Overview

This example shows how to use @opentelemetry/sdk-trace-base to instrument a simple Node.js application - e.g. a batch job.

Our example will export spans data simultaneously on Console and Jaeger, however you can run your code anywhere and can use any exporter that OpenTelemetry supports.
