Tracer tracer = initTracer("hello-world"); new Hello(tracer).sayHello(helloTo); Note that we are passing a string hello-world to the init method. Take OpenTracing for a HotROD Ride involves successive optimizations of a Go-based Ride-on-Demand demonstration service, all informed by tracing data. This can be done in two ways: Tracer.start_active_span() creates a new Span and automatically activates it.
It uses modern JavaScript, is built with TypeScript and combines elements of OOP (Object Oriented Progamming), FP (Functional Programming), and FRP (Functional Reactive Programming). The scenario will be a simple Hello World Producer/Consumer.

Traces in OpenTracing are defined implicitly by their Spans. In other words, it translates the calls to the OpenTracing API to Elastic APM and thus allows for reusing existing instrumentation. Implementation.
