xisdnload: ISDN load average display for X

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.

-manual

With this option the interface is assumed to be active and in manual dial mode. The activate/deactive commands are selected depending on the connection state. A typical activate command might be `isdnctrl dial ippp0', and to deactivate `isdnctrl hangup ippp0'.

-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, indentation 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.

BUGS

Certainly a lot.

AUTHORS

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