Unterstützte Agenten	Active

This is an active check that sends a DNS query to a DNS nameserver.

You can give the DNS name to query for. This can serve different purposes. For one, you can monitor whether a DNS server is operational. Another purpose is to check whether specific DNS queries are resolved in an expected manner. The DNS nameserver needs to be specified accordingly.

It can compare the IP it gets back against a given IP and return CRIT if they do not match. It can check the DNS server to be authoritativ for the lookup. It can check response times against given thresholds for WARN and CRIT.

This check can be configured by Wato.
