It works, but you are trying to probe a 2D dimensional object in 3D: the
volume is 0. If you want to work with Mayavi/VTK, you should really be
embedded in 3D. Specificaly, the problem here is that the Delaunay filter
does not seem to work for flat points (neither Delaunay3D nor
Delaunay2D). This might be due to the VTK internals.

Well, ProbeFilter is the right way to probe a structure, the problem here
is that you don't have one.
