Sentry

autotel-sentry bridges Autotel traces to Sentry via a SpanProcessor and optional SentryPropagator.

Prerequisites

• Sentry must be initialized before Autotel init()
• Set instrumenter: 'otel' in Sentry.init()

Installation

npm install autotel autotel-sentry @sentry/node

Minimal Setup

import * as Sentry from '@sentry/node';
import { init } from 'autotel';
import { createSentrySpanProcessor } from 'autotel-sentry';

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  tracesSampleRate: 1.0,
  instrumenter: 'otel', // Required
});

init({
  service: 'my-app',
  spanProcessors: [createSentrySpanProcessor(Sentry)],
});

With sentry-trace and Baggage Propagation

For cross-service trace continuity:

import * as Sentry from '@sentry/node';
import { init } from 'autotel';
import { createSentrySpanProcessor, SentryPropagator } from 'autotel-sentry';
import { CompositePropagator } from '@opentelemetry/core';
import {
  W3CTraceContextPropagator,
  W3CBaggagePropagator,
} from '@opentelemetry/core';

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  tracesSampleRate: 1.0,
  instrumenter: 'otel',
});

init({
  service: 'my-app',
  spanProcessors: [createSentrySpanProcessor(Sentry)],
  propagator: new CompositePropagator({
    propagators: [
      new W3CTraceContextPropagator(),
      new W3CBaggagePropagator(),
      new SentryPropagator(),
    ],
  }),
});

Examples

• example-sentry — Autotel + Sentry bridge with createSentrySpanProcessor() for linked traces and errors.

How It Works

• Root OTel spans → Sentry transactions
• Child OTel spans → Sentry child spans
• OTel exception events → Sentry errors
• Spans for Sentry ingestion are filtered out (no infinite loops)
