xload(1X) xload(1X) NAME xload - system load average display for X SYNOPSIS xload [-toolkitoption...] [-scale integer] [-update seconds] [-hl color] [-highlight color] [-jumpscroll pixels] [-label string] [-nola- bel] [-lights] OPTIONS 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 la- bel will be displayed above the load graph. When specified, this op- tion causes xload to display the current load average by using the key- board 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 The xload program displays a periodically updating histogram of the system load average. RESOURCES 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 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. XLoad xload Paned paned Label label StripChart load ENVIRONMENT to get the default host and display number. to get the name of a re- source file that overrides the global resources stored in the RE- SOURCE_MANAGER property. FILES specifies required resources BUGS 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 sys- tem. COPYRIGHT Copyright 1988 X Consortium See X(1X) for a full statement of rights and permissions.
