vnStat is a console-based network traffic monitor. It keeps a log of hourly, daily and monthly network traffic for the selected interface(s). However, it isn’t a packet sniffer. The traffic information is analyzed from the proc(5) and sys filesystems depending on availability. That way vnStat can be used even without root permissions on most systems.<\/p>\n
