Monitoring is not about collecting every metric. It tells you when things break. It helps you fix them fast.
Most teams collect too much data. They find too few signals.
Focus on the four golden signals:
- Latency: Request time.
- Traffic: Request volume.
- Errors: Failed requests.
- Saturation: Capacity limits.
Stop the noise. Alerts must be actionable. If a 3 AM alert does not change your action, delete it.
Use levels of severity:
- Critical: Page on-call.
- Warning: Slack notification.
- Info: Dashboard log.
Use structured logging. Log in JSON with these fields:
- Timestamp.
- Level.
- Service.
- Trace ID.
- Message.
Use distributed tracing for microservices. It finds which service is slow. OpenTelemetry is the standard.
Build dashboards for your audience:
- Executives: High level health.
- Engineers: Debugging metrics.
- Operations: Infrastructure use.
Test your response. Run game days. Simulate failures. Do not let a production outage be your first test.
Write runbooks. Tell on-call engineers what to check. Turn stress into a process.
