Hello,
I am looking for a (free) memory dump analyzer which is capable for being used
in production on tomcat 5.5 @ w2k server.
That means it should not have a performance impact in every day operation,
but should be able to generate memory dumps on request, which could be analyzed
offline.
I have tried HAT but it failed, showing errors on loading the created heap
files.
Then I found ariadna (http://mernst.org/ariadna/) which "has an almost zero
overhead agent".
But it shows not much information. So I have tried extending ariadna.
(See this screenshot:
http://home.arcor.de/javadeveloper/ariadnaXT/instance_from_tomcat.png)
But there are unresolved issues/bugs. I wonder if there is not another tool,
which can be used every day.
Does anyone know about an memory (dump) analyzer,
which can be used on a tomcat production instance (W2K), i.e. with almost zero
overhead?
Karl-Heinz
