2. Set these two environment variables to send data to your New Relic account:

export OTEL_EXPORTER_OTLP_HEADERS=api-key=<your_license_key>
export OTEL_EXPORTER_OTLP_ENDPOINT=https://otlp.nr-data.net
export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
export OTEL_ATTRIBUTE_VALUE_LENGTH_LIMIT=4095

• Make sure to use your ingest license key
• If your account is based in the EU, set the endpoint to: https://otlp.eu01.nr-data.net

3. Set this environment variable to name the demo app:

export OTEL_SERVICE_NAME=getting-started-java
export OTEL_RESOURCE_ATTRIBUTES=service.instance.id=123

4. Run the following command

../gradlew bootRun

4. To generate traffic, in a new terminal tab run the following command

./load-generator.sh

5. To shut down the program, run the following in both shells or terminal tabs: ctrl + c.
