Hi,
Is it possible to find out the per deployed context heap usage in
tomcat?
With a profiler you can look at the retained size of the web
application class loader instance associated with a web application.
I don't think this will tell you the volume of objects which belong to
those classes, though.
If I read a big String into my application, it won't be counted
towards the retained size of the web application classloader -- or
will it? I don't understand how that String object could count towards
the classloader's memory footprint.
It should do. The profiler traces obejct references and they should all
lead back to the web application class loader.
What reference path would lead from a java.lang.String object to the web
application ClassLoader? It's allocation-path? That would be tied to the
Thread which allocated it, not to the TCCL the Thread happened to have
at the time.
I've never tried to do this before and I suspect you have, so I'm not
trying to say "you're wrong" -- because I know better ;) -- but I'd like
to understand what exactly I'm missing, here.
