| # OpenTracing Shim | ||
|
|
||
| [![Apache License][license-image]][license-image] | ||
|
|
||
| The OpenTracing shim is a bridge layer from OpenTelemetry to the OpenTracing API. | ||
| It takes an OpenTelemetry Tracer and exposes it as an implementation compatible with | ||
| that of an OpenTracing Tracer. | ||
|
|
||
| ## Usage | ||
|
|
||
| Use the TracerShim wherever you initialize your OpenTracing tracers. | ||
| There are 2 ways to expose an OpenTracing Tracer: | ||
|
|
||
| 1. From the global OpenTelemetry configuration: | ||
|
|
||
| ```cpp | ||
| auto tracer_shim = TracerShim::createTracerShim(); | ||
| ``` | ||
|
|
||
| 1. From a provided OpenTelemetry Tracer instance: | ||
|
|
||
| ```cpp | ||
| auto tracer_shim = TracerShim::createTracerShim(tracer); | ||
| ``` | ||
|
|
||
| Optionally, one can also specify the propagators to be used for the OpenTracing `TextMap` | ||
| and `HttpHeaders` formats: | ||
|
|
||
| ```cpp | ||
| OpenTracingPropagators propagators{ | ||
| .text_map = nostd::shared_ptr<TextMapPropagator>(new CustomTextMap()), | ||
| .http_headers = nostd::shared_ptr<TextMapPropagator>(new trace::propagation::HttpTraceContext()) | ||
| }; | ||
|
|
||
| auto tracer_shim = TracerShim::createTracerShim(tracer, propagators); | ||
| ``` | ||
|
|
||
| If propagators are not specified, OpenTelemetry's global propagator will be used. | ||
