For me, it would be a great advantage, to have the option to log requests and
reponses only, both DHCP and DNS, but omitting intermediate steps. This might
be made more flexible, like defining sections of code to be logged only, as in
squid. Or setting up classes of logs, like"debug" (as it is like "log-queries"
right now) and a more quiet, new "log-queries" only logging queries and
responses.

Hi all, maybe the OP should clarify what he wants to do. Just to unclutter
a log for debugging, the standard tools are fine (grep&c.).
Or does he parse the logs for another goal? Then, a terser format might
make sense - or a completely different approach.
Best,

Hi Richard,
The question is about controlling what is logged, not where it is (and
no, I don't have any idea except poor man's solutions such as filtering
the whole log -- wherever it comes from -- through grep plus tailf).
Ammicalement,
Albert.
