See through the erlang VM with ease

I meant, an implementation which can give runtime memory consumption of erlang functions.

The current implementation would grab all the function calls and their corresponding memory at every call and return.

Limitations

• Batch processing while writing to the file, if stopped in middle last batch messages would be lost.
• Recursive looping is not automatically prevented, need to take care while tracing OTP modules.

Good things

• OTP calls are by default isolated, and their tracing should be set explicitly.
• Used xref for validation and event manager for seamless message processing.
• Trace file consumption which is supposed to be in millions, happens now in "rust programming language" for performance reasons.

Roadmap

Still need to work hard on

• function call visualization for a single process with flamegraph(In Progress)
• visualizing concurrent processes
• memory consumption without loosing the essence.(Started to think)
