It is really not a good idea to turn on advanced debug logging except to
diagnose a problem. DNS can be asked to resolve hundreds of queries a minute
or more, logging these actions for an extended period put considerable load
on a DNS server which normally requires very little CPU usage and can cause
DNS to overload and fail.
For a short period you can turn on debug logging to see what queries are
sent to DNS
 
But I still need to know how I can understand DNS log file. Any web
site? I cannot find one.
