The you can use it this way:

# Start nethogs on the default network interface

apt-get install -y vnstat

Now to use it execute the command line:

#Show live trafic
vnstat -l
# Start monitoring the trafic
vnstat -u -i eth0
# Check your daily traffic (but you need to start   the monitoring and gather the data before you can use it)
vnstat -d
# Monthly
