Flask Error Monitoring
Actionable insights to resolve Flask performance bottlenecks and errors. Improve your monitoring workflow with a full view of releases so you can mark Flask errors as resolved and prioritize live issues.
Getting Started is Simple
Installsentry-sdk from PyPI with theflask extra:
pip install --upgrade 'sentry-sdk[flask]'
Configure your DSN:
import sentry_sdkfrom flask import Flaskfrom sentry_sdk.integrations.flask import FlaskIntegrationsentry_sdk.init( dsn="https://<key>@sentry.io/<project>", integrations=[FlaskIntegration()], # Set traces_sample_rate to 1.0 to capture 100% # of transactions for Tracing. # We recommend adjusting this value in production, traces_sample_rate=1.0)app = Flask(__name__)

Flask Performance Monitoring
Within minutes after installing Sentry, software teams are able to trace Flaskperformance 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.
Flask Error Monitoring with Complete Stack Traces
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 Flask exceptions intuitively to eliminate noise.
Fill In the Blanks About Flask Errors
Expose the important events that led to each Flask 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.
Sentry helps our team fix the most important issues in each release.”
See the Full Picture of Any Flask Exception
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 Flask bug occur?
FAQs
Sentry supports every major language, framework, and library. You can browse each of themhere.
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 ourpricing 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.
