observability-and-instrumentation

Instrument code for production monitoring by adding structured logging, metrics, tracing, and alerting to ensure system behavior is visible and diagnosable for post-launch incident response.

RED metrics track Rate, Errors, and Duration for services and resources. You track them using Prometheus to measure request throughput, failure rates, and latency for production visibility.

Implement distributed tracing with OpenTelemetry to trace cross-service requests, allowing on-call engineers to diagnose system behavior and pinpoint failures across production services.

The best way to set up alerting for on-call engineers is configuring symptom-based alerts for actionable events, ensuring notifications trigger only for significant production issues requiring intervention.

Yes, you can use Prometheus with OpenTelemetry to implement metrics tracking and distributed tracing, covering production monitoring requirements for structured logging and cross-service request diagnosis.

Structured logging formats log entries as parseable data, enabling better log analysis tools to filter, search, and correlate production events during post-launch monitoring and incident response.
