opentelemetry-instrumentation-tornado 0.23b0

Tornado instrumentation for OpenTelemetry

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.
