# nfsstat(1)

display NFS statistics

## NAME

**nfsstat** – display NFS statistics

## SYNOPSIS

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

## DESCRIPTION

**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)](/sysctl/2.md). Otherwise the specified core and system will be used to fetch data by means of [kvm(3)](/kvm/3.md).

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
