Three Steps to Find Your Total Download Bandwidth Usage

I have been working on bandwidth-monitoring of late, and I find the following three steps handy to find my download byte count. These steps use iptables, which is available with almost all distributions. It most likely already will be installed on your system (it is the basic firewall in Linux).

Steps one and two set up the monitoring, and step three allows you to view your download byte count. The first two steps need to be done only once (at boot time, if you want this available all the time). You need to run all the steps as root.

Step 1: create a chain:

$ iptables -N input_accounting

This creates an iptables chain named input_accounting.

Step 2: add a rule:

$ iptables -I INPUT -j input_accounting

This causes all incoming packets to “pass through” your newly created chain.

Step 3: start checking your bandwidth:

$ iptables -L -v | \
		grep input_accounting | \
		grep anywhere | \
       	awk '{ printf("%s\n", $2) }'

This should output your download byte count—for example, “500K”.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
