Observability and Monitoring Questions

Cover the practices and tooling used to make services observable and to detect and diagnose production issues. Candidates should explain structured logging and log aggregation metrics design for latency error and throughput distributed tracing and correlation across services. They should know how to choose service level indicators and service level objectives set alerting thresholds to balance noise and signal design dashboards for triage and capacity planning and use sampling strategies for traces and logs. Observability should be tied to post incident analysis and reliability improvements.
