If *everyone* who writes a checker provides multiple metrics at once, that
kind of suggests that a single metric at a time isn't all that important.

I suspect you're going to have to write your own -- maybe from scratch,
maybe a wrapper around one you like.

Presumably they all ask for a url where nginx serves "stub_status", and
process the numbers returned. In your version, just ignore the numbers
you don't care about. (Or cache them and serve slightly-stale information,
to avoid making the same request three times in succession.)

Good luck with it,
