Memory Analysis & Garbage Collection Tuning
Diagnose memory growth, inspect per-process heaps, and tune Erlang garbage collection to keep long-running nodes healthy.
Why Memory Matters
Erlang nodes can run for months. A small per-process leak or unbounded mailbox grows silently until the node is killed by the OS. Observability into memory is essential.
System-Wide Memory
erlang:memory/0 returns a breakdown: total, processes, atom, binary, ETS and more. Watch the categories that grow over time.
