NAME

ServDoc - give you a complete (?) Documentation of all the hard- and software on your system

VERSION

$Id: ServDoc,v 1.9 2004/01/03 20:43:25 uherbst Exp $

SYNOPSIS

ServDoc [-h|help] [-v|version] [--debug feature,intensity] [--output_format ascii|html]

DESCRIPTION

ServDoc runs a variety of checks and gives the output in different formats to you.

The goal of ServDoc is a oneshot-online-documentation of your whole system with all the hardware, all the software, all the configurations, all the batch-jobs and so on.

To archive this goal ServDoc is written very modular to allow easy extensions of your special software.

OPTIONS

-h|help

This help.

-v|version

Version

--debug feature,intensity

Turn on Debugging for that feature with that intensity.

Every ``feature'' is a part of ServDoc, a module, a submodule or something like that. ``intensity'' is a integer number between 0 and 9. 0 means no debug output, 9 means very much debug output.

The feature ``ALL'' stands for all features.

You can find a list of all features in [SERVDOC_HOME]/doc/README.debugfeaturelist or in the userguide.

To configure more than one feature, you can give that option more then once.

do_all_modules

  @output=do_all_modules($options,$module_path);

Execute all modules in module_path and collect the output.

The modules sit in module_path and there filename starts with ``ServDoc_''. For unix systems, the ServDoc_ - modules have to have the x-right. For windows this is not necessary.

Only modules in $module_path will be executed. Modules in Subdirectories won't be executed.

$options has to be a hash reference. $options->{cmdline} has to be a string with the debug options from the commandline.

The modules will be called as arguments to the same perl executable as ServDoc is called with. (with other words: every module called with do_all_modules can be a perl script! (perl evalutes the Shebang-Line (#!/bin/sh) and therefor perl calls that shell if needed))

If there are more than one module named ``ServDoc_xxx--<OSNAME>'' where <OSNAME> something like ``aix'',``linux'',... is, than only the module with the correct OSNAME (look at $OSNAME in your perl) is executed.

If there isn't a ServDoc_xxx--<OSNAME> with the correct OSNAME, then ServDoc_xxx--other is executed (if exists).
