是否可以在堆转储中查看来自hprof dump / threads的线程

问题描述

我有一个大的（5GB）hprof转储，当发生 OutOfMemoryError 时由应用程序创建。 （使用

I have got a large (5GB) hprof dump, created by application when OutOfMemoryError occurred. (Using XX: HeapDumpOnOutOfMemoryError ).

Unfortunately there are no logs collected when this error happened. Re-creating this will take couple of hours. I was hoping if some tools could show the exception stack trace or all threads stacks etc from hprof.

I am currently using MAT, could not see a way to get thread information. Which tool I could use?

(I am not sure if hprof file has information about thread/location of call when OOM occurred).

( I do know to how to take thread dump in normal cases. The trouble here is the event already happened, all I have is the hprof dump. )

解决方案

MAT can show the threads directly now (perhaps this was added since the question was asked).
