how to tracing the operation between two processes #232
Description
i have such a scene to trace: process_a send data to process_b, I need to track the entire process of sending data until it is accepted by process_b. the two process communicate with share memory.
now create root_span at process_a and sent the Spancontext to process_b, and create child_span with root_span's SpanContext .but this still can't track the process of delivery. i want to end the root_span in process_b, but how to do this？
Anyone knows the solution to solve this problems, thank you!！

既然是process_a创建的root_span，为啥不是自己finish呢？

@chiaqi we do not encourage this behavior of sharing spans between process, and we suggest to have 2 different spans:
You can see the "delivery" time as the difference root_span.start_time - child_span.start_time.
Does this answer your question, let me know if this does not work and I can try to help more.

@bogdandrutu thanks for your answer
I can see the delivery time , but how to intuitively display it on the stackdriver?
Is there a better solution for this scenario?
