vnStat is a lightweight network traffic monitor. It keeps a network traffic log on selectable interfaces. Through the command line the network traffic statistics can be shown.
Thepackage is available in [community]:
# pacman -S vnstat
Setting the interfaces
First introduce every interface that needs to be logged to vnStat. For example a wired interface:
# vnstat -u -i eth0
Or a wireless interface:
# vnstat -u -i wlan0
When introducing an interface for the first time there will be an error message saying 'unable to read database'. If this message is followed by an info message saying 'a new database has been created' the interface is successfully introduced. If this is not the case check that the specified interface is valid.
After introducing the interface(s) set one of the update methods.
The first method is using Cron. A sample of Cron usage is provided with vnStat at
The second way of updating is using a daemon provided by vnStat. Add vnstat to your daemons in rc.conf#Daemons.
DAEMONS=(... network vnstat ...)
Other settings, like settings to control the daemon, can be done in
Query the network traffic:
# vnstat -q
Viewing live network traffic usage:
# vnstat -l
For all the other options, use:
# vnstat --help
Or for a complete list, use:
# vnstat --longhelp
