Cacti

Cacti is an open source, web-based graphing tool designed as a frontend to RRDtool’s data storage and graphing functionality. It is generally used to graphtime-series data of metrics such as CPU load and network bandwidth utilization. A common usage is to monitor network traffic by polling a network switch or router interfacevia SNMP.

I want to use it to display bandwidth statistics for my customers.
