=head1 DESCRIPTION
B<Indexmaker> can create web pages which display the status of an
array of mrtg interface status pages.
=over
=item B<--output> I<filename>
set output filename (default: stdout)
=item B<--filter> (B<title>|B<pagetop>|B<name>)(B<=~>|B<!~>)I<regexp>
Several filters may get set. Each filter can match agains the contents
of a specific section of the mrtg config file. B<Name> refers to the
bit in square brackets (option[name]: bla).
Depending on the match operator chosen (B<=~> or B<!~>) the match will be
positive or negative.
Note that some shells consider B<!> a special character. It may be
necessary to type B<\!~> instead.
=item B<--title> I<text>
Set title of generated index file (default: regexp)
=item B<--bodyopt> I<text>
The value of this argument gets appended to
the E<lt>BODYE<gt> tag. This allows you to set document colors.
By default this option is set to
bgcolor="#ffffff" text="#000000" link="#000000" vlink="#000000" alink="#000000"
=item B<--columns> I<number>
Display graphs in a table with I<number> columns (default: 2)
=item B<--sort> B<title>|B<name>|B<descr>|B<original>
Sort the graphs in the page either by B<title>, by B<name>, by interface
B<descr>iption, or leave them as is.
=item B<--enumerate>
Add a sequence number to the title of each graph
=item B<--width> I<number>
Set width of graphs
=item B<--height> I<number>
Set the height of the graphs
=item B<--show> B<day>|B<week>|B<month>|B<year>|B<none>
Select which graph to show in the index page. You can supress images
completely with B<--show=none>.
=item B<--section> B<h1>|B<title>|B<name>|B<description>|B<portname>
Select what to use as the title for each graph in the page. B<h1> is
the H1 section from pagetop, B<title> is the graph title, B<name> is
the bit in square brackets (option[name]: bla), and B<descr> or
B<description> is the text from the Description field of the PageTop
(the Cisco description text if it's available, otherwise just the
interface description). B<portname> is the C<Port Name:> from pagetop.
=item B<--sectionhost>
Extract the hostname from the target line (this does not work if the
target is a mathematial expression). Prepend the hostname (and a colon)
to the section if not already present.
=item B<--rrdviewer> I<path>
If you have set the B<LogFormat: rrdtool> property in the mrtg.cfg
file, the index will take this into account. The only thing you must
tell it is the path to your grapher cgi. (default: /cgi-bin/14all.cgi)
=item B<--prefix> I<path>
By default we assume that the file generated by indexmaker is stored in
I<WorkDir>. If you want to store it somewhere else, specify how to reach
I<WorkDir> from the place where the Index is stored. Note that you have to
use '/' as path separator as this will be used in urls. Speaking of which,
you can even enter a whole url.
=item B<--autoprefix> I<path>
Requires --output.
Try to generate the prefix automatically by comparision of the path to the
output file set with --output and the Htmldir set in the configuration files.
Particulary useful when multiple configuration files are specified, with
different Htmldir settings.
=item B<--optlog>
Default is logging in the generated page the command line, suppress with
--nooptlog . Useful if the commandline contains a complex --pagetop=string
which could confuse simple browsers.
=item B<--someoption-file> I<filename>
For any someoption which takes a I<string> as parameter you can read the
string from a file by adding <-file> to the option keyword. The whole
content of the file will be read and used as the I<string>. The file must
exist.
