program displays a periodically updating histogram of the system load average.
accepts all of the standard X Toolkit command line options (see X(7)).
The order of the options is 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.
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 average of n, xload lights the first n keyboard leds.
This option turns off the usual screen display.
- -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 interval in seconds at which xload
updates its display. The minimum amount of time allowed between updates
is 1 second. The default is 10.
- -remote host
This option tells xload to display the load of host instead of localhost. Xload gets the information from the rwhod database and consequently requires rwhod to be executing both on localhost and host.
In addition to the resources available to each of the widgets used by
there is one resource defined by the application itself.
- showLabel (class Boolean)
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.
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.

On older platforms, this program may require the ability to open and read
the special system file /dev/kmem
. Sites that do not allow general
access to this file may need to make xload
belong to the same group
and turn on the set group id
Reading the load average is inherently non-portable. Therefore, the routine
used to read it (get_load.c) must be ported to each new operating system.
