Request Logging in Tomcat 6

Hi,


I've been working with performance measurements of web services and I've
faced this problem. For each request to my system (running in a tomcat 6) I
need to log these information:


Received Bytes (request content length)
Served Bytes (response content length)
Response Time (the time taken by the server to process the request)

 
 CPU Time (optional)
 
 I/O Time (optional)

URI
Cookies(the value of some specific cookies)
Request Content Data




I found something about Tomcat Access Log Valve (
http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html
http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html ) but this valve
do not offer enough information for me.


Somebody can help me ?

Actually, the latter two are simple:

Thank you a lot Kees,

  acctually I'm checking 2 possible implementations out. These two options
seems to be good.
  1- to use Servlet Filters
  2- to extend a AccessLogValve

  Regarding CPU time I have searched deep in the link you have passed me and
I found something about 
http://www.javaworld.com/javaworld/javatips/jw-javatip92.html?page=1 JVMPI 
(JVM Profiler Interface). It seems to offer a way to obtain such information

  So, thanks again

Best Regards

If you need this much detail, best write your own servlet filter and  
log it yourself.

CPU and I/O times are tricky. If you get that to work, let me know. :-)
