Perl script to calculate DNS queries per second in BIND (named)

Tue, 07 Dec 2010 18:53:43 +0000

I’m pricing out DNS providers and was asked what our current queries-per-second currently are. Sadly I had no idea. After lots of Googling I decided there was really no good way to get this information so I decided to parse the logfile myself. First, I turned on logging with timestamp in named.conf:

logging
{
...
 # Query logging 2010-12-07
 channel query-log {
 file "data/queries.log" versions 3 size 10m;
 print-time yes;
 };
 category queries { query-log; };
};
options
{
...
 # Query logging 2010-12-07
 querylog yes;

};
