Observability Stack
Overview
Production observability using the three pillars (metrics, logs, traces) with OpenTelemetry as the collection standard. Covers metric design, alerting strategies, dashboard patterns, and cost management.
The Three Pillars
| Pillar | What | Tool Stack | When |
|---|---|---|---|
| Metrics | Numeric time-series data | Prometheus + Grafana | Trend detection, alerting, capacity |
| Logs | Structured event records | Loki / ELK / CloudWatch | Debugging, audit trails, forensics |
| Traces | Request flow across services | Tempo / Jaeger / X-Ray | Latency analysis, dependency mapping |
All three must be correlated via trace context (trace_id, span_id) for effective debugging.
