Correct, this is only for logging and profile output.

I don't think there's a need to attach anything to explain. Adding state to currentOp might be useful, but it's not a priority.

So you want to include stuff for logging/profile output, not for explain, correct?

Or is the goal to support more information in currentOp output, while it is running only?

Sorry, pressed Enter too soon.

(I think this ticket might already exist, but I just spent 5min looking for it and couldn't find it)

Currently RocksDB adds counters to each query in a pretty hacky way: https://github.com/mongodb-partners/mongo/commit/eaecfc73a0c0b547b91708cf98233f48b46608d0. It would be great to have a generic way of adding storage-engine specific counters to a query.
