NAME

nfsstat − Network File System statistics

SYNOPSIS

/usr/bin/nfsstat [-i interval] [-23cnsrz] [system]

DESCRIPTION

The nfsstat command displays statistical information about the Network File System (NFS) and Remote Procedure Call (RPC) interfaces in the kernel (by reading /dev/kmem).  It can also be used to reinitialize this information.  If no options are given, nfsstat displays both server RPC and NFS version 2 and version 3 information, and client RPC and NFS version 2 and version 3 information. 

The system argument specifies the file containing the system’s name list.  Otherwise, /vmunix is used.
