AWS XRay UDP exporter for the OpenTelemetry framework

Messaging API

Official Ruby SDK for Langfuse, providing LLM tracing, observability, and prompt management capabilities

This exporter has been deprecated. To export your OTLP traces from OpenTelemetry SDK directly to Datadog Agent, please refer to OTLP Ingest in Datadog Agent: https://docs.datadoghq.com/tracing/setup_overview/open_standards/#otlp-ingest-in-datadog-agent. opentelemetry-exporters-datadog is Datadog’s trace exporter for the OpenTelemetry Ruby tracing library, which is used to trace requests across web servers, databases and microservices. The exporter formats and sends these traces to a Datadog Agent so that they can be ingested, stored, and analyzed with Datadog.

Splunk OpenTelemetry Ruby distribution

Ruby SDK for ARCP: envelope and message model, fiber-based runtime, client, WebSocket / stdio / in-memory transports, SQLite-backed resume log, capability negotiation, leases with budget and expiration, streamed results, and OpenTelemetry trace propagation. Built on socketry/async.

Adds OpenTelemetry tracing to ask-rb LLM operations. Subscribes to ask-instrumentation events and creates spans for chat completions, embeddings, tool calls, and more.

Epsagon provides tracing to Ruby applications for the collection of distributed tracing and performance metrics to simplify complex architectures, eliminate manual work, visualize and correlate data to identify and fix problems fast.

A simplified Ruby SDK for ErrorDebugger, wrapping OpenTelemetry for easy integration.

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).
