xload 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
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
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 keyboard leds. This option turns off the usual
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
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.
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
In addition to
the resources available to each of the widgets used by
xload there is one resource defined by the

In order to

widgets which compose xload. In the notation below,

load average is inherently non-portable. Therefore, the
routine used to read it (get_load.c) must be ported to each
new operating system.
