Tracing And Observability With Observe Decorator And Span Hierarchy

via “distributed-tracing-with-span-context-management”

AI observability platform for production LLM and agent systems.

Unique: Combines context manager and decorator patterns with OpenTelemetry's context API to provide automatic parent-child span relationships and trace ID threading without explicit parameter passing; _LogfireWrappedSpan class adds custom features like automatic exception capture and latency measurement on top of standard OpenTelemetry spans

vs others: Simpler API than raw OpenTelemetry (no manual span.start()/span.end() calls) while maintaining full OTLP compatibility; automatic context propagation is more ergonomic than Jaeger or Zipkin client libraries that require manual context threading
