Memtrace viewer

OCaml now has runtime support for statistical memory profiling. Given a set of callbacks and a sampling rate it will run these callbacks on a sample of all allocations done by an OCaml program.

Unlike the spacetime memory profiler, this support aims to have low enough overhead to use in production and does not require any special compilation options.

Memtrace is a library built on top of this support, which generates compact traces of a program's memory use.

The Memtrace Viewer provides a web UI for exploring a trace produced with the Memtrace library.
