xload - system load average display for X SYNOPSIS
xload [-toolkitoption ...] [-scale integer] [-update seconds] [-hl color] [-highlight color] [-remote host] [-jumpscroll pixels] [-label string] [-nolabel] [-lights] DESCRIPTION
The xload program displays a periodically updating histogram of the system load average. OPTIONS
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 number of 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. RESOURCES
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. 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
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. FILES
/usr/share/X11/app-defaults/XLoad specifies required resources SEE ALSO
X(7), xrdb(1), mem(4), Athena StripChart Widget. BUGS
On older platforms, this program may require the ability to open and read the special system file /dev/kmem. Sites that do not allow gen- eral 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 oper- ating system. COPYRIGHT

XISDNLOAD(1) General Commands Manual XISDNLOAD(1) NAME
xisdnload - ISDN load average display for X SYNOPSIS
xisdnload[-toolkitoption ...] [-scale integer] [-update seconds] [-hl color] [-highlight color] [-online color] [-active color] [-trying color] [-activate command] [-deactivate command] [-jumpscroll pixels] [-number regexp] [-label string] [-nolabel] DESCRIPTION
The xisdnload program displays a periodically updating histogram of the ISDN load average. OPTIONS
Xisdnload accepts all of the standard X Toolkit command line options (see X(1)). The order of the options in unimportant. xisdnload also accepts the following additional options: -hl color or -highlight color This option specifies the color of the scale lines. -online color This option specifies the background color when one or more ISDN channels are online. -active color This option specifies the background color when any route is found that is directed to an interface named isdn* or ippp*. -trying color This option specifies the background color when at least one attempt to setup a cennection is pending. -jumpscroll number of 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 when beeing online. It is interpreted as a standard format string and may contain the dialed number (%s), the minutes (%d) and seconds (%d) being online, the actual cps rate (%f), the amount of kbytes transfered (%d) and a connection history (%s) in this sequence. -nolabel If this command line option is specified then no label will be displayed above the load graph. -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, xisdnload 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 xisdnload updates its display. The minimum amount of time allowed between updates is 1 second. The default is 10. -activate command This option specifies a command to be executed when dial-on-demand is not active and you clicked on the xisdnload stripchart. A typical command might be something like `sudo /etc/init.d/isdn start' to start up your connection. -deactivate command This option specifies a command to be executed when dial-on-demand is active and you clicked on the xisdnload stripchart. A typical command might be something like `sudo /etc/init.d/isdn stop' to shut down your connection. -number regexp The supplied regular expression is used to limit the set numbers to be observed by xisdnload. RESOURCES
See the resource file for the available resources. WIDGETS
In order to specify resources, it is useful to know the hierarchy of the widgets which compose xisdnload. In the notation below, indenta- tion indicates hierarchical structure. The widget class name is given first, followed by the widget instance name. XISDNLoad xisdnload Paned paned Label label StripChart load ENVIRONMENT
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. FILES
<XRoot>/lib/X11/app-defaults/XISDNLoad - specifies required resources. /proc/net/route - kernel routing table. The proc filesystem is needed by xisdnload to detect wheather a dial-on-demand is active. SEE ALSO

Besides the basic xload stuff, the ISDN parts are added by Frank Strauss <strauss@escape.de> (escape e.V., Braunschweig, Germany). In January 1998 Michael Deindl <olmur@dwarf.bb.bawue.de> contrib- uted the `yellow' patch to make xisdnload recognize the phase of trying to connect and show this by a different background color. Markus Pilzecker <mp@timesink.pilzecker.de> detected a bug in the color assignment code resulting in seg faults which has been fixed in January 1998. X Version 11 Release 6 XISDNLOAD(1)
