Ruby heap analyzer
Clone the repo.
bin/memory_analyzer /path/to/heap.json
This will parse the file and drop you into an IRB session
Parsing: |======================================================| Time: 00:00:03

From this point you have access to the heap in a variable called $heap
upon
which you can call helper methods.
