LAYER 3 · INFRA · STAGE 3
Observability for FDEs
Quick answer
Logs, metrics and traces that show how a system behaves. If you cannot see a deployment working, you cannot prove it works.
Practise it
- 1. Add structured logs and a trace id
- 2. Chart latency and error rate
- 3. Set one alert that a human would act on
Where it sits
Stage 3 of the roadmap: Cloud and deployment. You can ship code to an environment you do not own and see it running.
