Structured Logging and Distributed Tracing
Make your deployments observable with structured logs, correlation IDs, and distributed tracing so you can debug failures across services in your CI/CD pipeline.
The Three Pillars of Observability
Observability rests on three pillars: metrics, logs, and traces.
- Metrics tell you that something is wrong
- Logs tell you what happened
- Traces tell you where in a request flow it happened
Pipeline monitoring usually starts with metrics; this lesson deepens logs and traces.
Why Structured Logging
A plain text log line is hard to query. A structured log is a machine-readable record, usually JSON, with named fields.
Structured logs can be filtered, aggregated, and alerted on by tools like Loki, Elasticsearch, or Datadog.
