  Some information is kept, but not as much as RADIUS.

  We're always open for patches.  Adding some DHCP stats to v3 would be fine.

  In v4, the server is much more protocol independent.  There's a "stats" module which does statistics for any protocol (modulo some minor tweaking).  It can also add stats to any incoming packet, such as Status-Server.

  There's some minor tweaking to do for the stats module to finish it, but it's not a lot.
