ps aux | grep vnstat" in a terminal
You should see a line like this:
root 1091 0.0 0.0 1956 596 ? Ss 17:21 0:00 /usr/sbin/vnstatd -d
If not, it means the update daemon is not running.
- the computer was not rebooted since you installed vnstat
- the daemon is not installed (type "
ll /etc/init.d/vnstat" and check that no error message is returned)
As soon as the daemon is running with default settings, you will have updates of stats every 5 minutes.
Just type "
vnstat" at 5 minutes intervall to validate (check the first line
"Database updated ")
