Hi Howard, You are absolutely correct. I am already graphing / totaling the amount of traffic out the interface I just need a way to be alerted when it exceeds a particular threshold and we have to pay our ISP big bucks for going over our limit. Saves me from checking graphs each day!

It's not clear from your replies - you seem to be concerned about the size of SNMP counters which implies it's the total you a re looking for. Cacti (with it's plugin architecture and the Threshold plugin) will do this for you. If you need to alarm on total transferred, then you might need to make a new data source in Cacti - I've never wanted that particular alarm. See http://www.cacti.net/ It also does a *lot* more, so possibly is too much.
