What is vnStat :::::::::::::: 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. Traffic statistics are stored on a hourly level for the last 24 hours, on a daily level for the last 30 days and on a monthly level for the last 12 months. Total seen traffic and a top 10 days listing is also provided. Optional png image output is available in systems with the gd library installed. See the webpage http://humdi.net/vnstat/ for output examples. Getting started ::::::::::::::: vnStat works best when installed. See the INSTALL or INSTALL_BSD file depending on used operating system. Experimental instructions for OS X are available in the INSTALL_OSX file. These files contain all needed information for the installing process. Instructions for upgrading from a previous version are included in the UPGRADE file. Available options and documentation ::::::::::::::::::::::::::::::::::: A list of commonly used options is available with 'vnstat --help'. The complete list can be accessed with 'vnstat --longhelp'. The following man pages are available with more detailed descriptions of each option including some usage examples: vnstat general documentation and console query parameters vnstatd daemon documentation vnstati image output documentation vnstat.conf configuration file Usage tips :::::::::: Most vnStat settings can be changed from the config file. The config file is either ~/.vnstatrc or /etc/vnstat.conf depending which one is found first. A new config file can be generated using current settings with the following command: vnstat --showconfig >newconfig The config file contains comments before any settings describing with the purpose and usage of each setting is.
