Goal

This specification defines formats to pass trace context information across systems. Our goal is to share this with the community so that various tracing and diagnostics products can operate together.

Reference Implementations

There are few open source implementations of this trace context specification available.

A simplistic regex-based implementation can be found in the test folder. This implementation has 100% compliance to the test suite.

Open Census has implementations for the following languages:

1. C#
2. Erlang
3. Go
4. Java
5. Node.js
6. Python
7. Ruby

.NET Framework will ship trace context specification support in the upcoming version. See Activity for implementation details.

Elastic has node.js implementation.

LightStep has Go implementation.
