DESCRIPTION
-----------

GraphDefang is a configurable perl utility that parses arbitrary syslog 
entries and creates a set of configurable charts (png files) with the data.  
It is possible to output the png files to the filesystem or to a web browser
via a cgi.

The following attributes are definable:

	* Chart Type 	(stacked_bar or line)
	* Chart Time	(hourly, weekly, or monthly)
	* X-Axis	(Summary, Value1, Value2, Sender, Recipient, Subject,
			 or All)
	* Y-Axis	(any event logged with md_log within mimedefang-filter)
	* Top Number of Items to Display
	* Chart Title
	* Filter	
	* X and Y Graph Sizes
	* Graph Filename

Graphdefang will also cache summary data so that it is not necessary
to parse and recalculate old data each time new graphs are drawn.

You can see the output in action at:

INSTALLATION INSTRUCTIONS
-------------------------

1.  Install Required Perl Modules

2.  Untar the graphdefang distribution into a directory from where it can run.

3.  (for mimedefang only) Add md_log commands per the example mimedefang-filter
    (included with mimedefang-2.22+).

4.  Create a file, graphdefang-config, from the examples included with the
    distribution.  Set $DATAFILE and $OUTPUT_DIR in this file.

5.  Copy web/index.php to the $OUTPUT_DIR web directory.  Set $OUTPUT_DIR in 
    this file.

6.  Copy graphdefang.cgi to the $OUTPUT_DIR web directory.  Configure perl cgi
    access for this directory and set $GRAPHDEFANGDIR in this file.

7.  Run graphdefang.pl via cron.  I run mine every 15 mins.  You can also 
    run adhoc graphdefang queries against the DB by hitting graphdefang.cgi
    with a web browser.
