Install our Python SDK using pip:
pip install --upgrade sentry-sdk
Initialize the Python SDK with the Tornado integration in your
import sentry_sdk from sentry_sdk.integrations.tornado import TornadoIntegration sentry_sdk.init( dsn="https://examplePublicKey@o0.ingest.sentry.io/0", integrations=[ TornadoIntegration(), ], # Set traces_sample_rate to 1.0 to capture 100% # of transactions for performance monitoring. # We recommend adjusting this value in production, traces_sample_rate=1.0, ) # Your app code here, without changes class MyHandler(...): # ...
Within minutes after installing Sentry, software teams are able to trace Tornado performance issues back to a poor performing API call as well as surface all related code errors. Engineering Managers and Developers now have a single tool to optimize performance of their code and deliver fast customer experiences with Performance Monitoring.
See local variables in the stack for prod errors, just like in your dev environment. Introspect more deeply into the runtime and jump into the frame to get additional data for any local variable. Filter and group Tornado exceptions intuitively to eliminate noise.
Expose the important events that led to each Tornado exception: SQL queries, debug logs, network requests, past errors. Learn in which version a bug first appeared, merge duplicates, and know if things regress in a future release.
Aggregate errors by details like HTTP request, hostname, and app version to see what’s new, a priority, or a trend.
Assign custom tags to reproduce the error environment specific to your application, business, and users.
Find answers to key questions: How actionable is this error? In which app release did the Tornado bug occur?
You can get started for free. Pricing depends on the number of monthly events, transactions, and attachments that you send Sentry. For more details, visit our pricing page.
Sentry doesn’t impact a web site’s performance.
If you look at the configuration options for when you initialize Sentry in your code, you’ll see there’s nothing regarding minimizing its impact on your app’s performance. This is because our team of SDK engineers already developed Sentry with this in mind.
Sentry is a listener/handler for errors that asynchronously sends out the error/event to Sentry.io. This is non-blocking. The error/event only goes out if this is an error.
Global handlers have almost no impact as well, as they are native APIs provided by the browsers.
Here’s a quick look at how Sentry handles your personal information (PII).×
We collect PII about people browsing our website, users of the Sentry service, prospective customers, and people who otherwise interact with us.
What if my PII is included in data sent to Sentry by a Sentry customer (e.g., someone using Sentry to monitor their app)? In this case you have to contact the Sentry customer (e.g., the maker of the app). We do not control the data that is sent to us through the Sentry service for the purposes of application monitoring.Am I included?
We may disclose your PII to the following type of recipients:
