# Description: A simple script to setup the pieces need to poll a router
# status page, and record the bandwidth/packet statistics. Then generate
# graphs for those values. In other words, this will allow you to generate
# usage graphs for your AT&T internet connection by polling the router.
# Tested against a Nokia BGW320-505 but it should work for AT&T router, as
# they all share the same web management interface.
# Setup Apache so the graphs can be view remotely.
