Calculating queries per second (BIND 8)

[Chris Pile]

Below is an example for BIND 8:

for i in 1 2 3;do > /var/log/querylog;ndc querylog;sleep 1;ndc querylog;wc /var/log/querylog;sleep 5;done

named.conf:
logging {
    channel my_querylog {
        file "/var/log/querylog" versions 4 size 512K;
        severity info;
        print-category yes;
        print-severity yes;
        print-time yes;
    };
    category queries {
        my_querylog;
    };
};

If you edit your named.conf file, do a "ndc reload" after to reload the config.
