Updated Candidate Recommendation for Trace Context

August 13th, 2019

The Distributed Tracing Working Group invites implementations of an updated Candidate Recommendation of Trace Context. This specification defines standard HTTP headers and a value format to propagate context information that enables distributed tracing scenarios. The specification standardizes how context information is sent and modified between services. Context information uniquely identifies individual requests in a distributed system and also defines a means to add and propagate provider-specific context information. Comments are requested by 9 September 2019.
