The vnStat utility has been developed as a network traffic monitor which is console based and available for Linux and BSD systems. The mission is to keep a record of the network traffic for the selected interface where these statistics and metrics of the network interface are provided by the kernel as a source of information. By using vnStat, we are not making use of any traffic which ensures that we will not unnecessarily use system resources affecting its operability and performance. vnStat is an open source / GPL utility and can be installed as root or as a single user with the respective permissions.

The purpose for which vnStati has been developed is to offer support for the image output of the statistics collected through the vnStat utility. The image file format can only be set as png. All basic vnStat outputs are compatible, except for live traffic functions and the result image can be sent to a file or to a standard output.

The Vnstat & Vnstati solution is installed on top of Ubuntu 18.04 installed on Azure. Tested by Apps4Rent engineers, this solution is been proven to work well on Azure.
