go/observability

Go observability setup involves configuring slog for structured logging, exposing a /metrics endpoint for Prometheus, and initializing an OpenTelemetry tracer at application startup to achieve production-grade visibility.

Structured logging in Go services uses slog to ensure consistent log formats and easy ingestion. This approach provides standardized logger setup with safe defaults, making logs highly parseable for downstream analysis.

Adding health checks to a Go application provides readiness signals that support production-grade reliability and automated health management. This pattern initializes dedicated health endpoints for continuous monitoring.

OpenTelemetry tracing in Go enables end-to-end tracing and context propagation across microservices. Initializing the tracer at startup ensures distributed operations maintain visibility throughout service boundaries.

Prometheus metrics integration in Go uses counters, histograms, and a /metrics endpoint for live monitoring. This standardized pattern provides safe defaults and validation without requiring complex external dependencies.

A standardized Go observability pattern provides a cohesive stack for logging, metrics, and tracing. This ensures reliable visibility, maintainable instrumentation, and safe defaults rather than fragmented tool configurations.
