nm - nanometer

Collect metrics about observed events with low collection overhead even in highly multithreaded applications running on 100+ processors.

Collected metrics

For each defined event, the following metrics are collected:

• Count of observations (u64).
• Mean magnitude of observations (i64).
• (Optional) Histogram of magnitudes, with configurable bucket boundaries (i64).

More details in the crate documentation.

This is part of the Folo project that provides mechanisms for high-performance hardware-aware programming in Rust.
