Distributed Tracing support #2167

Closed eedorenko closed 2 years ago

eedorenko commented 2 years ago

I have followed the guidance on distributed tracing. I have an updated iothub_ll_telemetry_sample working as expected and sending messages with tracestate property. I can see this system property in the message on the IoT Hub side. But! IoT Hub doesn't log anything under DistributedTracing category. Is this functionality still alive?

Hi @eedorenko. Let me look into that. Just for my knowledge, how are you setting up the diagnostic? AKA sending it to a storage archive, stream to event hub, etc.

eedorenko commented 2 years ago

@asergaz Yes, I can see this for all messages

I can also that the message arrives at IoT Hub and it has tracestate system property

Hi @danewalton, the diagnostic is configured with "Send to Log Analytics workspace" option.

Hi @eedorenko after asking around this is currently not in a working state. We are working to remove the documentation which you had linked. Sorry for the confusion. I'll consider this closed for now.
