Important Changes

• Add server runtime metrics aggregator

The release adds alpha support for Sentry developer metrics in the server runtime SDKs (@sentry/node, @sentry/deno, @sentry/nextjs server-side, etc.). Via the newly introduced APIs, you can now flush metrics directly to Sentry.

To enable capturing metrics, you first need to add the metricsAggregator experiment to your Sentry.init call.

Sentry.init({
  dsn: '__DSN__',
  _experiments: {
    metricsAggregator: true,
  },
});

Then you'll be able to add counters, sets, distributions, and gauges under the Sentry.metrics namespace.

// Add 4 to a counter named `hits`
Sentry.metrics.increment('hits', 4);

// Add 2 to gauge named `parallel_requests`, tagged with `type: "a"`
Sentry.metrics.gauge('parallel_requests', 2, { tags: { type: 'a' } });

// Add 4.6 to a distribution named `response_time` with unit seconds
Sentry.metrics.distribution('response_time', 4.6, { unit: 'seconds' });

// Add 2 to a set named `valuable.ids`
Sentry.metrics.set('valuable.ids', 2);

• node: Rework ANR to use worker script via an integration

The ANR tracking integration for Node has been reworked to use an integration. ANR tracking now requires a minimum Node version of 16 or higher. Previously you had to call Sentry.enableANRDetection before running your application, now you can simply add the Anr integration to your Sentry.init call.

import * as Sentry from '@sentry/node';

Sentry.init({
  dsn: 'https://public@dsn.ingest.sentry.io/1337',
  integrations: [new Sentry.Integrations.Anr({ captureStackTrace: true, anrThreshold: 200 })],
});
