Rob,
we wrote a perl script that scans the mrtg automatically-generated web
pages and compares todays Average to yesterday's Average and then sends an
e-mail if the diferences is over 3x. This is done every day. If you
wanted you could do a similar script, checking every 5 minutes for the
'current in' verses a monthly 'average' and send email acordingly.
Scanning the text in the automatically created html page allows you to
create any custom crafted rules.
