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
