If you don't see any profiling data in, you can try the following:

  • Ensure that performance monitoring is enabled.
  • Ensure that the automatic instrumentation is sending performance data to Sentry by going to the Performance page in
  • If the automatic instrumentation is not sending performance data, try using custom instrumentation.
  • Enable debug mode in the SDK and check the logs.

The feature was experimental prior to version 1.17.0. To update your SDK to the latest version, remove profiles_sample_rate from _experiments and set it in the top-level options.

      "profiles_sample_rate": 1.0,  # for versions before 1.17.0
