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).

OpenTelemetry-based observability instrumentation for the LaunchDarkly Ruby SDK. Works with Rails, Sinatra, and any Rack-compatible framework.

The 'APM' (Application Performance Monitoring) Ruby gem provides developers with comprehensive insights into their software applications' performance and behavior. By monitoring end-user experiences, profiling code execution, tracing transaction flows, and tracking resource utilization, the gem assists in identifying bottlenecks, errors, and areas for optimization. Real-time alerts, error analysis, and trend tracking contribute to maintaining a smooth user experience, enhancing application scalability, and ensuring efficient resource utilization.

Add OpenTelemetry instrumentation to your Minato Rails applications, enabling tracing with Google Cloud Trace integration or any other trace service.

Prosody offers Ruby bindings to the Prosody Kafka client, providing features for message production and consumption, including configurable retry mechanisms, failure handling strategies, and integrated OpenTelemetry support for distributed tracing.

Auto-instruments Rails, Sidekiq, Postgres, OpenAI, and Anthropic.

Researchable's Loggable relies on lograge and elastic's ecs format to log events in a way that is easy to ingest by logstash. This enables log correlation with traces across multiple services.
