The default configuration for Webalizer analyzes the default Apache logfile at 4:02 a.m. each day, as long as that logfile is not empty. The results can be read by using a browser on the same machine and accessing http://localhost/usage/ , which displays the report page. A sample report page is shown in Figure 7-30 .

7.12.1.1. Analyzing virtual host logfiles

This configuration assumes that your Apache virtual host logfiles are named /var/log/httpd/<virtualhostname>-<access_log> and are in combined format.

To configure Webalizer to analyze your virtual host logfiles each day, create the file /etc/cron.daily/00webalizer-vhosts :

#! /bin/bash
# update access statistics for virtual hosts
CONF=/etc/httpd/conf/httpd.conf
for NAME in $(sed -n 's=^[^#]*CustomLog logs/([^ ]*)-.*=1=p' $CONF)
do
 mkdir /var/www/usage/$NAME
 chmod a+rx /var/www/usage/$NAME
 LOG=/var/log/httpd/${NAME}-access_log
 if [ -s $NAME ]
 then
  exec /usr/bin/webalizer -Q -o /var/www/usage/$NAME $LOG
 fi
done

Make this file readable and executable by root :

# chmod u+rx /etc/cron.daily/00webalizer-vhosts

Next, edit /etc/webalizer.conf and place a pound-sign character ( # ) at the start of the HistoryName and IncrementalName lines to comment them out:

# HistoryName /var/lib/webalizer/webalizer.hist
...(Lines snipped)...
# IncrementalName /var/lib/webalizer/webalizer.current

This will ensure that a separate analysis history is maintained for each virtual host.

The virtual host logfiles will be analyzed every morning at 4:02 a.m., and the reports will be accessible at http://localhost/usage/<virtualhostname> .

7.12.1.2. Analyzing the FTP logfile

To analyze the vsftp logfile each day, create the file /etc/cron.daily/00webalizer-ftp :

#! /bin/bash
# update access statistics for ftp
if [ -s /var/log/xferlog ]; then
 exec /usr/bin/webalizer -Q -F ftp -o /var/www/usage/ftp /var/log/xferlog
fi

Make this file readable and executable by root :

# chmod u+rx /etc/cron.daily/00webalizer-ftp

Then create the directory /var/www/usage/ftp :

# mkdir /var/www/usage/ftp
# chmod a+r /var/www/usage/ftp

Make sure that you have made the changes to /etc/webalizer.conf noted previously.

Your FTP usage statistics will now be analyzed each day at 4:02 a.m. along with your web statistics. The reports will be accessible at http://localhost/usage/<ftp> .

7.12.1.3. Accessing the usage statistics from another location

It's often inconvenient to access the usage statistics from the same machine that is running Apache. To make the statistics password-protected and accessible from any system, edit the file /etc/httpd/conf.d/webalizer.conf to look like this:

#
# This configuration file maps the Webalizer log-analysis
# results (generated daily) into the URL space. By default
# these results are only accessible from the local host.
#
Alias /usage /var/www/usage
<Location /usage>
 Order deny,allow
 Allow from ALL
 AuthType Basic
 AuthName 'usage statistics'
