Performance Monitoring for Flask apps

Application Performance Monitoring with Airbrake makes it easy to:

  • Understand high-level performance: Quickly see a broad performance overview for your whole application.
  • Monitor user satisfaction: Measure user satisfaction with your app performance using Apdex.
  • Catch problem routes: Identify routes with slow or error-prone performance.
  • Analyze granular performance metrics: Zoom into specific endpoints to see time spent in the DB, view, cache, external requests, and more.
  • Dive into database performance: Analyze SQL database queries being called and how long they take.
  • Track your background jobs: Monitor background job performance, track job failures and durations.

Flask Support

The pybrake package makes it quick and easy to monitor your Flask app’s performance. It only takes a few minutes to start collecting real performance data so let’s jump right in!

Step 1: Install the latest version of pybrake

Airbrake for Flask uses our official Python notifier pybrake. To install run:

pip install -U pybrake

Step 2: Configure the Airbrake Flask middleware

Replace the placeholder project_id and project_key values from the example below with the real values from your project’s setting page.

Note: Flask integration uses Flask signals and therefore requires the blinker library.

from flask import Flask
import pybrake.flask

app = Flask(__name__)

app.config['PYBRAKE'] = dict(
app = pybrake.flask.init_app(app)


Great job! If you’ve used this example in your app, you can visit your Airbrake project’s Performance Dashboard to see your performance data! Soon enough you’ll have more insights into your application’s performance. In the meantime why not check out the Performance Dashboard features. Have questions about Performance Monitoring?
