OpenTelemetry Annotation Demo

This repo shows how to use annotations on method level to create spans and export the traces to see the Distributed tracing for End to End transaction. Uses AspectJ features to create traces for the methods applied with Annotations.

InjectSpan Annotation

Creates new trace spans and makes the span as current span.

InjectSpanToContext Annotation

Adds spans to current context and makes the span as current span.

InjectChildSpanToContext Annotation

Pre-requisites

• Docker
• JAVA 8
• Maven

To run the demo, switch to the docker directory and run(Windows machine, Haven't tried in MAC or Linux):

docker compose up -d

The demo exposes the following backends:

• Jaeger at http://localhost:16686
• Zipkin at http://localhost:9411
• Prometheus at http://localhost:9090
• Kibana at http://localhost:5601

Run JAVA app to export the traces using Annotations

To run java application, navigate to root of the project and open command prompt to run command:

mvn package

The target folder will be generated upon succesfull build. Run the jar file:

java -jar opentelemetry-annotations-0.0.1-SNAPSHOT-jar-with-dependencies.jar

Traces should be exported to Zipkin, Jaeger and Elastic (Kibana)..

To clean up any docker container from the demo run docker compose down from this directory.
