more a general thing, but I think I'd just call this |

Yea I was thinking about this yesterday, we ideally would export those as-is for the environments that do not support module hooks. Will make that change |

Preload skips mongoose channel subscribe
Medium Severity
For mongoose >=9.7, diagnostics-channel subscription runs only in the server-utils integration setupOnce, while preloadOpenTelemetry invokes instrumentMongoose alone. The IITM patcher no longer covers 9.7+, so mongoose work between preload and Sentry.init() (or any preload-only usage) is not traced.

Code wise LGTM. I think this one has not been done yet? #21803 (comment) (I would vote for that too)

l: undefined values are skipped, null not, so it seems like this was done on purpose. I think following is a little easier to read:
| ...(batchSize!=null ? {[DB_OPERATION_BATCH_SIZE]: batchSize} : {}), | |
| [DB_OPERATION_BATCH_SIZE]: batchSize??undefined |
Subscribe to mongoose 9.7's native diagnostics_channel tracing channels via bindTracingChannelToSpan, emitting stable OTel DB semconv. Narrow the vendored OTel patcher to < 9.7.0 to avoid double instrumentation.
…gration Runtimes that use the server-utils integration directly expose it to users, so 'channel' in the name leaks an implementation detail. Node imports it under an internal alias since it keeps its own composed mongooseIntegration.
Replace the conditional-spread pattern for optional attributes with `?? undefined`. Undefined-valued keys are dropped by the span backends, so this is equivalent while keeping all six attribute lines consistent.
Replace the ad-hoc `void Promise.resolve().then(...)` deferral with the shared `waitForTracingChannelBinding` util, matching the vercel-ai and redis integrations. It retries until the async context binding is available, so it also handles custom OTel setups where the binding isn't ready on the first tick.

Instruments mongoose >= 9.7 through its native
diagnostics_channeltracing channels instead of monkey-patching, the same way we did for redis/ioredis. The subscription lives inserver-utilsasmongooseChannelIntegration, and the nodemongooseIntegrationextends it (viaextendIntegration) to keep running the IITM patcher for mongoose < 9.7.The channel path emits the latest stable DB semconv, so there is an attribute drift. We did that for redis so I thought to do the same here, but we could match the legacy attributes and drop them later for v11 if that's what we want.
