I think I understand my problem now. In my own words: all signatures
are set to have a validity of 14 days - the period I want to check in
Nagios. This does not work, because only signatures are re-generated,
that are going to expire in the resign period. If I set the resign to
e.g. 12 days, the signer will resign the whole zone every two days. This
will consume more CPU and scale bad with many zones.

If I just have a few zones, I can set signature validity to 14, Resign
to 10. This will cause all 4 days a resign. Signature expire should not
fall below 10 days with this (minus 3 hours). Correct? So e.g. nine days
would be safe to check in Nagios.
