View DNS query statistics

A website's Overview tab counts the DNS queries Coritan's nameservers answered for its zone over a period you choose. Use it to confirm that resolvers have found your zone after a nameserver change, and to spot names that do not exist or answers that fail.

The domain's DNS must be hosted on Coritan. For a domain whose DNS is elsewhere, the tab shows No query statistics.

1. In the dashboard, go to Websites and select the domain. The Overview tab opens.
2. Choose a Time range: 1 hour, 6 hours, 24 hours, 48 hours, 7 days or 30 days. The tab opens on 24 hours.
3. Read the four counters for that period:
   • Total queries: every query the zone received.
   • NOERROR: queries the zone answered.
   • NXDOMAIN: queries for a name that does not exist in the zone.
   • SERVFAIL: queries the nameserver could not answer.
4. Read the Query analytics chart, which draws the same four counts hour by hour.

The Nameservers card below the chart lists the domain's nameservers when Coritan is its registrar. For a domain registered elsewhere, it says you set the nameservers at the other registrar.

The counters and the chart cover the range you chose, in hourly steps. A zone that no resolver has asked about yet shows No queries in this range.

No queries in this range

No resolver asked for the zone in that period. Check that the registrar lists Coritan's nameservers (Change a domain's nameservers), then choose a longer range.

A high NXDOMAIN count

Clients ask for names the zone does not have. Compare the names your services use with the zone's records on the DNS tab.
