jaeger-zipkin

These components make Jaeger compatible with Zipkin instrumentation and transports.

For example, you can join traces with other Zipkin (B3) instrumented applications (such as Brave), and send spans to Zipkin on standard transports such as Http or Kafka.

Usage

To make Jaeger Zipkin-compatible, you need to register injectors and extractors, and configure a remote reporter.

B3 Propagation

Zipkin systems most often use B3 propagation. This includes setting and reading headers like "X-B3-TraceId". Once you register B3TextMapCodec, Jaeger can join traces started by other Zipkin instrumented applications.

For example:

b3Codec = new B3TextMapCodec();
tracer = new Tracer.Builder(serviceName, reporter, sampler)
                   .registerInjector(Format.Builtin.HTTP_HEADERS, b3Codec)
                   .registerExtractor(Format.Builtin.HTTP_HEADERS, b3Codec)
                   ...

Sending data to Zipkin

Zipkin supports transports including Http and Kafka. You can configure Jaeger to send to a Zipkin server with ZipkinSender.

For example:

reporter = new RemoteReporter(ZipkinSender.create("http://localhost:9411/api/v1/spans"));
tracer = new Tracer.Builder(serviceName, reporter, sampler)
                   ...
