vnStat is a console-based network traffic monitor that uses the network interface statistics provided by the kernel as information source. This means that vnStat won't actually be sniffing any traffic and also ensures light use of system resources. vnStat had an Initial public release in 23-Sep-2002 (version 1.0) by Teemu Toivola.
On 8 March 2004 its webpage moved to https://humdi.net/vnstat/ and a man page was included.
On 4 November 2006 was included in Debian for Testing Watch [4] and on 17 November 2006 was removed and next day was accepted 1.4-4 version.
On 20 February 2010 was accepted 1.10-0.1 version in Debian.[5] Nowadays Debian keeps a full history[6] about vnstat by using a Rich Site Summary.
On 26 April 2012 was included in Ubuntu 12.04 Precise Pangolin [7]
On 16 February 2017 a 1.17 version was released.[8]
