My app needs to include the parent span id in python log messages. opentelemetry.instrumentation.LoggingInstrumentor unfortunately doesn't add the parent span id to the LogRecord. So, how do I obtain the Parent Span ID from the context of a child span?
I searched far and wide through python opentelemetry code and don't see a way to synchronously obtain the parent span id.
For example, my app uses
FlaskInstrumentor().instrument_app(app). By the time that the get() or post() method gets called, flask instrumentation has already started a new span (probably viawith trace.get_tracer().start_as_current_span(...):`). So, my code doesn't see the span id from the traceparent or b3 headers.I need to be able to obtain the Parent Span ID in my logging.Filter subclass so that I could add the Parent Span ID to the log record.
