vnStat is a network traffic monitor for Linux that keeps a log of daily
|
|
|
|
|
network traffic for the selected interface(s). vnStat isn't a packet
|
|
|
|
|
sniffer. The traffic information is analyzed from the /proc filesystem,
|
|
|
|
|
so vnStat can be used without root permissions.
|
|
|
|
|
|
|
|
|
|
This program is open source (GPL) and can be installed in 'single' and
|
|
|
|
|
'root' mode.

Note that you can run vnstat either from cron or as a daemon from /etc/rc.d.
|
|
|
|
|
|
|
|
|
|
To run vnstat from cron:
|
|
|
|
|
Add the following line to your crontab:
|
|
|
|
|
0-55/5 * * * * if [[ -x /usr/bin/vnstat && $(ls /var/lib/vnstat/ | wc -l) -ge 1 ]]; then /usr/bin/vnstat -u; fi
|
|
|
|
|
|
|
|
|
|
To run vnstat from /etc/rc.d:
|
|
|
|
|
chmod +x /etc/rc.d/rc.vnstat
|
|
|
|
|
|
|
|
|
|
Note that to have vnstat start automatically this way it should be called from
|
|
|
|
|
rc.local (and optionally rc.local_shutdown) like so:
|
|
|
|
|
|
|
|
|
|
In rc.local:
|
|
|
|
|
# Start vnstat
|
|
|
|
|
if [ -x /etc/rc.d/rc.vnstat ]; then
|
|
|
|
|
/etc/rc.d/rc.vnstat start
|
|
|
|
|
fi
|
|
|
|
|
|
|
|
|
|
In rc.local_shutdown:
|
|
|
|
|
# Stop vnstat
|
|
|
|
|
if [ -x /etc/rc.d/rc.vnstat ]; then
|
|
|
|
|
/etc/rc.d/rc.vnstat stop
|
|
|
|
|
fi
|
