It is the same for me on nfs4 server on SL6.2

What statistics are you trying to get? What's wrong with standard way of
querying nfs server, "nfsstat -s" command?
It's much better than looking in proc, because the file you see there is
specific only to current linux kernel-mode nfs implementation, while
nfsstat -s *is* the correct and portable way across various systems.
