I hope you don't produce Cerenkov photons in tungsten. You won't because it's a metal and you have not specified a (real) index of refraction for tungsten. So, if you have specified only an index of refraction for the fiber, and no other material in your simulation, then all of your photons are generated in the fiber and nowhere else.

Now, if you have two dialectic materials and you need to count the generated photons depending on which material the current step is in, then I think you'd need to resort to counting in your UserSteppingAction where you know where you are and the number of secondaries generated in the current step - but maybe somebody else has a better idea?
