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 8 GB RAM (2-4x dump size recommended):
jhat -J-mx8G {dump_file.bin}
