.SH NAME
w3c_extended2dlf \- convert W3C Extended Log file as used by MS IIS to DLF
.SH SYNOPSIS
.IX Header "SYNOPSIS"
\&\fBw3c_extended2dlf\fR \fIfile\fR
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBw3c_extended2dlf\fR 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
.PP
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.
.PP
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/.
.PP
To have the maximum information in you reports, we suggests that you log
the following fields :
.PP
.Vb 2
\& date, time, c\-ip, c\-dns, cs\-uri, cs\-method, sc\-bytes, sc\-status,
\& cs(User\-Agent), cs(Referer) and cs\-username
.Ve
.PP
We also support the cs\-uri\-stem field.
.PP
Other fields will be ignored.
.SH LIMITATIONS
.IX Header "LIMITATIONS"
The converter doesn\*(Aqt handle aggregation (record with count field) and
will refuse to process those logs. Also it doesn\*(Aqt support changing
the fields in the middle of the log file. It will ignore records that
don\*(Aqt have the same schema than the first one defined.
.SH EXAMPLES
.IX Header "EXAMPLES"
To process a log as produced in the W3C Extended Log Format:
.PP
.Vb 1
\& $ w3c_extended2dlf < extended.log
.Ve
.PP
w3c_extended2dlf will be rarely used on its own, but is more likely
called by lr_log2report:
.PP
.Vb 1
\& $ lr_log2report w3c_extended < /var/log/httpd/extended.log
.Ve
