Official Sentry SDK for OpenTelemetry

This package allows you to send your OpenTelemetry trace data to Sentry via OpenTelemetry SpanProcessors.

If you are using @sentry/node, OpenTelemetry support is included out of the box. This package is only necessary if you are setting up OpenTelemetry support for Sentry yourself.

Installation

npm install @sentry/opentelemetry

# Or yarn
yarn add @sentry/opentelemetry

Note that @sentry/opentelemetry depends on the following peer dependencies:

• @opentelemetry/api version 1.0.0 or greater
• @opentelemetry/core version 1.0.0 or greater
• @opentelemetry/semantic-conventions version 1.0.0 or greater
• @opentelemetry/sdk-trace-base version 1.0.0 or greater, or a package that implements that, like @opentelemetry/sdk-node.

Usage

This package exposes a few building blocks you can add to your OpenTelemetry setup in order to capture OpenTelemetry traces to Sentry.

This is how you can use this in your app:

1. Initialize Sentry, e.g. @sentry/node!
2. Call setupEventContextTrace(client)
3. Add SentrySampler as sampler
4. Add SentrySpanProcessor as span processor
5. Add a context manager wrapped via wrapContextManagerClass
6. Add SentryPropagator as propagator
7. Setup OTEL-powered async context strategy for Sentry via setOpenTelemetryContextAsyncContextStrategy()

For example, you could set this up as follows:

import * as Sentry from '@sentry/node';
import {
  SentryPropagator,
  SentrySampler,
  SentrySpanProcessor,
  setupEventContextTrace,
  wrapContextManagerClass,
  setOpenTelemetryContextAsyncContextStrategy,
} from '@sentry/opentelemetry';
import { AsyncLocalStorageContextManager } from '@opentelemetry/context-async-hooks';

function setupSentry() {
  Sentry.init({
    dsn: 'xxx',
  });

  const client = Sentry.getClient();
  setupEventContextTrace(client);

  const provider = new BasicTracerProvider({
    sampler: new SentrySampler(client),
  });
  provider.addSpanProcessor(new SentrySpanProcessor());

  const SentryContextManager = wrapContextManagerClass(AsyncLocalStorageContextManager);

  // Initialize the provider
  provider.register({
    propagator: new SentryPropagator(),
    contextManager: new SentryContextManager(),
  });

  setOpenTelemetryContextAsyncContextStrategy();
}

A full setup example can be found in node-experimental.
