The order of the options in unimportant. \fIxload also accepts the following additional options: .PP .TP 8 .B \-hl \fIcolor\fP or \-highlight \fIcolor\fP This option specifies the color of the scale lines. .TP 8 .B \-jumpscroll \fPnumber of pixels\fP 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. .TP 8 .B \-label \fIstring\fP The string to put into the label above the load average. .TP 8 .B \-nolabel If this command line option is specified then no label will be displayed above the load graph. .TP 8 .B \-lights When specified, this option causes .I xload to display the current load average by using the keyboard leds; for a load average of \fIn\fP, xload lights the first \fIn\fP keyboard leds. This option turns off the usual screen display. .TP 8 .B \-scale \fIinteger\fP 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, \fIxload\fP will create more divisions, but it will never use fewer than this number. The default is 1. .PP .TP 8 .B \-update \fIseconds\fP This option specifies the interval in seconds at which \fIxload\fP updates its display. The minimum amount of time allowed between updates is 1 second. The default is 10. .TP 8 .B \-remote \fIhost\fP This option tells \fIxload\fP to display the load of \fIhost\fP instead of \fIlocalhost\fP. \fIXload\fP gets the information from the \fIrwhod\fP database and consequently requires \fIrwhod\fP to be executing both on \fIlocalhost\fP and \fIhost\fP. .SH RESOURCES In addition to the resources available to each of the widgets used by \fIxload\fP there is one resource defined by the application itself. .TP 8 .B showLabel (\fPclass\fB Boolean) If False then no label will be displayed. .SH WIDGETS In order to specify resources, it is useful to know the hierarchy of the widgets which compose \fIxload\fR. In the notation below, indentation indicates hierarchical structure. The widget class name is given first, followed by the widget instance name. .sp .nf .ta .5i 1.0i 1.5i 2.0i XLoad xload Paned paned Label label StripChart load .fi .sp .SH ENVIRONMENT .PP .TP 8 .B DISPLAY to get the default host and display number. .TP 8 .B XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. .SH FILES .TP .I __apploaddir__/XLoad specifies required resources .SH SEE ALSO X(__miscmansuffix__), xrdb(1), mem(4), Athena StripChart Widget. .SH BUGS This program requires the ability to open and read the special system file \fI/dev/kmem\fP. Sites that do not allow general access to this file should make \fIxload\fP belong to the same group as \fI/dev/kmem\fP and turn on the \fIset group id\fP permission flag. .PP 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. .SH COPYRIGHT Copyright \(co X Consortium .br See \fIX(__miscmansuffix__)\fP for a full statement of rights and permissions. .SH AUTHORS K.
