Description

This is an AfterStep look & feel CPU statistics monitor tool for computers running Linux, FreeBSD, HP-UX or AIX.

I just got fed up once that all the AfterStep applets are so unconfigurable and decided to write my own so that I have the different look the way I want it :) The first to go was asload as the simplest. Now it does not contain any code (I think so) from asload and is written from scratch by truly yours.

What you see on the display:

        The right (big) area displays the current load on
        the CPU or rather the load on the CPU during the
        last update period. Default update period is 1 sec
        but you can change that. The load is divided into
        three parts: system CPU time (bright), nice CPU
        time (medium), and the user CPU time (dark).
        The consumed CPU time is displayed in percents of
        total (plus idle time that is) CPU time passed.

        On the left side you have an indicator that shows
        the same values taken average over a number of samples.
        The default number of samples is 60. This means
        with the default setting of update rate once a second
        you see the average CPU load during the last minute.

Ok, you see, Cory Visi got me into this mess so it is not my fault. Anyways, what you just read above is ok, though you can use this thing "the other way around". That is, you can give a small number of samples to the "average indicator" and a big number of samples to the "running history window". In that case the average value will be updated more often than the running history. For example, if you take a value of 1 for the number of samples for the average it will show you the actual load on the CPU at this moment. And you can at the same time give the value of, let's say, 60 to the running history window. Then the running history will actually show you average loads over 1 minute periods.

So, there are two exactly opposite ways of running the widget. But I am glad to have implemented them :)

ascpu contains some code from asapm utility. Do I have to give credit to myself? :-) There is some stuff for working with X windows that I inherited from asapm tool and that initially comes from some place else. See asapm for credits too.
