Overview
Combine metrics, logs and operational context to understand service health.
Design considerations
Monitoring checks known conditions; observability helps investigate why a system behaves as it does. Collect useful metrics, logs and events with reliable timestamps. Define service priorities and a baseline before setting alerts.
Operational practice
Alert on actionable symptoms and assign ownership. Track capacity and recurring incidents. Keep dashboards readable, protect operational data and rehearse response and recovery procedures.
