I am using Ubuntu 10.10 Maverick Meerkat and I installed vnstat v1.10-1 from the terminal using apt-get:
sudo apt-get install vnstat
The installation ended with an error:
* Starting vnStat daemon vnstatd Zero database found, exiting.
[fail]
When I tried to monitor my traffic using the following command:
vnstat -m -i eth0
I got the following error:
Error: Unable to read database “/var/lib/vnstat/eth0”.
Then I ran vnstat from the command line and got the following:
No database found, nothing to do. Use –help for help.
A new database can be created with the following command:vnstat -u -i eth0
Replace ‘eth0’ with the interface that should be monitored.
The following interfaces are currently available:lo eth0 vboxnet0
Since my computer is using eth0, I created a database for eth0 using the following command:
sudo vnstat -u -i eth0
I got the following output:
Error: Unable to read database “/var/lib/vnstat/eth0”.
Info: -> A new database has been created.
Now, I am able to monitor my Internet traffic using vnstat.
