Opentracing Plugin Example

This plugin embraces OpenTelemetry Autoconfiguration using environment-based properties to configure OpenTelemetry SDK.

Run Opentracing Plugin Example

Running the Example Demo

To run the example, simply type mvn verify from this directory, or mvn -PnoServer verify if you want to start and create the broker manually.

NOTE: You must have jeager running at http://localhost:16686. You can learn more about Jeager here

command to start your jeager instance docker run -p 16686:16686 -p 14250:14250 jaegertracing/all-in-one:<your_version>

After seeing a Build Success, open the browser, connect to your Jeager running instance and check for spans.

Customise Opentracing Plugin Example

The tracing.properties has configuration properties that autoconfigure Opentelemetry Exporter . We reconfigured it and used Jeager as the default exporter, sending data through at http://localhost:14250 You can change this by choosing to use:

  • otlp exporter , by uncommenting (removing #) the following

    • otlp enabler: otel.traces.exporter=otlp
    • otlp endpoint: otel.exporter.otlp.endpoint=http://localhost:4317 Change port and host to match your running instance.
    • otlp traces-endpoint: otel.exporter.otlp.traces.endpoint=http://localhost:4317 Change port and host to match your running instance.

  • Zipkin Exporter , by uncommenting (removing #) the following

    • Zipkin enabler: otel.traces.exporter=zipkin
    • Zipkin endpoint: otel.exporter.zipkin.endpoint=http://localhost:9411/api/v2/spans. Change port and host to match your running instance.

    Note: command to start Zipkin instance docker run -p 9411:9411 openzipkin/zipkin

You can also change the default service name from opentracing_plugin to any string by changing the value of otel.service.name
