vnstati is a command-line tool that provides PNG image output support for vnStat, a console-based network traffic monitor. vnstati allows users to generate static images of vnStat network traffic statistics, which can be used for visualizing and analyzing network traffic usage over time.
vnstati works by reading the data generated by vnStat and generating PNG images that represent the network traffic usage over a specific time period, such as hourly, daily, weekly, monthly, or yearly. vnstati provides a variety of options and settings for generating these images, such as the size of the output image, the time period to cover, the data source to use, and the output format.
