NAME

       common2dlf - convert Common Log Format web server log files to www DLF

SYNOPSIS

       common2dlf file

DESCRIPTION

       common2dlf converts Common Log Format web server log files to the www DLF. Common Log
       Format is a standard log format that was originally implemented in the CERN httpd web
       server but that now supported nowadays by most web servers. Apache, IIS, Boa and PureFTPD
       can be configured to log in that format.

       If the file argument is missing, STDIN will get parsed.  DLF will be printed on STDOUT.

COMMON LOG FORMAT

       The Common Log Format has the following format:

       remotehost rfc931 authuser [date] "request" status bytes

       where the fields have the following meaning:

       remotehost
           The host that made the request. Can be an IP or a hostname.

       rfc931
           The result of an ident lookup on the host. This is usually never used.

       authuser
           The authenticated username.

       date
           The timestamp of the request.

       request
           The first line of the request. Usually in the format "method request-uri http-
           version".

           See also RFC 2616, section 5.1.

       status
           The result status of the request. i.e. 200, 301, 404, 500.

       bytes
           The size of the request sent to the client.

       Log example:

         127.0.01 - - [11/03/2001 12:12:01 -0400] "GET / HTTP/1.0" 200 513
         dsl1.myprovider.com - francis [11/03/2001 12:14:01 -0400] "GET /secret/ HTTP/1.0" 200 1256

EXAMPLES

       To process a log as produced in the common logformat:

        $ lr_run common2dlf < common.log

       common2dlf will be rarely used on its own, but is more likely called by lr_log2report:

        $ lr_log2report common < /var/log/httpd/common.log
