Log File Analyzing

Hello,

I user the following in my vhosts.conf file to rotate my logs as they were becoming unmanageably large:

LogFormat "%h %a %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" log_this
CustomLog "|/usr/local/apache/bin/rotatelogs /home/users/intersharedev/logs/access_log 2593000" log_this env=!dont_log

And this has resulted in log entries which look like:

194.128.255.225 194.128.255.225 [04/Feb/2002:15:07:42 +0000] "GET /bestpractices/index.php HTTP/1.1" 200 15450 "http://www.casewise.
co.uk/lounges/index.php" "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)"

As you can see the IP address is being inserted twice. How can I get rid of this?

Also I use webtrends to analyze logfiles, however it doesn't recognise this format, I hope that it will recognise the format as long as the IP address is only there once, however I'm not sure. Has anyone any suggestions what I can do going forward, and also how I can analyze my previous logs in the above format?

Thanks very much.

Remove %h or enable HostnameLookups or perform post DNS lookup.
