Healthy platforms rely on actionable visibility, not just dashboards. We outline a cost-aware, signal-driven approach to observability for modern systems.
Signals and sources
- Metrics for golden signals: latency, traffic, errors, saturation
- Logs for investigation; traces for causality
- RUM and synthetics for user perspective
SLOs and error budgets
- Define SLOs tied to user experience
- Use error budgets to govern release pace
Instrumentation
- Standardize with OpenTelemetry
- Propagate trace context through events and async jobs
Alerting without noise
- Alerts on SLO burn, not raw metrics
- Multi-window, multi-burn-rate policies
Cost management
- Sample high-volume traces; downsample logs
- Retain detailed data only where needed

FAQs
What’s the fastest way to get started? Instrument critical paths first, then expand to supporting services.
How do we avoid alert fatigue? Attach alerts to user-impacting SLOs and add runbooks.
Conclusion
Observability is an engineering product—treat it with clear requirements, budgets, and ownership.
