Go Observability with OpenTelemetry
Overview
Modern Go applications require comprehensive observability through the three pillars: traces, metrics, and logs. OpenTelemetry provides vendor-neutral instrumentation for distributed tracing, Prometheus offers powerful metrics collection, and Go's slog package (1.21+) delivers structured logging with minimal overhead.
Key Features:
- 🔍 OpenTelemetry: Distributed tracing with context propagation
- 📊 Prometheus: Metrics collection with /metrics endpoint
- 📝 Structured Logging: slog with JSON formatting and correlation IDs
- 🎯 Auto-Instrumentation: HTTP/gRPC middleware patterns
- 💚 Health Checks: Kubernetes-ready readiness/liveness probes
- 🔄 Graceful Shutdown: Clean exporter shutdown and signal handling
When to Use This Skill
Activate this skill when:
- Instrumenting microservices for production observability
- Setting up distributed tracing across service boundaries
