foam-otel

https://github.com/foam-ai/packages

A thin, safe wrapper over the official OpenTelemetry libraries: foam owns the pipeline (providers, batch processors, OTLP export to the foam fleet endpoint, opt-in key-list redaction — zero redaction by default), turns on automatic tier-1/2 instrumentation, and ships a small set of never-throw helpers. Configure with Foam::Otel.init(name:, environment:, enabled:, token:); the ingest token is passed EXPLICITLY — the fleet convention is to read it from the FOAM_OTEL_TOKEN environment variable and hand it to init. The gem never reads the token (or any config) from the environment itself. Built to docs/BASE_PACKAGE_SPEC.md; full usage in the README (shown on the source page and on rubydoc.info, not on the RubyGems gem page).
