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.
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
