Observability

In distributed systems, you can't see everything. Observability—logs, metrics, and traces—lets you understand what's happening across your services. This section covers the three pillars of observability: collecting and analyzing logs, measuring system behavior with metrics, tracing requests across service boundaries, and defining reliability objectives.

📄️ Logs and Structured Logging

Collect and analyze logs with structure and correlation IDs to understand system behavior.

📄️ Metrics and Monitoring

Measure system behavior with metrics using RED and USE methods to identify performance issues.

📄️ Distributed Tracing

Follow requests across microservices using distributed tracing.

📄️ SLO, SLI, SLA, and Error Budgets

Define and track reliability targets using service-level objectives.
