You can collect more data automatically when you include instrumentation libraries from the OpenTelemetry community. Fundamentally, though, nothing prevents the logs to adopt the same context propagation concepts. The code example shows how to use the tracer.start_as_current_span() method to start, make the span current, and end the span within its context. Ask questions, find answers, and connect. the specified context, the created span will be a root span. Change the way teams work with solutions designed for humans and built for impact. # Create a new root span, set it as the current span in context, # Attach a new child and update the current span, # Close child span, set parent as current, # Close parent span, set default span as current, # Explicit parent span assignment is done via the Context, set_preferred_tracer_provider_implementation, importlib.metadata.version(instrumenting_library_name). Or maybe I misunderstood how those benchmarks are supposed to be interpreted. If you're not using Flask, that's fine - this guide will also work with Django, FastAPI, and more.

Link class. required steps: To add an attribute to a span, call the span's set_attribute method. This is a closed issue and I don't want this comment of yours to be overlooked because of that. It might even be feasible for tracer.start_as_current_span and tracer.start_as_current_span_async to recognise when they're used to decorate the wrong kind of function, but I recall async-coroutine detection to be somewhat woolly and easy to fool.
