ipac (if you use ipchains) or ipac-ng (if using iptables).

Then you can use the ipacsum command to generate a report. If you are
only interested in the total traffic you could use something like:

root@spiderwebs:~#ipacsum -t "this month" --filter "all" --fixed-quantity ''
IP accounting summary
Host: spiderwebs / Time created: 2002/10/28 11:10:42 CE
Data from 2002/10/01 01:00:00 CE to 2002/10/28 11:10:42 CE
  total in all                                    :      4317454231
  total out all                                   :      4328291196

With a bit of perl or awk it's not difficult to calculate whether this
is below or above your 80% threshold and decide if an email should be
sent.
