XLOAD(1)            UNIX Programmer's Manual             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 in 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

XLOAD(1)            UNIX Programmer's Manual             XLOAD(1)

             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 widg-
     ets 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.

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/X11R6/lib/X11/app-defaults/XLoad
          specifies required resources

BUGS

     This program requires the ability to open and read the spe-
     cial 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 permission
     flag.

XLOAD(1)            UNIX Programmer's Manual             XLOAD(1)

     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.
