The osg::Stats support allows you to get various stats from the scene graph traversals. The stats handler in src/osgViewer/StatsHander.cpp is a good tool to use if you want an onscreen report - just press 's' a couple of times in osgviewer to see them. You can also use this code as a guide of how to enable stats collection in your own app without the stats handler being used. I must add that the number of vertices shown by the stats handler is the total number of vertices in the geometeries that are sent to OpenGL, it will be an upper bound on how much vertices are on screen. It would be a perfect match to the number of vertices on screen as geometries may be partially offscreen or occluded.
