DNS Monitoring
DNS Monitoring checks whether the targets behind your DNS records are reachable and shows the result directly in the smoxy interface. Monitoring is opt-in per record: you enable it for individual A, AAAA, or CNAME records in their Advanced Settings.
What is DNS Monitoring?
DNS Monitoring is configured per record. For each A, AAAA, or CNAME record, you can choose a Monitor type under the record's Advanced Settings:
- None (default) - the record is not monitored
- Ping - checks basic reachability of the target
- HTTP - performs an application-level check against the target
Once monitoring is enabled for a record, smoxy shows whether the target responded. This makes it easy to confirm that a record is working - or to catch misconfigurations early.
What does smoxy monitor?
For records with monitoring enabled, smoxy regularly checks whether the target responds. What is checked depends on the selected monitor type:
- Ping verifies basic reachability - for example, whether a server answers at the configured IP address.
- HTTP additionally performs an application-level check against the target.
The status appears next to the record in the DNS overview.
Test Frequency
DNS monitoring runs at a fixed interval of 30 seconds per IP address. The interval is not configurable.
For each check, three queries are sent in parallel from different regions worldwide:
- If at least one region responds successfully, the record is considered online.
- If all three queries fail, the record is marked offline.
Where the Status Is Displayed
Open a domain in smoxy and switch to the DNS Records tab. Records that are monitored show a color-coded status:
- 🟢 Reachable
- 🔴 Not reachable
The displayed state reflects the most recent check.
Notifications
There are no notifications, no history of past checks, and no escalation. DNS Monitoring is a visual aid in the DNS overview, not an alerting system. Pair it with an external uptime monitor if you need notifications.
Caveats
- Results can be skewed by local network restrictions or firewalls between smoxy's checking infrastructure and your target.
- "Not reachable" means smoxy didn't receive a successful response - it does not always mean the service is down.
- With the Ping monitor, only basic reachability is checked; a record may be marked online even if the application running behind the IP is broken. The HTTP monitor additionally checks the target at the application level.
