looking for memory profiler or dump analyzer for production use
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

That means ..
even when I start the monitoring component later
it will not work beyond the first hour after starting the jvm?

started in the free version. In the commercial version, the monitoring
information is availble the whole time - as for pricing - no idea..

Thanks!
Doesn't this mean that it is free:
"Freely Available! BEA JRockit is available for free download for evaluation and
production use."
i.e. that it can be used in production with no cost or licence fees?

Hi,
the one I know isn't free, but since you don't get many answers, try jrockit.
Jrockit is actually not a memory dump analyzer but a (high
performance) vm with extended monitoring support.
