XLOAD(1)										 XLOAD(1)

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  win-
	       dow.  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 key-
	       board 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.

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.

	    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 sys-
       tem 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.  Therefore, the routine used to read
       it (get_load.c) must be ported to each new operating system.
