beam-telemetry/telemetry

This system is a high-performance event telemetry library, originally written in Elixir but now implemented natively in Erlang. It provides mechanisms for attaching and detaching event handlers, emitting measurements, and managing span contexts. A key feature is the use of persistent term caching to optimize handler dispatch performance, supported by comprehensive test suites validating core telemetry behaviors.

beam-telemetry/telemetry was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point the surveyor at a repository you know and see whether you agree with it.
