This one walks you through the full observability stack: structured logging with Pino, Prometheus metrics with proper histogram buckets, OpenTelemetry tracing, and Grafana dashboards using RED and USE methods. It's built around a five-step workflow from assessment to alerting, with working code samples for Node.js instrumentation and k6 load tests. The constraint list is smart about correlation IDs and avoiding alert fatigue. Use it when you're setting up monitoring for a new service or debugging production issues where logs alone aren't cutting it. The examples are production-ready, not toy demos, which saves you from the usual Stack Overflow hunt.
