Set Up Profiling

With profiling, Sentry allows you to collect and analyze performance profiles from real user devices in production to give you a complete picture of how your application performs in a variety of environments.

Enable Performance Monitoring

Profiling depends on Sentry’s performance monitoring product being enabled beforehand. To enable performance monitoring in the SDK:

Sentry.init({
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
  tracesSampleRate: 1.0,
});

Check out the performance setup documentation for more detailed information on how to configure sampling. Setting the sample rate to 1.0 means all transactions will be captured.

Enable Profiling

To enable profiling, set the profilesSampleRate:

Sentry.init({
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
  tracesSampleRate: 1.0,
  _experiments: {
    // profilesSampleRate is relative to tracesSampleRate.
    // Here, we'll capture profiles for 100% of transactions.
    profilesSampleRate: 1.0,
  },
});
