=head1 NAME
weathermap.pl - A Network Weathermap script for Hobbit/Xymon and Devmon
=head1 SYNOPSIS
-c, --config=FILE configuration file or directory of configuration files
-o, --output=FILE output image file (or directory in the case of multiple maps)
to write to
-s, --scale=INT Scale the entire map by an integer value (for large displays)
-f, --font=FILE Default TTF font to use (for FONTS 1-5 when scaled)
-t --theme Theme color to use (white|black, default white)
-v, --version print version
-h, --help print this text
-d, --debug enable debug output
--htmloutput=FILE enable HTML output to FILE, or a directory
--image-uri=URI use URI for the IMG tag when generating HTML
--icondir=DIR Directory where node icons are to be found
=head1 DESCRIPTION
weathermap.pl is a perl script to generate a weathermap-like diagram of a network.
This version, derived from Network Wearthermap - version 1.1.1 (20040422), available at
L<http://netmon.grnet.gr/weathermap/>, has been modified as follows:
=over
=item *
All data required to generate values (e.g. link utilisation) is queried from
Hobbit/Xymon. By default, link values will be determined from the table entry
in the if_load test that matches the INTERFACES value provided in the map
configuration file for that end of the link. Additionally, the "overlib"
popups over links will include the link description (if available to devmon).
Thus, the default behaviour should work well with a Hobbit/Xymon and Devmon
setup monitoring network devices, and should require much less configuration
(and significantly easier, if you are happy to edit config files) than most
other weathermap implementations.
=item *
By default, an overlib graph of the CPU utilisation of the device is offered
for mouseover events on devices.
=item *
Support for the majority of the configuration file syntax used by PHP Weathermap
(from L<http://www.network-weathermap.com>) has been added.
=item *
If all the options that take a file name are directories, all configuration
files with name ending in .conf will be processed, and the image and output
file names will be the part of the file name preceding .conf. E.g., if
the options -c /etc/xymon/weathermap -o /var/lib/xymon/www/weathermap are used,
and /etc/xymon/weathermap contains lan.conf and wan.conf, maps will created
for each, as lan.html with lan.png, and wan.conf with wan.png respectively.
=item *
Defaults for a number of options are taken from Xymon/Hobbit environment
variables, for good default operation from the hobbitlaunch.
=back
=head1 CONFIGURATION FILE SYNTAX
The configuration file consists of global options, then NODE and LINK sections.
PHP Network Weathermap configuration directives (L<http://www.network-weathermap.com/manual/latest/pages/config-reference.html>)
and their support status in this script:
=head2 NODE options
NODE <nodename> Must be hostname used by Xymon/Devmon
POSITION x y y
LABEL labeltext y Name that will be displayed on map for node
TARGET <rrd> N/A
USESCALE scalename n
MAXVALUE threshold N/A Uses Hobbit status by default
ICON filename y Except 'none','box','rbox','round'
USEICONSCALE N/A Uses Hobbit status by default
LABELOFFSET x y or x DIR n
LABELANGLE (0|90|180|270) n
LABELFONT ([1-5]) y Built-in fonts, and fonts defined with FONTDEFINE
COLOR n, use Hobbit status to set label background color
INFOURL url N/A Use Hobbit by default
OVERLIBGRAPH url N/A Use Hobbit by default
OVERLIBWIDTH x n
OVERLIBHEIGHT y n
OVERLIBCAPTION text N/A Use Hobbit/Devmon by default
NOTES text n
SET n
=head2 Link Options
LINK <linkname> y Link name, must be unique, does not appear anywhere
NODES y (no offset support) nodenames of nodes to link
TARGET y, but format is hobbit:testname:instancename hobbit:testname:instancename
e.g.: hobbit:if_load:Gi2/5 hobbit:if_load:Gi2/4
but hobbit: is optional, and test defaults to
if_load, so in many caes you can use:
TARGET Gi2/5 Gi2/6
USESCALE n

BANDWIDTH n (Uses Devmon's bandwidth calculation)
DUPLEX n (In future could support Devmon cdp test)
BWLABEL n
INBWFORMAT n

INCOMMENT n Uses Interface name for Devmon/if_load
OUTCOMMENT n Uses Interface name for Devmon/if_load
COMMENTFONT n

SPLITPOS x ([50]) n
COLOR n (Determined by Hobbit status color)
INFOURL n

OVERLIBGRAPH n Uses Hobbit based on TARGET value
