Starting 'jhat' Web Server on a Heap Dump File

一、如何使用 jhat

In an earlier tutorial example, I created a Java heap dump file with the "jmap" tool on my GarbageCollection.java program. The heap dump file is named as GarbageCollection.map. Now I want to try to run the "jhat" Web server on this dump file and browse the heap dump with a Web browser.

1. Run the "jhat" command with default options:

C:\herong>\Progra~1\java\jdk1.8.0\bin\jhat GarbageCollection.map

Reading from GarbageCollection.map...
Dump file created Jan 1 00:08:10 EDT 2008
Snapshot read, resolving...
Resolving 67324 objects...
Chasing references, expect 13 dots.............
Eliminating duplicate references.............
Snapshot resolved.
Started HTTP server on port 7000
Server is ready.

2. Run a Web browser with http://localhost:7000. The "jhat" heap dump file server page shows up: 

See next sections on how to use "jhat" Web server to browse heap objects.

二、UNIX 系统怎么浏览器浏览呢

Started HTTP server on port 7000

有一个办法就是利用SecureCRT的Port forwording 端口转发功能。

将本地的地址转发到服务器端的7000端口
