This project showcases how to instrument a microservice written in Java using the OpenTelemetry SDK to produce telemetry data to compatible observability backends.

The simplest way to play with this code is running everything local:

docker compose up -d

Alternatively, you can have the microservice sending telemetry data to AWS. Traces will be sent to X-Ray and the metrics will be sent to CloudWatch. This is possible thanks to the AWS Distro for OpenTelemetry that provides out-of-the-box integration with AWS services. Before running the code; make sure to configure your AWS credentials in your machine, as the code will use them to connect with the target services.

1. Run the collector

sh run-collector.sh

2. Run the microservice

sh run-microservice.sh

3. Invoke the API

curl -X GET http://localhost:8888/hello
