NAME
       xload - system load average display for X

SYNOPSIS
       xload     [-toolkitoption  ...] [-scale integer] [-update seconds] [-hl
       color] [-highlight color]  [-remote host]
               [-jumpscroll pixels] [-label string] [-nolabel] [-lights]

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(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.

       -nolabel
               If this command line option is specified then no label will  be
               displayed above the load graph.

       -lights 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.

       -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  local-
               host and host.

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.

       XLoad  xload
               Paned  paned
                       Label  label
                       StripChart  load


ENVIRONMENT
       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/share/X11/app-defaults/XLoad
              specifies required resources

BUGS
       On older platforms, this program may require the ability  to  open  and
       read  the  special system file /dev/kmem.  Sites that do not allow gen-
       eral access to this file may need to make  xload  belong  to  the  same
       group as /dev/kmem and turn on the set group id permission flag.

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