Use it like this below:

vnstat -u -i interface forces a database update for interface or creates the database if it doesn't exist. This is
       usually the first command used after a fresh install.

       vnstat  -u  -i interface --nick nick gives interface the nickname nick and that information will be later included
       with queries.

       vnstat -u -r --disable -i interface resets the internal counters of interface and disables it from  being  updated
       before  enabled again with the --enable parameter. This feature is especially useful for interfaces like ppp0 that
       aren't always active.

And one of out put will be below,

sudo /usr/bin/vnstat -l
Monitoring ppp0...    (press CTRL-C to stop)
