NAME    [Toc]    [Back]

       xload - system load average display for X

SYNOPSIS    [Toc]    [Back]

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

OPTIONS    [Toc]    [Back]

       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.

DESCRIPTION    [Toc]    [Back]

       The xload program displays a  periodically  updating  histogram
 of the system load average.

RESOURCES    [Toc]    [Back]

       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.

WIDGETS    [Toc]    [Back]

       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.

ENVIRONMENT    [Toc]    [Back]

       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.

FILES    [Toc]    [Back]

       specifies required resources

BUGS    [Toc]    [Back]

       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
       permission flag.

       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.
