How to monitor response time on WDA

Hi, all

I have done lots of readings and come up empty so far. We are trying to monitor the response time of the webdynpro for ABAP programs. In the classic ST03N, only the abap reports(se38/se37) are reported. The WDA are not reported properly ... or I haven't found a way to display it. Is there another way to monitor WDA response time? I am aware of the WD_TRACE_TOOL and STAD. But they don't give me performance breakdown on frontend and db response time in a historical fashion.

Please advise.

Thanks,

Jonathan.

PS. I am not sure if this is the right forum. I tried to post it in the WDA forum but the moderator never releases my post for whatever reason.
