The value of "Map output records"

Is there a way to get the value of "Map output records" from within the
Reducer ?
I want to know the total number of the "Map output records" while the
Reducer is running and I've noticed this value in the web interface shown
for each Map.
Or is there a way to read in Reducer the value of "Reduce input groups" ?

Thanks,
Dan
