WindowsStorageServer2012+IIS+AWStatsでログを収集しようとしています。

ログの解析をすると

c:\Program Files (x86)\AWStats\wwwroot\cgi-bin>awredir.pl -config=awstats.conf -
update
----- awredir 1.2 (build 1.12) (c) Laurent Destailleur -----
This script is absolutely not required to use AWStats.
It's a third tool that can help webmaster in their tracking tasks but is
not used by AWStats engine.

This tools must be used as a CGI script. When called as a CGI, it returns to
browser a redirector to tell it to show the page provided in 'url' parameter.
So, to use this script, you must replace HTML code for external links onto your
HTML pages from
<a href="http://externalsite/pagelinked">Link</a>
to
<a href="http://mysite/cgi-bin/awredir.pl?key=ABCDEFGH&url=http://externalsite/p
agelinked">Link</a>

For your web visitor, there is no difference. However this allow you to track
clicks done on links onto your web pages that point to external web sites,
because an entry will be seen in your own server log, to awredir.pl script
with url parameter, even if link was pointing to another external web server.

設定の何を変えれば解析が出来るようになるのでしょうか？
宜しくお願いいたします。
