Actionable insights to resolve Fastify performance bottlenecks and errors. Improve your Fastify monitoring workflow with a full view of releases so you can mark errors as resolved and prioritize live issues.
Add @sentry/node
as a dependency:
npm install --save @sentry/node
You need to create a file named instrument.js
that imports and initializes Sentry:
import * as Sentry from '@sentry/node'; // Ensure to call this before importing any other modules! Sentry.init({ dsn: 'https://examplePublicKey@o0.ingest.sentry.io/0', // Add Tracing by setting tracesSampleRate // We recommend adjusting this value in production tracesSampleRate: 1.0, });
You need to require or import the instrument.js
file before requiring any other modules in your application. This is necessary to ensure that Sentry can automatically instrument all modules in your application:
// Import this first! import './instrument'; // Now import other modules import Fastify from 'fastify'; import * as Sentry from '@sentry/node'; const app = Fastify(); Sentry.setupFastifyErrorHandler(app); // Add your routes, etc. app.listen({port: 3030});

See all platformsSentry works with OpenTelemetry to provide a simple configuration process, and rich distributed tracing context across all the libraries and frameworks used in your application. Regardless of your chosen tech stack.
Quickly identify Fastify performance issues and view full end-to-end distributed trace to see the exact, poor-performing API call and surface any related errors.
See the Fastify source code at each frame instead of settings for just line and column numbers. Get proper asynchronous context tracking — like thread-local store — in a way that fits Node’s concurrency model.
See what the app was doing when the Fastify error occurred: HTTP requests, database queries, console loft statements, etc.
Profiling lets you see what parts of your code are consuming the most resources, like CPU or memory, in your application— so you can optimize them before end user experience is impacted. Test your application performance in any environment, including in production, without writing manual tests or extensive troubleshooting.

Aggregate errors by factors like request details, user ID, and event level to see what’s new, a priority, or a trend.
Assign custom key-value tags to reproduce the error environment specific to your application, business, and users.
