Structured logging with OpenTelemetry trace correlation is designed by emitting JSON logs containing trace_id and span_id on every log line, integrating OpenTelemetry spans, and propagating W3C Trace Context across service and async boundaries for end-to-end traceability.

W3C Trace Context propagation across async boundaries is handled by defining a comprehensive tracing design that applies OpenTelemetry integration across components and runtime environments, ensuring traceability and correlation throughout real deployments.

PII redaction and retention policies for log aggregation are implemented by applying compliant data handling rules within the logging design, ensuring deterministic log schemas meet governance requirements across all emitted JSON logs.

Sampling strategies for errors and latency are configured by defining tailored sampling rules within the tracing design, linking logs to traces to enable quick incident investigation and user journey tracking without guesswork.

OpenTelemetry is needed to achieve end-to-end observability across multiple runtime environments because it provides the span integration and W3C Trace Context propagation required to correlate logs and traces across service boundaries and backends.

Your logging and tracing design lacks traceability across service boundaries because it needs a deterministic log schema with trace_id and span_id correlation, W3C Trace Context propagation, and consistent OpenTelemetry integration across all components.
