Your question is Golden Signals for Monitoring. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe your approach to monitoring and alerting, and what metrics are truly golden signals.
Explain how you choose service-level signals, distinguish actionable alerts from diagnostic telemetry, and prevent alert fatigue. Include the signal source, thresholding approach, ownership, escalation path, and how you verify that alerts detect customer-impacting failures without excessive false positives.
