Looking for a program to monitor bandwith

[Myth]

Not sure if this is the right categorie to ask, but:

I'm looking for a small tool that keeps track of my server's total monthly traffic (so not just apache for example. Upload and download however i prefer to have seperated.). The results have to end up on a webpage eventually, but i don't quite care if its a graph or just plain text. As long as it's easy to read.

I been looking on the web and have found multiple tools that might be able to do just that, but most of them have such advanced feature list that i'm not quite sure if it's really made for the thing i want (for example: most tools monitor the bandwith that goes through your local router instead of the server itself, or other tools give you a minute by minute graph that only keeps track of the total for 24 hours.). It might be able to configure them for what I need, but perhaps there are better alternatives out there.

Any recommendations?

For total data in / out I use vnStat in combination with vnstat PHP frontend

It's easy to setup, and all needed info can be found on the websites!
