Context

Evergreen has done work to augment the existing otelmongo instrumentation with additional attributes and by making some of the existing attributes more usable/readable. Our monitor.

It lets us do queries like slowest query by:
query
stripped query (something like query shape)
stack trace (helpful to find the code responsible for the slow query)

Also all of the above for the size of the response.

Definition of done

Additional attributes are implemented in the official otelmongo library.

Pitfalls

The attributes we added are high cardinality. This is fine for Honeycomb but maybe some OTel backends don't handle this well.
