We use http://dhcpd-pools.sourceforge.net/ for same goal and with failover setup, too.
It gives extensive stats like this:

shared net name     first ip           last ip            max   cur    percent  touch   t+c  t+c perc     bu  bu perc
HotSpot             X.X.X.65         - X.X.Y.126         62     4      6.452     49    53    85.484      9   14.516
