support mongo-driver's db metrics #7983

minuk-dev · 2025-10-06T17:45:09Z

I cannot find the metrics support of otel for mongo-driver. If I'm wrong, please let me know. 🙇

Description

OTel guides

MongoDB client instrumentations SHOULD collect metrics according to the general Semantic Conventions for Database Client Metrics.
- ref. https://opentelemetry.io/docs/specs/semconv/database/mongodb/#metrics
However, there is no implementation for it.

Implementations

~~- Define & Implement NewPoolMonitor to collect database's connection pool metrics.~~
~~- Support db.client.operation.duration and db.client.response.returned_rows metrics:~~
~~- Limitation: In the doc (https://opentelemetry.io/docs/specs/semconv/database/database-metrics/), db.query.text is a opt-in attributes. But, mongo-driver does not provides this information. So, I left it as a todo comment. ~~

Support db.client.operation.duration metric.

Sample output as a prometheus format

Looking at this, I think it should be split into multiple PRs to get proper review.

The db.client.response.returned_rows is still in development. So we shouldn't expose it by default, as it may have breaking changes that would make migrations on our end quite a bunch of toil.
If you look at how we do experimental features on the core SDK, that would give you a hint.
This metric should be its own PR.

Similarly, all database connection pools semantic conventions are still under development. So they should also be hidden behind a feature flag.

Thank you for your review. I'll make flags to enable the development metrics.

@dmathieu
I think the development metrics' code can have many review comments. So, I removed the metrics in the development stage.
Do you want to review all of them at once, please let me know.

Could you fix the lint issues?

minuk-dev · 2025-11-13T13:37:30Z

Sorry. I didn't know there is lint. I fixed it.

But, some other CI is failed... I'm checking the reason.

dmathieu · 2025-11-13T13:45:33Z

Current failure is because of #8163

minuk-dev · 2025-11-13T13:48:32Z

And I found the changelog was wrong. I fixed it.
