vnStat<\/strong><\/a> is a console-based network traffic monitor for Linux and BSD that keeps a log of network traffic for the selected interface(s). It uses the network interface statistics provided by the kernel as information source. This means that vnStat won’t actually be sniffing any traffic and also ensures light use of system resources.<\/p>\n

You can download the latest version on vnStat here<\/a>.
\n<\/p>\n

How to install vnStat:<\/strong>
\nwget http:\/\/humdi.net\/vnstat\/vnstat-1.10.tar.gz<\/code>
\n(replace vnstat-1.10<\/strong>.tar.gz with the latest version number)<\/em><\/p>\n

tar -zxvf vnstat-1.10.tar.gz<\/code><\/p>\n

cd vnstat-1.10<\/code><\/p>\n

make<\/code><\/p>\n

make install<\/code><\/p>\n

<\/p>\n

Create Database for vnStat<\/strong>:
\nEvery interface that should be monitored needs to be introduced
\n to vnStat. For that you need to create a database for every interface you want to monitor.<\/p>\n

Check for available interface names then run:
\nvnstat --iflist<\/code>
\nand select a suitable looking interface from the provided list. Usually
\n ‘lo’ isn’t the one you are looking for. For dedicated servers it should be eth0<\/strong> and venet0<\/strong> for VPS.
\n<\/p>\n

To create database for eth0:
\n\/usr\/bin\/vnstat -u -i eth0<\/code><\/p>\n

Replace ‘eth0<\/strong>‘ in the command with any available interface if needed.<\/p>\n

Repeat that for every other interface you wish to use.<\/p>\n

Set init Script for vnStat:<\/strong>
\ncp examples\/init.d\/redhat\/vnstat \/etc\/init.d<\/code>
\nchkconfig --add vnstat<\/code>
\nchkconfig vnstat on<\/code>
\nservice vnstat start<\/code><\/p>\n

vnStat should now be running on your system.<\/p>\n

Using vnStat<\/strong>:
\nAfter installation, it take some time to generate bandwidth usage stats. So you need to wait few hours before you can check the stats. During the time, vnstat cronjob runs and collect data from your server to generate the report.<\/p>\n

To see the bandwidth usage stat:
\nvnstat<\/code>
\nvnstat -d<\/code>
\nvnstat -m<\/code><\/p>\n

Here is an sample vnstat report:
