xload - system load average display for X
xload	[-toolkitoption ...] [-scale integer] [-update
  seconds]
 [-hl color] [-highlight color] [-remote host]
 [-jumpscroll pixels] [-label string] [-nolabel] [-lights]
The xload program displays a periodically updating histogram of the
  system load average.
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 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 localhost and host.
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.
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.

  - 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.
  - /usr/X11R7/lib/X11/app-defaults/XLoad
- specifies required resources
X(7), xrdb(1), mem(4), Athena StripChart Widget.
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. Therefore,
    the routine used to read it (get_load.c) must be ported to each new
    operating system.
