Metrics and Observability in Technical Systems Questions

Focuses on selecting, instrumenting, and operating the metrics and observability tooling that reveal system health and product impact. Topics include choosing meaningful indicators for latency error rates throughput and capacity, defining service level objectives and service level indicators, designing dashboards and alerting, structured logging and distributed tracing approaches, linking technical telemetry to user experience and business KPIs, and practices for incident response and root cause analysis. Candidates should be able to explain trade offs in instrumentation overhead versus diagnostic value and how observability informs prioritization of reliability work.
