How to disable instrumentation in Sentry v8?

[lilouartz]

I am suspecting that v8 instrumentation is causing pretty major performance hit when querying PostgreSQL, i.e. I am seeing a major difference when I load Sentry vs I do not load.

I want to keep Sentry but without any of the OTEL instrumentations. How do I do that?

It depends a bit on what you want to achieve. To disable the pg instrumentation you can filter the default integrations:

Sentry.init({
  integrations(integrations) {
    return integrations.filter(integration => integration.name !== 'Postgres');
  },
});

Although, using the instrumentation should not add too much overhead.

does this disable the code from being instrumented or does this just suppress what Sentry reports?

That will actually disable code from being instrumented.

Thank you!

Just to confirm, would this also disable instrumentation when ENABLE_TRACING is false?

Sentry.init({
  autoInstrumentRemix: config.ENABLE_TRACING,
  dsn: config.SENTRY_DSN,
  environment: config.ENVIRONMENT,
  normalizeDepth: 7,
  profilesSampleRate: config.ENABLE_TRACING ? 1 : 0,
  registerEsmLoaderHooks: config.ENABLE_TRACING,
  release: config.RELEASE_VERSION,
  skipOpenTelemetrySetup: !config.ENABLE_TRACING,
  tracesSampleRate: config.ENABLE_TRACING ? 1 : 0,
});
