Starlette Error & Performance Monitoring

Actionable insights to solve Starlette errors.

Getting Started is Simple

Grab the Sentry Python SDK:

pip install --upgrade sentry-sdk

Configure your DSN:

from starlette.applications import Starlette import sentry_sdk sentry_sdk.init( dsn="https://<key><project>", # 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, # If you wish to associate users to errors (assuming you are using # django.contrib.auth) you may enable sending PII data. send_default_pii=True, ) app = Starlette(routes=[...])

Traditional logging provides you with a trail of events. Some of those events are errors, but many times they’re simply informational. Sentry is fundamentally different because we focus on exceptions, or in other words, we capture application crashes. We discuss in more detail here and on our blog.

When Spring Boot is configured to generate Git information every event triggered by Sentry will have a release field set to the current Git commit ID that will enable Monitor Release Health Sentry feature. More details here.

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.
