xload(1X)xload(1X)NAMExload - system load average display for X
SYNOPSISxload [-toolkitoption...] [-scale integer] [-update seconds] [-hl
color] [-highlight color] [-jumpscroll pixels] [-label string] [-nola‐
bel] [-lights]
OPTIONSxload accepts all of the standard X Toolkit command line options (see
X(1X)). The order of the options is unimportant. xload 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 xload to display the current load average by using the
keyboard leds; for a load average of n, xload lights the first n key‐
board 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, xload 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 xload updates its display. The mini‐
mum amount of time allowed between updates is 1 second. The default is
10.
DESCRIPTION
The xload program displays a periodically updating histogram of the
system load average.
RESOURCES
In addition to the resources available to each of the widgets used by
xload there is one resource defined by the application itself. 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
to get the default host and display number. to get the name of a
resource file that overrides the global resources stored in the
RESOURCE_MANAGER property.
FILES
specifies required resources
BUGS
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 sys‐
tem.
