This library allows tracing HTTP requests made by the urllib3 library.

Installation

pip install opentelemetry-instrumentation-urllib3

Usage

import urllib3
from opentelemetry.instrumentation.urllib3 import URLLib3Instrumentor

def strip_query_params(url: str) -> str:
    return url.split("?")[0]

URLLib3Instrumentor().instrument(
    # Remove all query params from the URL attribute on the span.
    url_filter=strip_query_params,
)

http = urllib3.PoolManager()
response = http.request("GET", "https://www.example.org/")

Configuration

Request/Response hooks

The urllib3 instrumentation supports extending tracing behavior with the help of request and response hooks. These are functions that are called back by the instrumentation right after a Span is created for a request and right before the span is finished processing a response respectively. The hooks can be configured as follows:

from typing import Any

from urllib3.connectionpool import HTTPConnectionPool
from urllib3.response import HTTPResponse

from opentelemetry.instrumentation.urllib3 import RequestInfo, URLLib3Instrumentor
from opentelemetry.trace import Span

def request_hook(
    span: Span,
    pool: HTTPConnectionPool,
    request_info: RequestInfo,
) -> Any:
    pass

def response_hook(
    span: Span,
    pool: HTTPConnectionPool,
    response: HTTPResponse,
) -> Any:
    pass

URLLib3Instrumentor().instrument(
    request_hook=request_hook,
    response_hook=response_hook,
)

Exclude lists

To exclude certain URLs from being tracked, set the environment variable OTEL_PYTHON_URLLIB3_EXCLUDED_URLS (or OTEL_PYTHON_EXCLUDED_URLS as fallback) with comma delimited regexes representing which URLs to exclude.

For example,

export OTEL_PYTHON_URLLIB3_EXCLUDED_URLS="client/.*/info,healthcheck"

will exclude requests such as https://site/client/123/info and https://site/xyz/healthcheck.
