Monitoring Guidelines

Apply these monitoring principles to ensure system reliability, performance visibility, and proactive issue detection.

Core Monitoring Principles

• Monitor the four golden signals: latency, traffic, errors, and saturation
• Implement monitoring as code for reproducibility
• Design monitoring around user experience and business impact
• Use SLOs (Service Level Objectives) to guide alerting decisions
• Balance comprehensive coverage with actionable insights

Key Metrics to Monitor

Application Metrics

• Request rate (requests per second)
• Error rate (percentage of failed requests)
• Response time (p50, p90, p95, p99 latencies)
• Active connections and concurrent users
