How dynatrace decide if a call is sync or async ?

[Yosi_Neuman]

Hi guys,

Customers are asking how dynatrace decide if service calls are sync one or async?

Didn't find any documentation on that

Anyone can elaborate on this please?

hi , could you explain more, please?

I see in one transaction, calls are marked as asynchronous, but the thread ID and trace ID are the same for all these calls. As per my understanding, for an async call, a new thread is created.

I believe - it is by traces, you should see polling requests after the initial.
if you have polling indeed.

If this fire-and-forget async not sure.
