The Display of Percent CPU in top

Submitted by wnl on Tue, 2007-07-31 11:48.Applications
The single most important piece of information processed by top is the measure of a process's percentage cpu utilization, known as percent cpu. Although top is perfectly capable of display and sorting on a variety of information, by default it sorts by percent cpu. The reason for this is that most people use top to find out what the cpu is doing, or more specifically which process is hogging the cpu. Percent cpu readily reveals this information.

Blogging about Top

When someone at a conference discovered that I was the original author for the utility "top" the reaction is always the same: "hey that's a really cool program", "thanks for writing it", or "top really saved the day". I am glad that in my own little way I was able to contribute to the system administrator's toolbox. But for years I have been unable to do much additional work with top, and it has become rather out of date. I was able to keep up with some of the operating system changes, but I have not really been able to add useful features to it or to track the seemingly endless variations that others have implemented.

Now is the time to start thinking about the annual LISA conference. This year the conference will be held in Washington DC at the Wardman Park Marriott Hotel. The conference runs from December 3 through 8. I am especially proud of this year's conference. I think we have a fine collection of speakers and papers this year, and I look forward to being your host. If you want to read more about the planning and work that is going in to LISA 06, please visit the conference blog here:
