NFSSTAT(1) BSD Reference Manual NFSSTAT(1)
nfsstat - display NFS statistics
nfsstat [-cs] [-M core] [-N system] [-w wait]
nfsstat displays statistics kept about NFS client and server activity. If neither -M nor -N option was specified statics will be obtained from the running system by calling sysctl(3) routine. Otherwise specified core and system will be used to fetch data by means of kvm(3). The options are as follows: -c Display client statistics only. -M core Extract values associated with the name list from the specified core instead of the default /dev/kmem. -N system Extract the name list from the specified system instead of the default /bsd. -s Display server statistics only. -w wait Display a shorter summary of NFS activity for both the client and server at wait second intervals.
