==> Caveats
To monitor interfaces other than "en0" edit /usr/local/etc/vnstat.conf

To have launchd start vnstat now and restart at startup:
  sudo brew services start vnstat
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/vnstat/bin/vnstatd --nodaemon --config /usr/local/etc/vnstat.conf
