feature request:relationship of objects on Java Heap about jvm-tools HOT 6 OPEN

Could you elaborate your request? Is it about heap dump parser library?

from jvm-tools.

The feature is something like Eclipse Memory Analyzer(https://www.eclipse.org/mat/about/screenshots.php).
The hh（or jmap -histo）is just like this feature in Eclipse MAT:

memory leak is not easy to debug according this picuture. But feature "Dominator Tree" and "Path to GC Roots" could help much to do this work:

Eclipse MAT is offline, so sometimes it is not very convenient. And JProfiler has similar feautre and it is online, but it is commercial and GUI interface.
So a online analyzer, CUI interface and open source implementation is very great.

+1 for a CLI tool
ability to do both offline and online would be awesome.

I got the idea.

I working on CLI analyzer for heap dump files (offline version).

Concerning online, JProfiler probably exploits JVMTI to make it work. JVMTI would require non trivial C++ coding which I would like to avoid for number of reasons. I have few ideas how similar functionality can be implemented in pure Java, but I can promise to start work on this anytime soon.

You are a great man !

Oops. There was a typo, it should be "I can not promise to start work on this anytime soon". I'm sorry to disappoint you.
But do not loose hope :)
