Falcon instrumentation for OpenTelemetry
Project description
This library builds on the OpenTelemetry WSGI middleware to track web requests in Falcon applications.
Currently, only Falcon v2 is supported.
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.
