Measures reported by BindQryStatsTest

To be able to understand the workload of BIND DNS, you should track the flow of queries into the server and out of it (to other DNS servers). This is what the BindQryStatsTest test does. This test reports the count of incoming and outgoing queries for each Resource Record (RR) type of the target BIND DNS. Resource Records define data types in the Domain Name System (DNS). Typically, they are stored in binary format internally for use by the BIND DNS. When zone transfers are performed, Resource Records are sent across the network in text format. Some of the common RR types are as follows: A, AAAA, A6, AFSDB, CNAME, DNAME, DNSKEY, SRV, etc.

Using this test, administrators can easily assess the current load on the server and rapidly detect a potential overload condition. Moreover, in times of abnormal load, you can use this test to identify the RR that is seeing maximum traffic and is thus contributing to the load.

Outputs of the test : One set of results for every Resource Record type in BIND DNS.

The measures made by this test are as follows:
