sudo apt-get install vnstat<\/pre>\n
2. find out your interface name<\/h3>\n

3. Configuration<\/h3>\n
sudo vi \/etc\/vnstat.conf<\/pre>\n
Interface \"enp0s31f6\"  => Interface \"eth0\"\r\n\r\n<\/pre>\n
4. A new database create \/ vnstat –create -i eth0<\/h3>\n
$ vnstat --create -i eth0\r\n<\/pre>\n
$ vnstat -d\r\nNo database found, nothing to do. Use --help for help.\r\n\r\nA new database can be created with the following command:\r\n    vnstat --create -i eth0\r\n\r\nReplace 'eth0' with the interface that should be monitored.\r\n\r\nThe following interfaces are currently available:\r\n    eth0 lo\r\n$ vnstat --create -i eth0\r\n<\/pre>\n
5. Now, make vnstat daemon auto start at boot<\/h3>\n
sudo systemctl start vnstat.service\r\nsudo systemctl enable vnstat.service<\/pre>\n
6. check \/ vnstat -h<\/h3>\n
