nfsstat(1)

nfsstat1

Display nfs statistics

Usage

nfsstat [-cs] [-M core] [-N system] [-w wait]

Overview

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(2). Otherwise the 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.

Files

/bsd

default kernel namelist

/dev/kmem

default memory file
