OpenTelemetry Requests Instrumentation

Warnings

• breaking Instrumenting after importing 'requests' may result in incomplete tracing due to module caching.
  Fix: Ensure 'RequestsInstrumentor().instrument()' is called before importing 'requests'.
• gotcha Setting 'OTEL_PYTHON_REQUESTS_EXCLUDED_URLS' to exclude certain URLs may not work if the environment variable is not set correctly.
  Fix: Verify the environment variable is set with the correct regex patterns to exclude desired URLs.

Install

• pip install opentelemetry-instrumentation-requests Install OpenTelemetry Requests Instrumentation

Imports

• RequestsInstrumentor

  from opentelemetry.instrumentation.requests import RequestsInstrumentor

  Ensure correct import path to access the RequestsInstrumentor class.

Quickstart

This script sets up OpenTelemetry tracing, instruments the 'requests' library, and makes an HTTP GET request to 'https://api.example.com'.

import os
from opentelemetry.instrumentation.requests import RequestsInstrumentor
from opentelemetry import trace
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.resources import Resource, SERVICE_NAME

# Set up the OpenTelemetry SDK
resource = Resource.create({SERVICE_NAME: 'my-service'})
provider = TracerProvider(resource=resource)
provider.add_span_processor(BatchSpanProcessor(OTLPSpanExporter()))
provider.register()

# Instrument the 'requests' library
RequestsInstrumentor().instrument()

# Make an HTTP request
import requests
response = requests.get('https://api.example.com')
print(response.status_code)
