How can I analyze a heap dump in IntelliJ? (memory leak)

Question

I have generated a heap dump from my java application which has been running for some days with the jmap tool -> this results in a large binary heap dump file.

Answer 1

VisualVM plugin for Intellij Idea

Answer 2

The best thing out there is Memory Analyzer (MAT), IntelliJ does not have any bundled heap dump analyzer.

Answer 3

You can just run "Java VisualVM" which is located at jdk/bin/jvisualvm.exe

This will open a GUI, use the "File" menu -> "Load..." then choose your *.hprof file

That's it, you're done!

Answer 4

There also exists a 'JVM Debugger Memory View' found in the plugin repository, which could be useful.

Answer 5

You can also use VisualVM Launcher to launch VisualVM from within IDEA. https://plugins.jetbrains.com/plugin/7115?pr=idea I personally find this more convenient.

Answer 6

You can install the JVisualVM plugin from here: https://plugins.jetbrains.com/plugin/3749?pr=

This will allow you to analyse the dump within the plugin.
