How to measure NFS throughput in RHEL5.5 ?

[dayangkuncn]

Guys,

I'm trying to measure how much data transferred between my NFS server
machine and a NFS client machine in each second while doing some NFS
file copy ops, I'm trying to read the "/proc/net/rpc/nfs" file, but
could not figure out what the numbers mean, following are some sample
output from the "/proc/net/rpc/nfs" file on both the NFS server machine
and the NFS client machine:


NFS Server Machine:
===================
# cat /proc/net/rpc/nfsd
rc 0 784559 4015980
fh 0 0 0 0 0
io 784552 0
th 8 0 3828.727 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000
ra 32 0 0 0 0 0 0 0 0 0 0 784552
net 4800540 0 4800538 1
rpc 4800539 0 0 0 0

0 0 0 0 0 0 0 0 0 0


NFS Client Machine:
===================
# cat /proc/net/rpc/nfs
net 0 0 0 0
rpc 11884 0 0
proc2 18 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
proc3 22 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
proc4 35 0 0 10003 137 180 135 0 0 180 135 90 0 45 45 0 0 0 270 261 134
45 0 0 0 0 45 0 0 0 0 135 0 0 0 0


My operating system is RHEL5.5, could someone help me to read these
numbers ?

Thanks very much in advance
