How to monitor a DNS server using ActiveXperts Network Monitor
ActiveXperts Network Monitor is a software solution you need to scan your network servers, workstations and devices for failures or irregularities. With ActiveXperts Network Monitor, you can identify issues and fix unexpected problems before your others even know they've happened. ActiveXperts Network Monitor maximizes network availability by monitoring all aspects of your servers, workstations, switches, routers, printers and any other devices. It can also detect temperature, humidity and other environmental aspects in your server rooms.
The Domain Name System is a hierarchical distributed database and an associated set of protocols that define
a mechanism for querying and updating the database, a mechanism for replicating the information in the database
among servers and a schema of the database.
Use ActiveXperts Network Monitor to check the availability of a DNS server by resolving a DNS record (e.g., A
record, CNAME record, MX record, etc.)
and compare the result against a preconfigured value.
A DNS Server check requires the following parameters:
DNS Server - the IP address or hostname of the DNS server that you want to check;
Name - The DNS name that needs be resolved. The result of this resolve is matched against the expected;
Type - The DNS record type of the DNS record. Valid record type are: 'A Record', 'MX Record' 'CNAME Record' or 'Any Record';
IP address(es) - The expected IP number(s). If the query result does not include the given IP address, the check will fail. Otherwise, the check will succeed. Please note that a DNS query can return more than one IP address. In case the 'Type' was set to 'CNAME Record', the expected result is a host name, not an IP number.
