I am in search of any tool through which i can measure quality of service of my sebservice which is being accessed through Apache .
My webservice is being deployed on tomcat and being accessed by Apache from outer  world.
The problem i am facing is My Customer uses apache's access logs to measure the quality of service by just seeing the error codes 200 (for OK) and rest others as NOK.

When my service raises any exception ex:object not found then its an OK case in regard to my quality of web service but apache shows code as 500 and they assume that my web service quality is bad.

is there any way through which we can print the response of web service in access logs in Apache.

I need this help urgently if anybody could do it pls....

With Regards
