Response Time in Tomcat
Hi,
I am monitoring Tomcat 6 Performance and I want to get the Response Time
of the incoming Request. And I would like to know what the differents
between requestProcessingTime and processingTime, and also I would like
to know the unit of these attributes. And the other problem I noticed
that when the request is finished through jmxproxy the thread that
process that request is still alive...that's normal?
Thanks in advance..

Yes its the Sum, it holds a vector of all the active requests
But I dont know what that actually means... because I think threads will
hang around until recycled, and a total is actually meaningless.
Might be adding something that was used once ages ago???
Maybe that is useful, but not really for load testing???
Useful possibly only to a TC developer... for a normal mortal like me, its
just a number ;)

you mean average Total Processing as a average time, right? but if I
want to know all RequestProcessor? I have to get the processingTime of
GlobalRequestProcessor?

This stuff (JMX) is nice and interesting, but I'm not sure if its the right
tool to actually test performance
Have a little look at Jmeter... with that you can whack TC and really see
how its holding up.
Or possibly watch the JMX while you whack it... its more fun ;)
