dtrace discuss - Sep 2009 - Dtrace and java 1.5

Hi,

I have used dtrace in the past for diagnosing IO/filesystem related issues.
So I am a bit familiar with dtrace scripts

Now I want to diagnose performance problems in the java area.
May be memory leak etc. 
The hotspot provider is not present.
How can I get them? 

Does someone have any further advice?

regards Hans

BTW I tried to understand the info on several websites but it has not become
clear to me how to get the dvm or djvm providers.

In that post you can find links to the agent plugins.

You may also find my JavaONE hands on lab useful.
http://developers.sun.com/learning/javaoneonline/j1lab.jsp?lab=LAB-9400&yr=2008&track=1

It talks about using DTrace for Java 1.4.2, 1.5, 6.0 and 7. You can  
also see how to use it for other scripting languages, mysql and C  
applications. Its meant to be a step by step guide.
