## What it is
A collection of third-party extensions, instrumentation packages, propagators, detectors, exporters, samplers, bridges, and processors for OpenTelemetry-Go. It lets Go applications integrate OpenTelemetry tracing, metrics, and logs with popular frameworks, libraries, and cloud environments.

## Use cases
- instrument a Go HTTP server or gRPC service with OpenTelemetry tracing
- export Go application traces and metrics to Jaeger or Prometheus
- auto-instrument popular Go libraries like net/http, gin, or database drivers
- detect cloud provider resource metadata for telemetry attribution
- bridge existing Go logging frameworks into OpenTelemetry logs
- propagate trace context across services using custom propagation formats

## When to choose
- you are building Go services and want vendor-neutral distributed tracing and metrics
- you need instrumentation for third-party Go libraries without writing it yourself
- you want to export telemetry to multiple observability backends without code changes

## When to avoid
- your project is not written in Go
- you need the core OpenTelemetry API/SDK itself rather than extensions
- you need zero-code agent-based instrumentation rather than library-level instrumentation

## Facets
- artifact type: library
- maturity: active
- function: tracing, monitoring, logging, middleware
- domain: monitoring, developer-tools, microservices
- platform: go, windows, cross-platform
- tags: opentelemetry, observability, telemetry, distributed-tracing, metrics, instrumentation-libraries, cnfc, instrumentation, devops, linux, macos
