Monitor Bandwidth Usage with vnStat

Monitor Bandwidth Usage with vnStat - Linux Magazine Online: "In these days of bandwidth caps and pay-per-kilobyte rates, keeping an eye on your bandwidth usage makes a lot of sense. While there is no lack of bandwidth monitoring utilities, vnStat stands out from the crowd thanks to its ability to store monitoring data in a database and resume monitoring automatically on reboot. This means that once installed and configured, vnStat quietly monitors a specified network interface and saves the collected data. You can then use vnStat's command parameters to view detailed reports of your bandwidth usage."
