OpenTracing OkHttp Client Instrumentation

OpenTracing instrumentation for OkHttp client.

Configuration

Preferred way how to instrument OkHttpClient is to use TracingCallFactory:

Call.Factory client = new TracingCallFactory(okHttpClient, tracer);
client.newCall(request)...

or use OkHttpClient directly. However when doing multiple async requests simultaneously, parent spans created before invoking the client are not properly inferred.

OkHttpClient client = TracingInterceptor.addTracing(new OkHttpClient.Builder(), tracer)
client.newCall(request)...

Development

./mvnw clean install
