Understanding Production Systems
You cannot fix what you cannot see. Observability combines metrics, logs, and traces into a coherent picture of system health. It is the difference between reactive firefighting and proactive capacity planning.
These resources cover structured logging with JSON, Prometheus metric collection, Grafana dashboard design, distributed tracing with OpenTelemetry, and alerting strategies. Learn how to reduce mean time to detection and resolution in production environments.
