# NAME
#
#	aWebVisit Version 0.1.6b, 18/02/1999
#
# AUTHOR
#
#	Michel Dalle (michel.dalle@usa.net), Copyright 1999.
#
# DISTRIBUTION
#
#	http://gallery.uunet.be/Michel.Dalle/awv.html
#
#	If you like this software, or if you make modifications that might
#	be of interest to other people (new statistics, optimisations, ...),
#	please send me an e-mail !
#
#	This software is made available AS IS, and is distributed without
#	warranty of any kind, either expressed or implied.
#
# PURPOSE
#
#	Reads the Web server logfile(s) and extracts visitor information
#	like :
#		- the most commonly used ENTRY, TRANSIT, EXIT and HIT & RUN
#		  pages of your website
#		- the most frequently followed INCOMING, INTERNAL, OUTGOING
#		  and IN & OUT links of your website
#		- the average DURATION of each visit
#		- the average number of PAGES viewed PER VISIT
#		- the average TIME SPENT on each page
#		- the path of the LONGEST VISIT (in time and/or hits)
#		- ...
#
#	The visitor information is stored in HTML pages in a directory
#	of your choice (see configuration below).
#
#	A companion program called aWebVisit-Map allows you to click on a
#	page and follow all the links to and from that page (CGI).
#
# REMARKS AND LIMITATIONS
#
#	This script does not intend to provide "standard" web statistics like
#	the number of hits per day, the status codes, the distribution per
#	domain, etc. There are more than enough programs available for that !
#
#	The script accepts logfiles in the Common Log Format (CLF) or NCSA
#	Combined format. Other formats can be used if you modify the
#	appropriate fields in the script below.
#
#	Images (URLs of type .gif or .jpg) are normally ignored, except as
#	being part of an on-going visit. URLs with anchor points
#	(http://...#..) are treated as separate pages, but URLs with
#	parameters (http://...?..) are treated as a single page.
#
#	This script is not useful for sites having only a few "hits" per
#	day, since there must be a sufficient number of visits to extract
#	significant statistics. You might as well directly read the logfile.
#
#	It is also not intended for sites having millions of hits per day
#	or millions of pages on their website(s), since reading the logfiles
#	and generating the statistics can take some time (e.g. for a logfile
#	of 65 MB, aWebVisit takes about 11 minutes on a PC). There may be some
#	more professional packages supporting this type of websites.
#
#	Note that clients behind proxy servers cannot be differentiated based
#	on a web server logfile (unless you use authentication). This is not
#	a bad limitation if the number of log entries is sufficiently large.
#
#	You can change all this in the script below (and send me a mail).
#
# EXAMPLES OF USE
#
#	awebvisit logfile
#	perl awebvisit logfile
#	awebvisit logfile.*Jan*
#	grep that_client logfile | awebvisit
#
# HISTORY
#
#	0.1.6b 18/02/99	Minor bug fix for exclude_visit and include_visit
#
#	0.1.6 17/02/99	+Companion program aWebVisit-Map to travel through the
#			 pages and see the links to and from each page (CGI) !
#			+Modified contents of statistics file for aWebVisit-Map
#			+Configurable removal and/or replacement of some parts
#			 of URLs (parameters, anchor points, long paths, ...)
#			+Configurable exclusion/inclusion of visit entry-points
#			 (e.g. robots should start with '/robots.txt')
#			+Configurable exclusion/inclusion of hosts (networks,
#			 domains, ...)
#			+Configurable exclusion/inclusion of URLs
#
#	0.1.5 07/02/99	+Create graphical maps of entries, exits and transits
#			+Support visits that cross midnight (assuming days
#			 follow each other without gaps in the logfiles)
#			+Review table outputs
#			+Drastically reduce memory requirements for big files
#
#	0.1.4 31/01/99	+Separate links into incoming, internal, outgoing and
#			 in&out links
#			+Add status information
#			+Add 1st level flow map
#			+Rewrite statistics code
#			+First try at entry and exit trees
#
#	0.1.3 24/01/99	+Separate hit & runs from entry and exit points
#			+Add transit points
#			+Add rank percentages
#
#	0.1.2 23/01/99	+Add least used entry and exit points
#			+Streamline table outputs
#			+Add some explanations
#
#	0.1.1 20/01/99	Generate HTML output
#
#	0.1.0 18/01/99	First public version
#
# FUTURE
#
#	This is probably as far as it goes, unless you send your suggestions
#	and wishes to (michel.dalle@usa.net)...
#
#	E.g. take into account status code changes during a visit.

