SpanKind.Client not supported

[king-11]

• Package Name: azure-monitor-opentelemetry
• Package Version: ^1.6.0
• Operating System: Mariner
• Python Version: 3.9.7

Describe the bug setting the kind of span to SpanKind.CLIENT results in it being shown as of type N/A in app insights dependency table and end-to-end transaction detail

To Reproduce Create a span and set the kind as client.

tracer = get_tracer(__name__)

@tracer.start_as_current_span(name="update_inference_run", kind=SpanKind.CLIENT)
def update_inference_run():
  print("hello world")

Expected behavior Client kind should have a proper type instead of being N/A

Thanks for the feedback, we’ll investigate asap.

SpanKind maps to itemType not type field in AppInsights. SpanKind.Cient maps to dependency type telemetry and SpanKind.Server maps to requests telemetry.

@lzchen but in the end to end transaction history it's being shown as N/A and not dependency

[lzchen]

The reason you are getting "N/A" for the TYPE field is because application insights expects manually created spans (spans that are created using start_as_current_span) to be of type "InProc", which is the default if you do not set a span kind. ApplicationInsights only expects SpanKind.Client spans created automatically from instrumentations.

tracer = get_tracer(__name__)

@tracer.start_as_current_span(name="update_inference_run")
def update_inference_run():
  print("hello world")

We do not recommend setting the spankind manually, as this is an unsupported scenario for our SDK.

What would it take to support this particular scenario, I can try implementing it if it makes sense to have this feature?

My specific use case is that am familiar that the provided function makes multiple call to Azure SQL which are shown as dependency but then the overall function being a single span can be declared as type Client.

I am not fully understanding the use case here. InProc spans are exported as dependencies type telemetry as well. If the ask is to be able to manually modify the data.type field to a specific value, this scenario is not supported.

If you would like to group together your telemetry, there are a lot of other ways you can achieve this, most nobly using span attibutes
