NAME
     xload - system load average display for X

SYNOPSIS
     /usr/bin/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(5)).  The order of the  options  is  unimpor-
     tant.  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 repre-
             sents 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.

RESOURCES
     In  addition  to the resources available to each of the wid-
     gets 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  nota-
     tion  below,  indentation  indicates hierarchical structure.
     The widget class name is given first, followed by the widget
     instance name.

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  general 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.  There-
     fore, the routine used  to  read  it  (get_load.c)  must  be
     ported to each new operating system.
