The DNS Monitor test allows you to measure the availability and response times of a DNS server by performing a lookup.
DNS SERVER: The user can add up to 3 DNS servers during this process, though only one is required.
DOMAIN/IP LOOKUP: Choose the IP address or domain name to lookup.
CHECK DNS: To make sure the DNS server is listening before performing a lookup, check this option.
Set the interval between tests and test timout here. This simply dictates how often to perfrom a DNS lookup and how long to wait for a response.
Round Trip Time tests are used monitor the distance between MCS and the DNS server. If a specific port is required, define it here.
CONSOLIDATE: As it's possible to perform a lookup every few seconds it's usually necessary to consolidate the data for the database. This means an average of all results over a certain time frame are taken and added to the database as one entry.
