 I missed the original posting, but I'd also put in a plug for looking 
 at the DNS-OARC "DNS Tools" web site, 
 https://www.dns-oarc.net/oarc/tools, for lots of nifty little tools.  
 Many/most/all of these can easily be used to collect the information 
 that you are looking for.

 I would also suggest the Measurement Factory, 
 http://dns.measurement-factory.com/tools/, for other tools.  I am 
 extremely impressed with their "dnstop" utility which really easily 
 identifies the most frequent queries.  I don't think that it will report 
 lookup failures for you, but I could easily be wrong.

 Either of these, set up as a daily, periodic, job could easily produce 
 the information that you are asking for.

 I'm very biased in that I would much prefer to NOT have to enable query 
 logging to determine these statistics.  Using the DNS-OARC dnscap 
 utility, and the Measurement Factory, dnstop, utility, both operate as 
 packet capture tools that don't have to require lots of disk space for 
 log files to store stuff that is not always needed.
