xload - system load average display for X
xload [-toolkitoption...] [-scale integer] [-update seconds] [-hl color] [-highlight color] [-jumpscroll pixels] [-label string] [-nolabel] [-lights]
accepts all of the standard X Toolkit command
line options (see
X(1X)). The order of the options is unimportant.
also accepts the following additional options:
This option specifies the color of the scale lines.
The number of pixels to shift the graph to the left when the
graph reaches the right edge of the window. The default value is 1/2 the
width of the current window. Smooth scrolling can be achieved by setting
it to 1.
The string to put into the label above the load average.
If this command line option is specified then no label will
be displayed above the load graph.
When specified, this option causes
to display the current load average by using the keyboard leds; for a load
keyboard leds. This option turns off the
usual screen display.
This option specifies the minimum number of tick marks in
the histogram, where one division represents one load average point. If the
load goes above this number,
will create more divisions,
but it will never use fewer than this number. The default is 1.
This option specifies the interval in seconds at which
updates its display. The minimum amount of time allowed between
updates is 1 second. The default is 10.
program displays a periodically updating
histogram of the system load average.
In addition to the resources available to each of the widgets used by
there is one resource defined by the application itself.
If False then no label will be displayed.
In order to specify resources, it is useful to know the hierarchy of the widgets which compose xload. In the notation below, indentation indicates hierarchical structure. The widget class name is given first, followed by the widget instance name.

This program requires the ability to open and read the special system file /dev/kmem. Sites that do not allow general access to this file should make xload belong to the same group as /dev/kmem and turn on the set group id permission flag.

Therefore, the routine used to read it (get_load.c) must
be ported to each new operating system.
