This is a perfect example of MRTG. DSLReports graphs incoming and outgoing traffic. This, however, is only one of many things MRTG can do.
More from http://people.ee.ethz.ch/~oetiker/webtools/mrtg/mrtg.html:
MRTG consists of a Perl script which uses SNMP to read the traffic counters of your routers and a fast C program which logs the traffic data and creates beautiful graphs representing the traffic on the monitored network connection. These graphs are embedded into webpages which can be viewed from any modern Web-browser.
In addition to a detailed daily view, MRTG also creates visual representations of the traffic seen during the last seven days, the last five weeks and the last twelve months. This is possible because MRTG keeps a log of all the data it has pulled from the router. This log is automatically consolidated so that it does not grow over time, but still contains all the relevant data for all the traffic seen over the last two years. This is all performed in an efficient manner. Therefore you can monitor 200 or more network links from any halfway decent UNIX box.
MRTG is not limited to monitoring traffic, though. It is possible to monitor any SNMP variable you choose. You can even use an external program to gather the data which should be monitored via MRTG. People are using MRTG, to monitor things such as System Load, Login Sessions, Modem availability and more. MRTG even allows you to accumulate two or more data sources into a single graph.

This guide is the best way to start an installation. If you run into issues, feel free to start a thread about it in the forums.

This page offers a very good walkthrough on setting up MRTG for UNIX.

MRTG relies on SNMP to grab data, so if your device can communicate using SNMP, there is a very good chance that MRTG will work.
A compatibility list can be found at the official MRTG site.
