Response time from Apache log

[napo]

My log format is below:
10.10.143.18 - "-" [21/Feb/2012:00:05:39 +0900] "POST /default/2881.ajax HTTP/1.1" 200 115538 "http://www.mycompany.com/index.jsp" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; InfoPath.1)"

I can see the clientip, refer fields but not response time after indexing. How can I get it and sort it on demand?

With Apache 2.4 the logging modul allows to activate New fields. One Field ist the prcocessing time. But the best is the New transaction id.

Yes,there is no response time field. It should be logged on web application server. Thanks
