xload - system load average display for X
xload [-toolkitoption...] [-scale integer] [-update seconds]
[-hl color] [-highlight color] [-jumpscroll pixels]
[-label string] [-nolabel] [-lights]
xload 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 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, 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 minimum amount of time
allowed between updates is 1 second. The default is 10.
The xload program displays a periodically updating histogram
of the system load average.
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.
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.
specifies required resources
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
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.
