observability

SLO-based alerting reduces noise by establishing actionable, symptom-based alerts using Service Level Objectives and error budgets. This strategy ensures you only trigger incident responses for critical failures rather than minor anomalies.

Telemetry metrics for microservice monitoring should include RED (Rate, Errors, Duration) and USE (Utilization, Saturation, Errors) patterns. Tracking these provides full-stack visibility into service performance and resource bottlenecks.

Liveness and readiness probes prevent restart loops by configuring health gating that checks service stability before routing traffic. This ensures graceful recovery and prevents the system from receiving requests it cannot handle.

The best telemetry strategy defines comprehensive metrics, logs, and traces to provide full-stack visibility. It standardizes instrumentation across multi-service environments to ensure outages are detected by telemetry rather than user complaints.

Error budgets should be used during architectural design phases when failure detection and incident response are critical. They establish actionable thresholds that balance feature velocity with service reliability requirements.
