OpenTelemetry Requests Instrumentation
======================================
|pypi|
.. |pypi| image:: https://badge.fury.io/py/opentelemetry-instrumentation-requests.svg
:target: https://pypi.org/project/opentelemetry-instrumentation-requests/
This library allows tracing HTTP requests made by the
`requests <https://requests.readthedocs.io/en/master/>`_ library.
Installation
------------
::
pip install opentelemetry-instrumentation-requests
Configuration
-------------
Exclude lists
*************
To exclude certain URLs from being tracked, set the environment variable ``OTEL_PYTHON_REQUESTS_EXCLUDED_URLS``
(or ``OTEL_PYTHON_EXCLUDED_URLS`` as fallback) with comma delimited regexes representing which URLs to exclude.
For example,
::
export OTEL_PYTHON_REQUESTS_EXCLUDED_URLS="client/.*/info,healthcheck"
will exclude requests such as ``https://site/client/123/info`` and ``https://site/xyz/healthcheck``.
