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/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. Register the Sentry context manager (SentryAsyncLocalStorageContextManager, or wrapContextManagerClass for a custom base)
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 {
  SentryAsyncLocalStorageContextManager,
  SentryPropagator,
  SentrySampler,
  SentrySpanProcessor,
  setupEventContextTrace,
  setOpenTelemetryContextAsyncContextStrategy,
} from '@sentry/opentelemetry';
import { context, propagation, trace } from '@opentelemetry/api';

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

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

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

  // Initialize the provider
  trace.setGlobalTracerProvider(provider);
  propagation.setGlobalPropagator(new SentryPropagator());
  context.setGlobalContextManager(new SentryAsyncLocalStorageContextManager());

  setOpenTelemetryContextAsyncContextStrategy();
}

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

Sentry Tracer Provider

SentryTracerProvider is a minimal OpenTelemetry tracer provider which creates native Sentry spans directly. It is useful when code uses the global OpenTelemetry API and you do not need the full OpenTelemetry SDK span processor and exporter pipeline.

import { trace } from '@opentelemetry/api';
import { SentryTracerProvider } from '@sentry/opentelemetry';

trace.setGlobalTracerProvider(new SentryTracerProvider());

const span = trace.getTracer('example').startSpan('work');
span.end();

In @sentry/node, this is the default tracer provider. To use the full OpenTelemetry SDK BasicTracerProvider instead, opt out with:

Sentry.init({
  dsn: 'xxx',
  openTelemetryBasicTracerProvider: true,
});

Providing openTelemetrySpanProcessors also falls back to the full OpenTelemetry SDK provider, since custom span processors require the SDK span pipeline. The SentryTracerProvider does not handle OpenTelemetry logs and metrics.
