The /proc File System And ProcMeter

You may rely on your electronic Rolodex to organize your life, but Linux uses the /proc file system.
How Can ProcMeter Help?

I have a ProcMeter window permanently open occupying the right-hand edge of the screen. Most of the time it is just taking up space, but there are times when it can be very useful.

When getting files via FTP from the Internet, the amount of packets sent and received can be monitored. When the packets stop coming, the transfer is finished or stuck. This is a good time to ping the FTP site to see if the route is still open.

Have you ever felt that the program you have just written is taking too long to run? This could be a symptom of running out of RAM and using swap space. Try looking at the mem-used, mem-free, mem-swap and swap graphs. A steeply rising graph will indicate a memory leak.

Where to Get ProcMeter

The latest version of ProcMeter is version 2.1, available as source code by FTP from sunsite.unc.edu. The file is called procmeter-2.1.tgz, and is in the directory /pub/Linux/X11/xutils/status. Alternatively, if you have WWW access, the latest information about ProcMeter is available on my home page at http://www.gedanken.demon.co.uk/, along with links to other sources for the program.

Andrew Bishop has been using Linux for 2 years. The original version of ProcMeter was the first program he wrote using Linux. He programs mainly in C, Perl and Emacs Lisp on Unix systems, often inventing his own version of the wheel as he goes. He can be reached by e-mail at ambi@gedanken.demon.co.uk.

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.
