Observability with Structured Logging and Tracing
See what your functions are really doing. Learn structured JSON logging, distributed tracing with AWS X-Ray, and custom metrics for production-grade observability.
The Three Pillars of Observability
Observability rests on logs, metrics, and traces. Together they answer what happened, how much, and where the time went across your serverless system.
Why Structured Logging?
Plain text logs are hard to search. Structured (JSON) logs let CloudWatch Logs Insights filter and aggregate by field, turning logs into queryable data.
