly resolving a given hostname. It sends DNS queries at regular intervals using either TCP or UDP, allowing you to verify that your authoritative or recursive name servers are responding as expected. If the name server fails to respond from two or more geographic monitoring locations, you will be notified and any configured failover actions will be triggered.
To add a DNS monitor in the control panel, you may follow these 3 steps.
Step 2
Configure your DNS monitor using the following fields.
Monitor Type Choose "DNS".
Friendly Name A descriptive label for the host and service being monitored. This name will appear in any notification emails sent to you. For example, dynu.net domain resolution .
Protocol Choose either "TCP" or "UDP", depending on which DNS transport protocol you want to test. UDP is the standard protocol used for most DNS queries, while TCP is typically used for larger responses such as zone transfers or DNSSEC.
Name Server The DNS server to query. This can be an authoritative name server for your domain or any other resolver you wish to test. For example, ns1.dynu.com .
Hostname The hostname to look up against the specified name server. For example, dynu.net.
Monitoring Interval How often the DNS check is performed. You may choose any value between 1 minute and 1 day using the slider. For example, 2 minutes .
Locations Choose 4 geographic monitoring locations from the available list (e.g., New York, Dallas, Seattle, Toronto, London, Paris, Stockholm, Tokyo, Singapore, Sydney, Sao Paulo, Mumbai). Your service is checked simultaneously from all selected locations, and downtime must be confirmed from two or more locations before an alert is triggered — eliminating false alarms from single-point network issues.
Step 3
Click Continue to save the monitor. You can then proceed to set up notification contacts and failover actions. To verify a DNS lookup result independently, you may also use our DNS Lookup tool.
