-# Python Best Practices
-
-## Project Structure
-- Use src-layout with `amqp/`
-- Place tests in `tests/` directory parallel to `amqp/`
-- Keep configuration in `amqp/config/` or as environment variables
-- Store requirements in `pyproject.toml`
-- Place static files in `static/` directory
-- Use `templates/` for Jinja2 templates
-
-## Code Style
-- Follow Black code formatting
-- Use isort for import sorting
-- Follow PEP 8 naming conventions:
-  - snake_case for functions and variables
-  - PascalCase for classes
-  - UPPER_CASE for constants
-- Maximum line length of 100 characters
-- Use absolute imports over relative imports
-
-## Type Hints
-- Use type hints for all function parameters and returns
-- Import types from `typing` module
-- Use `Optional[Type]` instead of `Type | None`
-- Use `TypeVar` for generic types
-- Define custom types in `types.py`
-- Use `Protocol` for duck typing
-
-## Database
-- Use SQLAlchemy ORM
-- Implement database migrations with Alembic
-- Use proper connection pooling
-- Define models in separate modules
-- Implement proper relationships
-- Use proper indexing strategies
-
-## Authentication
-##- Use Flask-Login for session management
-##- Implement Google OAuth using Flask-OAuth
-##- Hash passwords with bcrypt
-##- Use proper session security
-##- Implement CSRF protection
-##- Use proper role-based access control
-
-## API Design
-##- Use Flask-RESTful for REST APIs
-##- Implement proper request validation
-##- Use proper HTTP status codes
-##- Handle errors consistently
-##- Use proper response formats
-##- Implement proper rate limiting
-
-## Testing
-- Use pytest for testing
-- Write tests for all routes
-- Use pytest-cov for coverage
-- Implement proper fixtures
-- Use proper mocking with pytest-mock
-- Test all error scenarios
-
-## Security
-##- Use HTTPS in production
-##- Implement proper CORS
-##- Sanitize all user inputs
-##- Use proper session configuration
-- Implement proper logging
-##- Follow OWASP guidelines
-
-## Performance
-##- Use proper caching with Flask-Caching
-##- Implement database query optimization
-##- Use proper connection pooling
-##- Implement proper pagination
-##- Use background tasks for heavy operations
-- Monitor application performance
-
-## Error Handling
-- Create custom exception classes
-- Use proper try-except blocks
-- Implement proper logging
-- Return proper error responses
-- Handle edge cases properly
-- Use proper error messages
-
-## Documentation
-- Use Google-style docstrings
-- Document all public APIs
-- Keep README.md updated
-- Use proper inline comments
-- Generate API documentation
-- Document environment setup
-
-## Development Workflow
-- Use virtual environments (venv)
-- Use or Implement pre-commit hooks
-- Use proper Git workflow
-- Follow semantic versioning
-- Use proper CI/CD practices
-- Implement proper logging
-
-## Dependencies
-##- Pin dependency versions
-##- Use requirements.txt for production
-- Separate dev dependencies
-##- Use proper package versions
-##- Regularly update dependencies
-- Check for security vulnerabilitie

+    # if FastAPI, then use
+    # FastAPIInstrumentor.instrument_app(app)
+

+    # Python Flask is now automatically instrumented to export details of each REST endpoint call.
+    # For Django based app, use 'opentelemetry-instrumentation-django' import instead. see here:
+    # https://opentelemetry-python.readthedocs.io/en/latest/examples/django/README.html for example
+    #
+    # If the used library has no instrumentation support in opentelemetry.io, then the trace
+    # can be started manually. In this code,
+    # 'trace' should be global shared variable, initialized once per application (see tracing.py)
+    # 'tracer' can be shared global or local variable, application can use multiple uniquely
+    #          named tracers, Jaeger will group the generated traces by the name of the tracer
+    #          that was used to start the Span. See this example code:
+    #
+    # tracer = trace.get_tracer(name)
+    #
+    # @app.route("/server_request")
+    # def server_request():
+    #     with tracer.start_as_current_span(
+    #         "server_request",
+    #         context=extract(request.headers),
+    #         kind=trace.SpanKind.SERVER,
+    #         attributes=collect_request_attributes(request.environ),
+    #     ):
+    #         # do the work here, like logging.info something and return response
+    #         logging.info(request.args.get("param"))
+    #         return "served"
+    #
+    # Note:
+    #    the otlp code looks for HTTP header named 'traceparent' that, if present, should contain
+    #    the otlp parent span identification, and the span created here will be made a child
+    #    of that parent span, indicating visually the progression of requests via different services
+    #    for as long as the current span is provided in the traceparent header to next service.
+
+    # 2. Metrics (Prometheus) configuration
+    # -------------------------------------
+    #
+    # Start Prometheus client
+    start_http_server(port=9464, addr="localhost")
+    # Initialize PrometheusMetricReader which pulls metrics from the SDK
+    # on-demand to respond to scrape requests (unlike Jaeger, which worls with push model - application
+    # pushes traces when those become available to Jaeger's collector. Prometheus works with pull model
+    # where it periodically polls pre-configured and/or discovered endpoints for metrics.
