The issue here is that the logging in BIND does not contain the
responses sent, only the questions asked (and there is no logging that
tells if an answer was provided!)

There are a number of ways you can extract this information, but all of
them require external applications.

Judicious use of "tcpdump" or "wireshark" will provide what you want.

If you want pretty graphs, I've enjoyed DSC over the years
(http://dns.measurement-factory.com/tools/dsc/) and can't wait for the
"next generation" of it to show up.
