Tornado instrumentation for OpenTelemetry
Project description
This library builds on the OpenTelemetry WSGI middleware to track web requests in Tornado applications.
Installation
pip install opentelemetry-instrumentation-tornado
Configuration
The following environment variables are supported as configuration options:
OTEL_PYTHON_TORNADO_EXCLUDED_URLS
A comma separated list of paths that should not be automatically traced. For example, if this is set to
export OTEL_PYTHON_TORNADO_EXLUDED_URLS='/healthz,/ping'
Then any requests made to /healthz and /ping will not be automatically traced.
Request attributes
To extract certain attributes from Tornado’s request object and use them as span attributes, set the environment variable OTEL_PYTHON_TORNADO_TRACED_REQUEST_ATTRS to a comma delimited list of request attribute names.
For example,
export OTEL_PYTHON_TORNADO_TRACED_REQUEST_ATTRS='uri,query'
will extract path_info and content_type attributes from every traced request and add them as span attributes.
