(New in version : 0.6.3)

The Tornado integration adds support for the Tornado Web Framework. A Tornado version of 5 or greater and Python 3.6 or greater is required.

  1. Install sentry-sdk from PyPI:

     $ pip install --upgrade sentry-sdk==0.16.0
  2. If you’re on Python 3.6, you also need the aiocontextvars package:

    $ pip install --upgrade aiocontextvars
  3. Initialize the SDK before starting the server:

    import sentry_sdk
    from sentry_sdk.integrations.tornado import TornadoIntegration
    # Your app code here, without changes
    class MyHandler(...):


  • The Tornado integration will be installed for all of your apps and handlers.

  • All exceptions leading to a Internal Server Error are reported.

  • Request data is attached to all events: HTTP method, URL, headers, form data, JSON payloads. Sentry excludes raw bodies and multipart file uploads. Sentry also excludes personally identifiable information (such as user ids, usernames, cookies, authorization headers, IP addresses) unless you set send_default_pii to True.

  • Logging with any logger will create breadcrumbs when the Logging integration is enabled (done by default).
