Summary
Implements logging, metrics, and distributed tracing with a strong opinion on structured logging and correlation from day one. Covers OpenTelemetry instrumentation, Prometheus metrics, SLO definition, and alert configuration. The principles are sharp: structured JSON logs always, alert on symptoms not causes, and use error budgets to drive shipping decisions. Includes concrete code for pino logging with correlation IDs and OpenTelemetry auto-instrumentation setup. Good coverage of cardinality traps and the USE/RED method for knowing which metrics actually matter. If you're moving past console.log and toward production observability, this gives you opinionated patterns that prevent common mistakes like high-cardinality explosions or alert fatigue.
