Except that not all errors are due to parsing problems. Sometimes
problems are caused by temporary issues with NSD itself. Sometimes
packets are unanswered due to filters, or OS issues, and so on.

Knowing what the actual application thinks it is seeing gives you a more
complete picture.

I realize people like NSD being small, but keeping it so small that you
leave out important things for administrators is probably not a good
thing... (to be fair, BIND 9 is only just now getting decent statistics,
so obviously this is not as critical as most other features).
