Would that make you happy?
A logging category that logged not just incoming queries, but also outgoing queries, and also the responses sent/received to these queries, would be really handy. It doesn't need to log the whole packet (except at some debug level), but just something along the lines of the current logging category. For responses, also log the type of response: positive answer, nxrrset (or whatever you want to call this), nxdomain, referral, or error (with type). This category could either log all of this at info level, or else log incoming queries at level notice and all other traffic at level notice. Or even log incoming queries at level info and all other traffic at debug level 1 (to retain current behavior for non-debug levels), and then start logging full packet contents (i.e. what we see in default dig output) at higher debug levels. I see this as a replacement for the current queries logging category, not an addition to it. While we're on the topic of logging, if somebody could write up a set of documentation of all of the current (at least non-debug) log messages and add it to the ARM, that would be great. I would rather not dig through source code looking for explanations when the log message itself is not perfectly clear. Chris Buxton Professional Services Men & Mice
