NAME¶
w3c_extended2dlf - convert W3C Extended Log file as used by MS IIS to DLF
SYNOPSIS¶
w3c_extended2dlf file
DESCRIPTION¶
w3c_extended2dlf converts web server log files in the W3C Extended Log
Format to the www DLF. This log format is defined at
http://www.w3.org/TR/WD-logfile.html
It is used by IIS 4.0 and IIS 5.0. This is a customizable format which contains
an header specifying which information is present in the log.
Some documenation on these log file formats is available in the section on
"Analyzing Log Files (IIS 6.0)" in the "IIS 6.0
Documentation" at the "Microsoft Windows Server 2003
TechCenter" at
http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/
Library/IIS/610b7d2c-90d6-4e40-be79-aaf88a283f03.mspx?mfr=true . The newer IIS
7.0 product is documented at
http://www.iis.net/.
To have the maximum information in you reports, we suggests that you log the
following fields :
date, time, c-ip, c-dns, cs-uri, cs-method, sc-bytes, sc-status,
cs(User-Agent), cs(Referer) and cs-username
We also support the cs-uri-stem field.
Other fields will be ignored.
LIMITATIONS¶
The converter doesn't handle aggregation (record with count field) and will
refuse to process those logs. Also it doesn't support changing the fields in
the middle of the log file. It will ignore records that don't have the same
schema than the first one defined.
EXAMPLES¶
To process a log as produced in the W3C Extended Log Format:
$ w3c_extended2dlf < extended.log
w3c_extended2dlf will be rarely used on its own, but is more likely called by
lr_log2report:
$ lr_log2report w3c_extended < /var/log/httpd/extended.log
