Getting Started Guide - Python

This is a simple application instrumented with OpenTelemetry Python. It demonstrates how to configure OpenTelemetry Python to send data to New Relic.

Requirements

• Python
• A New Relic account
• A New Relic license key

Running the application

1. Set the following environment variables to configure OpenTelemetry to send data to New Relic:

   export OTEL_SERVICE_NAME=getting-started-python
   export OTEL_RESOURCE_ATTRIBUTES=service.instance.id=123
   export OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED=true
   export OTEL_EXPORTER_OTLP_ENDPOINT=https://otlp.nr-data.net
   export OTEL_EXPORTER_OTLP_HEADERS=api-key=<your_license_key>
   export OTEL_ATTRIBUTE_VALUE_LENGTH_LIMIT=4095
   export OTEL_EXPORTER_OTLP_COMPRESSION=gzip
   export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf 
   export OTEL_EXPORTER_OTLP_METRICS_TEMPORALITY_PREFERENCE=delta

   • If your account is based in the EU, set the endpoint to: https://otlp.eu01.nr-data.net

2. Run the following command to install dependencies:

   python -m pip install -r requirements.txt
   opentelemetry-bootstrap -a install

3. Run the application with the following command and open http://localhost:8080/fibonacci?n=1 in your web browser to ensure it is working.

   opentelemetry-instrument --logs_exporter otlp python3 app.py

4. Experiment with providing different values for n in the query string. Valid values are between 1 and 90. Values outside this range cause an error which will show up in New Relic.
