Long story short. Last updated May 29, Want to have a go at drafting what that "current practice" for this might look like? The part about me personally being uninterested in logging B3-Trace-Id as a response header is mostly not wanting to answer questions about why everyone doesn't do this to higher orders of people. Many distributed tracing scenarios may be broken when only a subset of calls participated in a distributed trace were recorded.

Trace context HTTP headers format. This section describes the binding of the distributed trace context to traceparent and tracestate http. Also, the methods OPTIONS and TRACE SHOULD NOT have side effects, and so A response SHOULD include any header fields that indicate optional.
The HTTP TRACE method performs a message loop-back test along the path to the target resource, providing a useful debugging mechanism. The final recipient of the request should reflect the message received, excluding some fields described below, back to the client as the message.
Then, a user can search by the request id they know.

In this case, since congo wrote traceparentits tracestate entry should be left-most. Note: In this case, the value t61rcWkgMzEis the result of Base64 encoding the Trace-ID b7ad6bthough such manipulations are not required in tracestate. Selfishness of my time aside, I'm just saying we should think this through and export things very carefully to larger orders of people. Clicking or hovering over requests reveals more information about them.

The main purpose of this header is to provide additional vendor-specific trace-identification information across different distributed tracing systems.

If a random number generator leverages any user identifiable information like IP address as seed state - this information may be exposed.

Current specification assumes the version is set to At certain load recording information about every incoming and outgoing request becomes prohibitively expensive. Some services initiating or receiving a call MAY choose to restart a traceparent field to eliminate those risks completely.
We recommend the wide deployment and use of this recommendation. However, it is possible that a sequence of several requests is non- idempotent, even if all of the methods executed in that sequence are idempotent.
Trace response header
|Get me? It had the information I needed. The partial GET method is intended to reduce unnecessary network usage by allowing partially-retrieved entities to be completed without transferring data already held by the client.
Various techniques include: probability sampling sample 1 out of distributed traces by flipping a coindelayed decision make collection decision based on duration or a result of a calldeferred sampling let callee decide whether information about this request need to be collected.
The left-most position lets the next server know which tracing system corresponds with traceparent.
