Observability¶
Logs, metrics, traces. The three pillars that turn "production is broken" into "production is broken because the order-service p99 spiked at 14:32 after the deploy at 14:30."

- Observability basics - the three pillars, golden signals, when to use which
- Eventual consistency - the failure modes you'll see in dashboards
Compare¶
- Observability and monitoring services - CloudWatch vs Azure Monitor vs Cloud Operations, Datadog, New Relic
- LLM observability - LangSmith, Langfuse, Helicone, Phoenix, Braintrust
Reference¶
- Architecture pattern: Chaos engineering
- Troubleshooting: AWS
- Troubleshooting: Azure
- Troubleshooting: GCP
- Troubleshooting: Kubernetes
Build¶
- Set up a monitoring stack - Prometheus, Grafana, alerting end-to-end
- Set up an eval harness - LLM-side observability and regression detection
