Observability

Distributed tracing, structured logging, and telemetry collection.

Observability for microservices: how to trace requests across service boundaries, correlate logs with traces, and collect telemetry without coupling your code to a specific backend.

Distributed Tracing

When service A calls service B calls service C, a single request fans out across processes, networks, and log streams. Distributed tracing gives you a unified timeline of that request — every hop, every latency contribution, every error — in one view. ...
