observability-and-instrumentation

Instrument production code by adding structured logging, RED and USE metrics, and OpenTelemetry distributed tracing to make system behavior visible and diagnosable post-deployment.

Structured logging formats log data into consistent, queryable fields, enabling better searchability and analysis when diagnosing production system behavior and actionable alerting.

Yes, distributed tracing with OpenTelemetry provides service-to-service latency insights, helping you diagnose performance bottlenecks and monitor production system behavior effectively.

The best way to set up alerting is using symptom-based alerts that notify on actionable issues, ensuring production code remains observable and diagnosable without alert fatigue.

You need RED metrics for service rate, errors, and duration, and USE metrics for resource utilization and saturation, to comprehensively monitor production system health and performance.
