.SH DESCRIPTION
|
||
|
|
The
|
||
|
|
.I xload
|
||
|
|
program displays a periodically updating histogram of the system load average.
|
||
|
|
.SH OPTIONS
|
||
|
|
.PP
|
||
|
|
.I Xload
|
||
|
|
accepts all of the standard X Toolkit command line options (see \fIX(__miscmansuffix__)\fP).
|
||
|
|
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.

|
.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.
