Screenshot 43 - DNS server check parameters dialog
The DNS server check requires the following parameters:
• Type of record – Specify the record type which needs to be
defined by the DNS server. This can be an A record or any other
record type present in the drop down list.
• Host/Domain Name to query – Specify the hostname or domain
that you wish to resolve (E.g., www.google.com).
• Record values – Specify the expected return value(s). This is the
value/string which will be compared to the value returned by the
DNS Server ( i.e., the return value).
E.g., If an A record type was selected, the check will query the
DNS server to resolve the IP address of the host/domain specified
in the ‘Host/Domain to query’ field. This query should return one or
more IP addresses which will be compared to the IP(s) specified in
the ‘Record Values’ field.
NOTE: Since a DNS query can return more than one IP address,
this check allows you to specify multiple return values separated
by a comma (,) e.g., 209.217.53.213,66.172.16.32.
• Interpretation of values – Specify how this check will interpret the
result after comparing the returned value to the parameter
specified in the ‘Record values’ field.
E.g., If you select “Find all of the specified values, fail if other
values are found”, the check will fail only if the returned value does
not entirely match to the value specified in the ‘Record values’
field.
