Existing instrumentations

Tracing information is collected on each host using the instrumented libraries and sent to Zipkin. When the host makes a request to another application, it passes a few tracing identifiers along with the request to Zipkin so we can later tie the data together into spans.

The following libraries exist to provide instrumentation on various platforms. Please refer to their individual documentation for setup and configuration guides.

OpenZipkin libraries

The following libraries are supported by the OpenZipkin authors and are hosted at the OpenZipkin GitHub group. You can reach out to the authors at the Zipkin Gitter chat.
