    # 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,

    # 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,

FAQs

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.

Sentry now supports suspect commits for Starlette applications, which helps you identify which code changes might have caused errors. Once set up, Sentry will:

  • Show suspect commits that might have introduced errors
  • Link to the specific lines of code in your repository
  • Suggest potential assignees based on who authored the suspect commits

For more information on setup, read the docs.

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.
