# RIC tracing helper library

The library includes a function for creating a tracer instance.

ToDo: tracer configuration options

## Usage

Create a global tracer

```c
    #include <opentracing/tracer.h>
    #include <tracelibcpp/tracelibcpp.hpp>

    opentracing::Tracer::InitGlobal(tracelibcpp::createTracer("my-service-name"));
```
Span context propagation between different software components in RIC is using a
TextMap carrier and JSON format serialization.
The [opentracing C++](https://github.com/opentracing/opentracing-cpp) Readme gives examples
how span context **inject** and **extract** with textmap can be done.
Serialization to JSON can be done with any JSON library.
