I'm trying to read NFS read and write data, but io fields in /proc/net/rpc/nfsd overflow (32-bit counter). I can keep track of overflow by reading the data from this file frequent enough and accounting for overflow myself. However I was wondering if there was another place where this data was stored/written that perhaps doesn't overflow at 32bits.

Are you using a 32- or 64-bit Linux system and which one? –  mdpc Jan 17 '12 at 23:02
    
I'm using a 64-bit ubuntu system. –  loosebazooka Jan 17 '12 at 23:15
    
nfsstat does not suffice, right? –  yarek Jan 17 '12 at 23:24
    
I don't think so, so I want to get bytes read/bytes written. I looked over nfsstat and it seems to give me number of read/write rpc calls (perhaps I am mistaken). –  loosebazooka Jan 17 '12 at 23:39
