To setup vnstat, run `vnstat -u -i en0' (replace en0 with the network
|
|
interface you wish to monitor).
|
|
|
|
You must then create a cron job to update the vnstat database.
|
|
|
|
Run `crontab -e', and add the following:
|
|
0-55/5 * * * * if [ -x #{bin}/vnstat ] && [ `ls #{var}/db/vnstat/ | wc -l` -ge 1 ]; then #{bin}/vnstat -u; fi
