Best practices regarding Sentry in worker threads

[pavlos163]

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
