How to measure queueing time: from tomcat recieving request to axis web service

["Pim W." <p....@gmail.com>]

Hi,

I want to measure the queueing time starting from when Tomcat recieve the
request from a client until the request reach my process.
I am writing a web service application hosted under axis engine.
I want to
- Get the time stamp when the request arrive at Tomcat

And I then want to find the distance between the timestamp when Tomcat
recieves the request and the time stamp when my web service starts working.
But I dont know where or how should I modify tomcat to get the time stamp
when the request comes.
I tried to read the architecture of Tomcat but I dont really understand
where the request arrives.

I'm not sure if I should post this in user mailing list or developer mailing
list.
Can somebody please point me the way?

A Valve might be what you need - but you might need to hack the Connectors 
depending on how granular you need to be.

A Valve is just like a servlet filter.
