Setup

• Node.js application with main thread + worker threads (using worker_threads module)
• Sentry initialized in both main thread and each worker thread
• Mongoose used for database operations
• Worker threads perform scheduled tasks (Bree) and exit after completion

Sentry configuration

Sentry.init({
 enabled: true,
 dsn: process.env.SENTRY_DSN,
 environment: process.env.NODE_ENV,
 integrations: [
 Sentry.nodeProfilingIntegration(),
 Sentry.extraErrorDataIntegration(),
 Sentry.httpIntegration({
 ignoreOutgoingRequests: (url) => url.includes("someservice")
 }),
 Sentry.mongoIntegration(),
 Sentry.mongooseIntegration()
 ],
 profilesSampler: () => 0.2,
 tracesSampler: () => 0.2
});

Questions

• Is it safe to call Sentry.init() in multiple worker threads with the same configuration?
• Do the mongoIntegration() and mongooseIntegration() create shared state that could cause issues across worker threads?
• Are there recommended patterns for using Sentry with Node.js worker threads?

Environment

• Node.js: v20.x
• Sentry version: 9.17.0
