AWS Distro for OpenTelemetry Python - Integration Testing App - Manual instrumentation - Flask

This application validates the continual integration of manual instrumentation with the AWS Distro for OpenTelemetry Python and the AWS X-Ray back-end service. Validation is done using the AWS Test Framework for OpenTelemetry.

Application interface

The application uses Flask to expose the following routes:

  1. /
    • Ensures the application is running.
  2. /outgoing-http-call
    • Makes a HTTP request to aws.amazon.com using the popular requests Python library.
  3. /aws-sdk-call
    • Makes a call to AWS S3 to list buckets for the account corresponding to the provided AWS credentials.

Running the integration testing application:

For more information on running a python application using manual instrumentation, please refer to the ADOT Python Manual Instrumentation Documentation. In this context, the ADOT Collector is being run locally as a sidecar.

Option 1: Use the utility shell script to run the application in a local docker container integration-test-apps/run_integration_test_app.sh flask manual

Option 2: Use python3 to run the application directly in your terminal configured with OpenTelemetry parameters LISTEN_ADDRESS=127.0.0.1:8080 OTEL_EXPORTER_OTLP_ENDPOINT=127.0.0.1:4317 python3 integration-test-apps/manual-instrumentation/flask/application.py

Sending metrics to Amazon CloudWatch is not validated due to pending updates to metric collection logic in ADOT Python.
