observability
Observability
Implement the three pillars of observability: logs, metrics, and traces.
The Three Pillars
| Pillar | Purpose | Key Question |
|---|---|---|
| Logs | Discrete events with context | What happened? |
| Metrics | Aggregated measurements | How much/many? |
| Traces | Request flow across services | Where did time go? |
Quick Pick
- Debug specific request? → Logs + Traces
- Alert on thresholds? → Metrics
- Understand system health? → All three
- Starting from zero? → Logs first, then metrics, then traces
