OpenTelemetry Core provides constants and utilities shared by all OpenTelemetry SDK packages.
OpenTelemetry instrumentation for `lru-memoizer` function memoization using lru-cache
OpenTelemetry Jaeger propagator provides HTTP header propagation for systems that are using Jaeger HTTP header format.
Ledger logs central point
OpenTelemetry Web Tracer
OpenTelemetry instrumentation for user interactions as click events in a web application
A library to create a trace of your node app per Google's Trace Event format.
Extract and inject W3C TraceContext headers
Extension of nom to trace parser execution
w3c traceparents made simple
Shared identity, scope, and trace primitives for the local-first AI systems stack
Core types for tonin: Service builder, Config, Context, Error, runtime.
A2A HTTP client - WASM default, native testing support
A2A HTTP server - WASM default, native testing support
Native Rust SDK for AllStak: error monitoring, performance tracing, structured logging, and release-health sessions over the AllStak ingest protocol.
Tower middleware for rlg. Emits per-request structured access logs for any `tower::Service<http::Request<_>>` — axum, tonic, hyper, lambda_runtime — with method, path, status, latency, and trace-ID propagation.
Opinionated Rust microservice framework. Kubernetes-native, mesh-secured, MCP-by-default.
build.rs helper for tonin services. Wraps tonic-build with tonin conventions.
Client-side primitives shared between generated tonin service clients: AuthCtx, retry/circuit-breaker config, OTel propagation. Tiny dep tree — peer services depend on this without pulling in the server framework.
Google Cloud Trace Context Propagation Extension for the OpenTelemetry framework
SolidEvents captures controller, job, SQL, business and record-link events into a queryable trace graph.
Configure tracing using context sensitive filters, appenders, output templates in a completely non-intrusive fashion. Tracing can even be applied runtime as a response when certain conditions occur
Ruby gem providing ScoutAPM API client and MCP server tools for fetching traces, endpoints, metrics, errors, and insights. Integrates with Cursor IDE via Model Context Protocol.
Distributed tracing, error tracking, structured logging, and infrastructure metrics for Ruby applications. Ships data to the JustAnalytics platform via batched HTTP transport with automatic trace context propagation.
RLM.rb is a Ruby runtime spine for Recursive Language Models. It runs bounded, typed, auditable AI jobs over files, records, and application context. RLM.rb includes RubyLLM provider access, a dspy.rb signature adapter, the recursive prompt loop, file/context mounting, recursive sub-LM calls, typed final output, budget controls, trace events, and a best-effort trace_store hook.
Sashiko is a small Ruby gem that adds a declarative span DSL on top of OpenTelemetry, plus helpers for keeping trace context attached as work crosses Thread, Fiber, queue, HTTP, and Ractor boundaries. Includes a span-replay mechanism for emitting spans from Ractor workers, optional Faraday and Anthropic adapters, RBS signatures, and a Ruby::Box-aware `tracer:` injection path for multi-tenant observability.
