In this example, the application in main.cc initializes and registers a tracer
provider from the OpenTelemetry
SDK. The TracerProvider
is connected to two processor-exporter pipelines - for exporting
simultaneously to StdoutSpanExporter and InMemorySpanExporter. The
application then calls a foo_library which has been instrumented using the
OpenTelemetry
API.
Resulting telemetry is directed to stdout through the StdoutSpanExporter, and
saved as a variable (vector of spans) through InMemorySpanExporter.
See CONTRIBUTING.md for instructions on building and running the example.
