NAME

Parse::AccessLog - Parse Nginx/Apache access logs in "combined" format.

VERSION

Version 0.01

SYNOPSIS

Parses web server logs created by Apache/nginx in combined format. Assumes no knowledge of the server which creates the log entries.

Following the UNIX philosophy of "write programs that do one thing and do it well", this module does not attempt to validate any of the data/fields (e.g. match the IP address via a regex or some other method). This module assumes that the logs are already written by a web server daemon, and whether the data are "correct" or not is up to the end user. This module just parses it.

    use Parse::AccessLog;

    my $p = Parse::AccessLog->new;

    # returns one hashref
    my $log_line = q{127.0.0.1 - - [11/Jan/2013:17:31:36 -0600] "GET / HTTP/1.1" 200 612 "-" "HTTP-Tiny/0.022"};
    my $rec = $p->parse($log_line);

    ...

    # returns two hashrefs...
    my @log_lines = (
        q{127.0.0.1 - - [11/Jan/2013:17:31:36 -0600] "GET / HTTP/1.1" 200 612 "-" "HTTP-Tiny/0.022"},
        q{127.0.0.1 - - [11/Jan/2013:17:31:38 -0600] "GET / HTTP/1.1" 200 612 "-" "HTTP-Tiny/0.022"},
    );
    my @recs = $p->parse( @log_lines );

    ...

    # returns a hashref for each line in 'access.log'...
    my @recs = $p->parse( '/var/log/nginx/access.log' );

METHODS

new()

Constructor, creates a Parse::AccessLog parser object. Use of new() is optional, since the parse() method can be called as a class method also.

parse()

This is the only method (other than the constructor new()), and can be called as a class method or as an object method. It Does What You Want (probably).

Accepts a scalar or a list. If a scalar, can be either one line of an access log file, or can be the full path (absolute or relative) to an access log (e.g. /var/log/apache2/access.log). If a list, expects each element to be a line from an access log file. Will return either a single hashref or a list of hashrefs with the following keys:

    remote_addr
    remote_user
    time_local
    request
    status
    bytes_sent
    referer
    user_agent
