One of the advantages of vnStat is that it can be installed and run as a Non-Root user. This can be of a great help to query vnStat of scripts or allow operators to run the vnStat utility.
vnStat is a free OpenSource (GPL License) network traffic monitor for Linux that keeps a log of daily network traffic for the selected interface(s) on the system. Unlike other Network Traffic monitors, vnStat analyzes the traffic information from the /proc filesystem. And, vnStat can be used even without root permissions.
vnStat maintains a database for every interface for which the network traffic analysed. We can watch the live Traffic status on the selected interface(s) or run reports on Hourly, Daily, Weekly and Monthly bandwidth statics for the selected network interfaces.
