Python services instrumented with OpenTelemetry

This repo contains two simple Python services that have been instrumented with OpenTelemetry-Python that you can configure to export traces to your New Relic account!

The service main.py simply creates spans, while app.py does the same but includes Flask and Flask instrumentation.

Prerequisites

Run

  1. Run pip install -r requirements.txt.

  2. Set the following environment variables:

    export OTEL_EXPORTER_OTLP_ENDPOINT=otlp.nr-data.net:4317
export OTEL_EXPORTER_OTLP_HEADERS=api-key=<your_license_key_here>
    • Replace <your_license_key_here> with your New Relic account ingest license key.

You have two options

  1. To run the application that doesn't have Flask:

    python3 main.py
    • Run that command as many times as you like to generate trace data.
    • This application produces trace data reporting to a service called python-app.

  2. To run the application that contains Flask:

    python3 app.py
    • This application exposes a simple endpoint at http://127.0.0.1:5000/. You can either open it in a browser and refresh as many times as you like to generate trace data, or you can invoke it by running curl http://127.0.0.1:5000/.
    • This application produces trace data reporting to a service called python-flask-app.

View your data in the New Relic UI

Depending on which app you ran, you should see either python-app or python-flask-app under Services - OpenTelemetry in your New Relic account.
