xload --
load average display for X
Syntax
xload [-toolkitoption...] [-scale
integer] [-update seconds]
[-hl color] [-highlight color]
[-jumpscroll pixels]
[-label string] [-nolabel]
Description
The xload program displays a periodically
updating histogram of the system load average.
Options
xload
accepts all of the standard X Toolkit command line options (see
X(X)
The order of the options in unimportant.
xload also accepts the following additional options:
-hl color or -highlight color-
This option specifies the color of the scale lines.
-jumpscroll number of pixels-
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.
-label string-
The string to put into the label above the load average.
-nolabel-
If this command line option is specified then no label will be
displayed above the load graph.
-scale integer-
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 xload will create
more divisions, but it will never use fewer than this number.
The default is 1.
-update seconds-
This option specifies the frequency in seconds at which
xload updates its display.
The minimum amount of time allowed between updates
is 1 second (the default is 5 seconds).
Resources
In addition to the resources available to each of the widgets used by
xload there is one resource defined by the application itself.
showLabel (class Boolean)-
If False then no label will be displayed.
Widgets
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.

Environment variables
DISPLAY-
to get the default host and display number.
XENVIRONMENT-
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
Files
/usr/lib/X11/app-defaults/XLoad specifies required resources
Known limitations
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.
Reading /dev/kmem is inherently non-portable.
Therefore, the routine used to read it (get_load.c)
must be ported to each new operating system.