#
# CONFIGURATION FOR aWebVisit
#
# The configuration is divided into 5 sections :
#
#	1. Global Settings
#	2. Layout Definition
#	3. Logfile Analysis
#	4. Data Export
#	5. Web Map Configuration
#
# Hint:	you can start by checking 1.a., 5.a. and 5.b. now, and then try
#	changing the other ones later on.
#	Option 3.a. is an interesting one too : it determines which URL types
#	to exclude or include (images, RealAudio, style-sheets, java, ...).
#

#==========================================================================
#
# 1. Global Settings
#
#==========================================================================

#=======
# 1.a.	Output directory for the aWebVisit reports
#	- change this to a directory containing your HTML documents, or some
#	specific sub-directory.
#=======

$outdir = ".";
#$outdir = "../docs";
#$outdir = "../docs/awv";

#=======
# 1.b.	Output filenames
#	The script generates output files with the following names :
#	<name>f.html <name>i.html <name>s.html <name>1.html <name>2.html...
#	- change this if these names already appear in the output directory.
#=======

$name = "awebvisit";
#$name = "awv_";

# Hint:	if you intend to place the aWebVisit reports in a separate directory,
#	copy <name>f.html to index.html (or whatever your default page is)
#	after running awebvisit. That makes it easier to get to the reports
#	from your browser... (on Unix, you could also create a soft link)

#=======
# 1.c.	Visit timeout (in seconds)
#	- change this if you want to allow a different "sleeping time"
#	(Some people use 30 minutes, others use 5 minutes)
#=======

$timeout = 450;
#$timeout = 600;

#==========================================================================
#
# 2. Layout Definition
#
#==========================================================================

#=======
# 2.a.	HTML Background Color
#	- change this to your favorite background color
#=======

$bgcolor = "#FFEEDD";
#$bgcolor = "#A0E0FF";

#=======
# 2.b.	Background Color for highlighted columns in tables
#	- change this to your favorite highlight color
#=======

$highcolor = "#CCFFCC";
#$highcolor = "#FFEEDD";

#=======
# 2.c.	Display Top N pages only
#	- change this if you want to see more pages in each table
#=======

$toppages = 20;
#$toppages = 30;

#=======
# 2.d.	Display Top N links only
#	- change this if you want to see more links in each table
#=======

$toplinks = 100;
#$toplinks = 120;

#==========================================================================
#
# 3. Logfile Analysis
#
#==========================================================================

#//////////////////////////////////////////////////////////////////////////
# Introduction to regular expressions (used for pattern matching below)
#
# '|' means a logical OR.
# '(' and ')' can enclose different OR choices
# '^' means the start of the string (URL, host, ...)
# '$' means the end of the string (URL, host, ...)
# '\' is used before any character that is not alphanumeric : '\.', '\/', '\?'
#//////////////////////////////////////////////////////////////////////////

#=======
# 3.a.	Exclude 'images' / include 'pages', i.e. URLs matching the following
#	pattern
#	- change this if you want to exclude other URLs (e.g. java, testpages)
#
#	NOTE : this replaces variable '$exclude' of aWebVisit 0.1.5 !!
#=======

$exclude_url = '\.(gif|jpg)$';
#$exclude_url = '';

# Example - exclude .gif, .jpg, .css and .js pages, and all URLs starting with
# /test or located under /stats/awv/
#
#$exclude_url = '\.(gif|jpg|css|js)$|^\/(test|stats\/awv\/)';

# Or:	If you only want to INCLUDE certain URLs, leave the $exclude_url blank
#	and use the $include_url below :

$include_url = '';
#$include_url = '\.(htm|html)$';

#=======
# 3.b.	Exclude/include visits from specific hosts, e.g. from your own system
#	- leave blank if you don't want to exclude any hosts
#=======

$exclude_host = '';

# Example - remove host 127.0.0.1, all hosts from network 150.93.* and from
# domain *.abc.com (this only works if your logfile contains domain names) :
#
#$exclude_host = '^127\.0\.0\.1$|^150\.93\.|\.abc\.com$';

