Tornado

(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.

Install

Install sentry-sdk from PyPI:

Copied
pip install --upgrade sentry-sdk

If you're on Python 3.6, you also need the aiocontextvars package:

Copied
pip install --upgrade aiocontextvars

Configure

Initialize the SDK before starting the server:

Copied
import sentry_sdk
from sentry_sdk.integrations.tornado import TornadoIntegration

sentry_sdk.init(
    dsn="https://examplePublicKey@o0.ingest.sentry.io/0",
    integrations=[TornadoIntegration()]
)

# Your app code here, without changes

class MyHandler(...):
    # ...

Behavior

  • 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.

  • Each request has a separate scope. Changes to the scope within a view, for example setting a tag, will only apply to events sent as part of the request being handled.

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