I have had good success with Netflow data to solve this, and if you don't mind spending a little money, Scrutinizer is a good tool to use.

MRTG provides graphs of usage, but I'm not aware of it providing a monthly total usage (or 95% or other) in report form (though would be happy to learn otherwise).
Does ntop provide a way to generate a monthly report?
I believe the others posting are interested in this from a billing perspective. I share their interest.
Cacti and MRTG both have support for rrdtool backends. How the rrd is processed is up to you. A simple script to poll data and do some basic math and email the results, or generate a graph. Cacti has several plugins for sending reports. MRTG users tend to just script additionals. It's not as gui oriented as cacti, IMO. Each has pros and cons. If you have a sound internal php/mysql setup, cacti is a breeze and the plugin php scripts are cute for the non-techies. -Jack -- THIS E-MAIL MESSAGE AND ANY FILES TRANSMITTED HEREWITH, ARE INTENDED SOLELY FOR THE USE OF THE INDIVIDUAL(S) ADDRESSED AND MAY CONTAIN CONFIDENTIAL, PROPRIETARY OR PRIVILEGED INFORMATION.
