Set Up Performance

Learn how to enable performance monitoring in your app.

As soon as you define a tracesSampleRate for your Sentry SDK, Performance Monitoring will be enabled. This will automatically instrument and monitor the performance of your application.

If you’re adopting Performance in a high-throughput environment, we recommend testing prior to deployment to ensure that your service’s performance characteristics maintain expectations.

const Sentry = require("@sentry/node");
const { nodeProfilingIntegration } = require("@sentry/profiling-node");

// Ensure to call this before requiring any other modules!
  dsn: "",
  integrations: [
    // Add our Profiling integration

  // Add Performance Monitoring by setting tracesSampleRate
  // We recommend adjusting this value in production
  tracesSampleRate: 1.0,

  // Set sampling rate for profiling
  // This is relative to tracesSampleRate
  profilesSampleRate: 1.0,

See Automatic Instrumentation to learn about all the things that the SDK automatically instruments for you.

You can also manually start spans to instrument specific parts of your code. This is useful when you want to measure the performance of a specific operation or function.

See Custom Instrumentation on how to manually start spans.
