I'd put the starts in your calculation script e.g.

   DIR=/path/to/BIGDIR
   FLAG=$DIR/EEK_TOO_BIG
   LIMIT=12345678

   rm -f $FLAG || exit 3
   DIRSIZE=$(du -s $DIR | sed 's/\t.*$//')
   test $DIRSIZE -ge $LIMIT && touch $FLAG

or whatever i.e. have your calc script check the limits and
touch a file to signal that there's a problem. Your actual
nagios test is then trivial.

Cheers,
Gavin
