# jhat

> Java Heap Analysis Tool.

- Analyze a heap dump (from jmap), view via http on port 7000:

`jhat {{dump_file.bin}}`

- Analyze a heap dump, specifying an alternate port for the http server:

`jhat -p {{port}} {{dump_file.bin}}`

- Analyze a dump letting jhat use up to 8GB RAM (2-4x dump size recommended):

`jhat -J-mx8G {{dump_file.bin}}`
