I have tomcat5. installed on a Windows 2003. Tomcat was installed as
part of a Custtomer application. Tomcat runs as a Windows service, and
one can see tomcat5.exe process in task manager. When I access the web
site of my third party application, I see thread count of tomcat5.exe
increase as well memory usage increase. I do not however see any jvm
(java)
process in task manager. When I look at vendor's script for setting up
windows service using tomcat5.exe, I do find references to java and
various jvm options such as minimum and maximum heap sizes.

I want to find find how much memory  on the heap is allocated as
people access the web site. I know in java console, I can set some
debugging/tracing parameters but they do not seem to take in effect
with tomcat service. Why?

Appreciate any pointers on where java process is for tomcat and how to
monitor its memory usage.

Thanks.
