Flask instrumentation for OpenTelemetry
Project description
This library builds on the OpenTelemetry WSGI middleware to track web requests in Flask applications.
Installation
pip install opentelemetry-instrumentation-flask
Configuration
Exclude lists
To exclude certain URLs from being tracked, set the environment variable OTEL_PYTHON_FLASK_EXCLUDED_URLS (or OTEL_PYTHON_EXCLUDED_URLS as fallback) with comma delimited regexes representing which URLs to exclude.
For example,
export OTEL_PYTHON_FLASK_EXCLUDED_URLS="client/.*/info,healthcheck"
will exclude requests such as https://site/client/123/info and https://site/xyz/healthcheck.
You can also pass the comma delimited regexes to the instrument_app method directly:
FlaskInstrumentor().instrument_app(app, excluded_urls="client/.*/info,healthcheck")Request/Response hooks
Utilize request/reponse hooks to execute custom logic to be performed before/after performing a request. Environ is an instance of WSGIEnvironment (flask.request.environ). Response_headers is a list of key-value (tuples) representing the response headers returned from the response.
def request_hook(span: Span, environ: WSGIEnvironment):
if span and span.is_recording():
span.set_attribute("custom_user_attribute_from_request_hook", "some-value")
def response_hook(span: Span, status: str, response_headers: List):
if span and span.is_recording():
span.set_attribute("custom_user_attribute_from_response_hook", "some-value")
FlaskInstrumentation().instrument(request_hook=request_hook, response_hook=response_hook)Flask Request object reference: https://flask.palletsprojects.com/en/2.0.x/api/#flask.Request
