If you want to monitorize your bandwidth on your Rackspace Cloud Server or any other server all you have to do is to run this script and the script will automagically send you notifications when you will reach the limit you established.

Requirements :

• postfix (or any other MTA)
• screen (the script is running in a screen. This is a MUST)
• vnstat (is used to check the bandwidth)

Installing dependencies :

Ubuntu / Debian Distro : apt-get install postfix vnstat screen CentOS / RedHat / Fedora & Co : yum install -y postfix vnstat screen

Usage :

• wget https://raw.github.com/mariusv/bandwidth-monitoring/master/bandwidth.sh
• edit bandwidth.sh and go to MAX =’10’ line and just replace 10 with the maximum value you want(the value MUST be in MB)
• chmod +x bandwidth.sh
• ./bandwidth.sh (the script will start a new screen session and as soon as you reached the limit you established will send you an alert email)
