Golang Observability

Go observability helps you understand what your services are doing in production. You get five key signals: structured logs, metrics, traces, profiles, and user event tracking. Each signal answers a different question about your system. Together they give you full visibility into both machine behavior and user experience.

This skill guides you to add these signals to your Go code. It covers tools like slog for logging, Prometheus for metrics, and OpenTelemetry for tracing. You also learn about continuous profiling with pprof and setting up alerting and dashboards. The goal is to never consider a feature done until it is observable.

Engineers who build and run Go services benefit the most. Whether you are starting a new project or adding monitoring to an existing one, this skill gives you clear steps. It also helps with migrating older loggers and making your tracking compliant with privacy rules like GDPR.
