Hi,
I've written some middleware that takes the stats channel from bind and
translates it to cacti/cricket/mrtg
<http://members.iinet.net/~pyard...@ihug.com.au/projects/?project=bind9_5_counters>.
If you haven't looked at what the XML stats channel can give you should
take a look at it in the Bind doco.
Another tack could be log analysis.
Nomium offer some free dns performance testing tools

Hi everyone - I'm at Google and currently starting on a mini-project to
get some more insight into how our BIND servers are performing. Our
first thoughts on how to add logging on metrics we're interested in are
currently to patch BIND to spit out the wanted stats directly from BIND
(data on each query, perhaps aggregated). An alternative to this would
be to try to match the incoming and outgoing request and response
packets and amass the data from that, but our attempts at data gathering
through sniffing have given unreliable results. (One alternative I've
stumbled upon is DSC - http://dns.measurement-factory.com/tools/dsc/ -
but I'm not sure yet how appropriate or effective it would be for our
needs, so if anyone has any thoughts, that would be much appreciated.)
I've never worked with BIND before, so I'm looking over the code right
now figuring out which approach is going to be the most effective and
straightforward. Does anyone have any experience with something similar
and/or suggestions on approaches or considerations to think about? It's
looking like if the patch is going to be the way to go, simply modifying
BIND's stats-outputting functionality should be a good way to extend
what statistics we're getting, although I'm not sure on that count
either. Any thoughts?
Thanks, everyone
-Alex
