J2EE Web Transaction Agent- response time

J2EE Web Transaction Agent- response time

Dear JAMon experts,

First of all, i have to say that your monitoring solutions is one of the greatest monitoring tools I found so far! The fine-granularity of monitoring at different levels is one of the key competitive advantages. 

I went  through the documentation and I was unable to precisely decide if it can server my requirements. You'd be able to quickly  help answering this need. 

My application architecture is (Load balancer + JBoss 3.2.3 + MySQL 5.0.19). I use J2sdk1.4.2.19 and my application uses Java servlets.

I want to log the processing for each request at the JBoss server as well as the the corresponding MySQL processing time of each request. I need to get these times separately. For example: 


If we have 3 requests; search for item, checkout, and login 

I want to log data such as the following: 

Request                JBoss P.T      MySQL P.T (*P.T.: Processing Time)
search for time         85 ms            150 ms
checkout                   50 ms            20 ms
login                        60 ms             80 ms       

I want to log such information for each request received by JBoss (along with request details- e.g., URL, request start and end time, response status, etc)

I found ( Monitor J2EE Web Transaction & J2EE Web Transaction Agent) to be useful for my case. However, I'have some inquiries:


Does the J2EE web transaction agent measure the queuing and thread allocation time for each request? 

Where does the collected measurement data are stored? Can I read the data from a log file instead of visually displaying it? I need all measurement data (not the statistics over period of time)

Can I only install and use the   J2EE Web Transaction Agent only to collect response time for each request?

Every how long measurement data is collected- per-request, every predefined period of time, or?


I look forward to hearing from you so I can proceed with the J2EE Web Transaction Agent if it suits my requirements

Thanks a lot
