nfsstatdisplay 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 statistics will be obtained from the running system by calling sysctl(3). Otherwise the specified core and system will be used to fetch data by means of kvm(3).

The options are as follows:

Display client statistics only.
Extract values associated with the name list from the specified core instead of the default /dev/kmem.
Extract the name list from the specified system instead of the default /bsd.
Display server statistics only.
Display a shorter summary of NFS activity for both the client and server at wait second intervals.
