OpenTelemetry Falcon Tracing

This library builds on the OpenTelemetry WSGI middleware to track web requests in Falcon applications.

Installation

pip install opentelemetry-instrumentation-falcon

Configuration

Exclude lists

To exclude certain URLs from being tracked, set the environment variable OTEL_PYTHON_FALCON_EXCLUDED_URLS with comma delimited regexes representing which URLs to exclude.

For example,

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

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

Request attributes

To extract certain attributes from Falcon's request object and use them as span attributes, set the environment variable OTEL_PYTHON_FALCON_TRACED_REQUEST_ATTRS to a comma delimited list of request attribute names.

For example,

export OTEL_PYTHON_FALCON_TRACED_REQUEST_ATTRS='query_string,uri_template'

will extract path_info and content_type attributes from every traced request and add them as span attritbues.
