Nope - the idea is you have a dashboard which brings such thing to one's attention.

There are a few options floating around (which I'll try and find again..) - one is a script which emails an image of a dashboard to a list of users with a link. It's not rule based of course, just an image.

And there's an Idea which you can push up which is for this very feature.

Still not in 9.2, but see FAQ:  Rule-based Alert for a host of third-party options.
