# apache-access\_log2dlf(1)

convert apache access logs to dlf format

## NAME

apache-access\_log2dlf - convert apache access logs to dlf format

## SYNOPSIS

**apache-access\_log2dlf** *combined***⎪***common***⎪***referer*

## DESCRIPTION

This script reads apache logfile, in several formats. Supported formats as defined in e.g. apache's httpd.conf are: "combined", "common" and "referer".

"common" is used to parse the Common Logfile Format that several WWW servers use.  It is documented on http://www.w3.org/Daemon/User/Config/Logging.html#common-logfile-format.

"combined" is defined in httpd.conf as:

```
 LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
   \"%{User-Agent}i\"" combined
```

This generates lines in the logfile like e.g.

```
 gelfand.mdcc.cx - - [31/Jul/2000:22:01:13 +0200] "GET
   /~vanbaal/poetry.html HTTP/1.0" 200 2554
   "http://mdcc.cx/~vanbaal/" "w3m/0.1.9"
```

The logs are converted to the DLF format:

```
 gelfand.mdcc.cx mdcc.cx - 200 3138 GET /howto.html html
   /howto.html HTTP/1.0HTTP/1.0 31/Jul/200022:08:12
```

On apache servers, running various virtual servers, logs like

```
 1.2.6.241 3.4.3.21 - - [13/Oct/2000:10:57:13 +0200]
   "GET / HTTP/1.0" 200 250
```

are frequently seen. This are 'common' logs, with an added first field which  indicates the virtual server being visited. A quick and dirty trick to handle these logs is doing:

```
 (while read virt rest; do echo $rest >> common.log-$virt; \
   done) < common.log
```

Since boa ( http://www.boa.org/ ) access logs are in exactly the same format  as apache combined logs, this script can be used to process these too.
