NAME
    Apache::DBILogger - Tracks what's being transferred in a DBI
    database

SYNOPSIS
      # Place this in your Apache's httpd.conf file
      PerlLogHandler Apache::DBILogger

      PerlSetVar DBILogger_data_source    DBI:mysql:httpdlog
      PerlSetVar DBILogger_username       httpduser
      PerlSetVar DBILogger_password       secret
      
    Create a database with a table named B<requests> like this:

    CREATE TABLE requests ( id mediumint(9) DEFAULT '0' NOT NULL
    auto_increment, server varchar(127) DEFAULT '' NOT NULL, bytes
    mediumint(9) DEFAULT '0' NOT NULL, user varchar(15), filename
    varchar(200), remotehost varchar(150), remoteip varchar(15)
    DEFAULT '' NOT NULL, status smallint(6) DEFAULT '0' NOT NULL,
    timeserved datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,
    urlpath varchar(200) DEFAULT '' NOT NULL, referer varchar(250),
    useragent varchar(250), PRIMARY KEY (id), KEY server_idx
    (server) );

    Its recommended that you include

    use Apache::DBI; use DBI; use Apache::DBILogger;

    in your startup.pl script. Please read the Apache::DBI
    documentation for further information.

DESCRIPTION
    This module tracks what's being transfered by the Apache web
    server in a SQL database (everything with a DBI/DBD driver).
    This allows to get statistics (of almost everything) without
    having to parse the log files (like the Apache::Traffic module,
    just in a "real" database, and with a lot more logged
    information).

    After installation, follow the instructions in the synopsis and
    restart the server. The statistics are then available in the
    database. See the section VIEWING STATISTICS for more details.

PREREQUISITES
    You need to have compiled mod_perl with the LogHandler hook in
    order to use this module. Additionally, the following modules
    are required:

            o DBI
            o Date::Format

INSTALLATION
    To install this module, move into the directory where this file
    is located and type the following:

            perl Makefile.PL
            make
            make test
            make install

    This will install the module into the Perl library directory.

    Once installed, you will need to modify your web server's
    configuration file so it knows to use Apache::DBILogger during
    the logging phase.

VIEWING STATISTICS
    I haven't made any pretty scripts og web interfaces to the log-
    database yet, so you're on your own. :-)

    For a start try:

    hit count and total bytes transfered from the virtual server www.company.com
        `select count(id),sum(bytes) from requests where
        server="www.company.com"'

    hit count and total bytes from all servers, ordered by number of hits
     
    `select server,count(id) as hits,sum(bytes) from requests group by server order by hits desc'
    count of hits from macintosh users
        `select count(id) from requests where useragent like
        "%Mac%"'

    hits and total bytes in the last 30 days
        `select count(id),sum(bytes) from requests where
        server="www.company.com" and TO_DAYS(NOW()) -
        TO_DAYS(timeserved) <= 30'

    hits and total bytes from www.company.com on mondays.
        `select count(id),sum(bytes) from requests where
        server="www.company.com" and dayofweek(timeserved) = 2'

    See your sql server documentation of more examples. I'm a happy
    mySQL user, so I would continue on

SUPPORT
    This module is supported via the mod_perl mailinglist
    (modperl@listproc.itribe.net).

    I would like to know which databases this module have been
    tested on, so please mail me if you try it.