# Hint:	it is actually faster to remove all undesired hosts from the logfiles
#	BEFORE aWebVisit analyses them. On Unix, use something like :
#	grep -v "exclude_me.com" <logfile(s)> | awebvisit

# Or:	if you only want to INCLUDE certain hosts, leave the $exclude_host
#	blank and use the $include_host below :

$include_host = '';
#$include_host = '^150\.93\.|\.abc\.com$';

# Hint:	it is actually faster to select all desired hosts from the logfiles
#	BEFORE aWebVisit analyses them. On Unix, use something like :
#	grep "include_me.com" <logfile(s)> | awebvisit

#=======
# 3.c.	Exclude/include visits with an entry point that matches this pattern
#	Typically used for excluding visits from 'clean' robots, i.e.
#	those starting with asking for '/robots.txt'.
#	- leave blank if you don't mind including robot visits, or replace
#	if you want to exclude visits starting at a certain page...
#=======

$exclude_visit = '^\/robots.txt$';
#$exclude_visit = '';

# Or:	if you only want to INCLUDE certain entry points, leave the
#	$exclude_visit blank and use the $include_visit below :

$include_visit = '';
#$include_visit = '^\/spanish\/index.html$';

#=======
# 3.d.	Remove whatever matches the following pattern from each URL
#	- change this if you want to exclude anchor points, include some
#	CGI parameters, remove some irrelevant parts from long URLs, ...
#=======

# this removes all parameters from URLs (http://...?.. --> http://...)
$remove_from_url = '\?.*$';
#$remove_from_url = '';

# Example : remove anchor points, remove all CGI parameters except for the
# first one (before the first '&'), or remove '/a_long/useless/path' from
# each URL (whatever matches first is done, the rest is ignored !)
#
#$remove_from_url = '#.*$|&.*$|\/a_long\/useless\/path';

#=======
# 3.e.	Replace whatever matches the first pattern with the second one
#	for each URL - typically used to replace '.../' with '.../index.html'
#	(or whatever your default page is)
#	- leave blank if no replacements are required
#=======


%replace_url = (
#format:'replace' 	=> 'with',
#	'\/$'		=> '\/index.html',
#	'^\/this_very_long_dir\/'	=> '\/that\/',
);

# Hint:	don't try to replace too many URLs, since this may take some time...
#	It may be better to replace the URLs in the logfiles BEFORE aWebVisit
#	analyses them.

#==========================================================================
#
# 4. Data Export
#
#==========================================================================

#=======
# 4.a.	Export data to file (in delimited format) - leave blank otherwise
#	- save the data of all URLs and links in delimited format
#=======

$csvfile = $name . ".data";
#$csvfile = '';

#=======
# 4.b.	Export statistics to file - leave blank otherwise
#	- save the aWebVisit statistics for aWebVisit-Map
#=======

$statfile = $name . ".stat";
#$statfile = '';

# Hint:	make sure aWebVisit-Map uses the same statistics file !

#=======
# 4.c.	Delimiter for data and statistics file - usually a tab is safest
#	- change if your analysing tool and/or DB cannot use this deliminer
#=======

$delim = "\t";
#$delim = "|";

# Hint:	make sure aWebVisit-Map uses the same delimiter !

#==========================================================================
#
# 5. Web Map Configuration
#
#==========================================================================

#=======
# 5.a.	Location of the FLY program for graphics - leave blank if not there
#	You can get pre-compiled binaries for Windows 95 & NT, various UNIXes,
#	and other platforms at http://www.unimelb.edu.au/fly/
#=======

$flyprog = './fly';
#$flyprog = '/usr/local/bin/fly';
#$flyprog = 'd:\\perl\\fly-1.6.0\\fly.exe';

#=======
# 5.b.	Exact URL of the aWebVisit-Map CGI - leave blank if not installed
#	(but you should !)
#=======

$cgiprog = '';
#$cgiprog = '/cgi-bin/awv-map.cgi';

#=======
# 5.c.	Number of entry pages to be shown in the web maps
#	- better try it out before changing this
#=======

$topentries = 7;
#$topentries = 10;

#=======
# 5.d.	Number of transit pages to be shown in the web maps
#	- better try it out before changing this
#=======

$toptransits = 12;
#$toptransits = 15;

#=======
# 5.e.	Number of exit pages to be shown in the web maps
#	- better try it out before changing this
#=======

$topexits = 7;
#$topexits = 10;
