NAME <\/a> <\/h2>\n

nfsstat \u2212 list NFS statistics<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

nfsstat<\/b> [OPTION<\/i>]…<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

Print only client-side statistics.<\/p>\n

\u2212n, \u2212\u2212nfs<\/b><\/p>\n

Print only NFS statistics. The default is to print both NFS and RPC information.<\/p>\n\n\n\n\n
<\/td>\n\n

\u22122<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Print only NFS v2 statistics. The default is to only print information about the versions of NFS<\/b> that have non-zero counts.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

\u22123<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Print only NFS v3 statistics. The default is to only print information about the versions of NFS<\/b> that have non-zero counts.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

\u22124<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Print only NFS v4 statistics. The default is to only print information about the versions of NFS<\/b> that have non-zero counts.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

\u2212m, \u2212\u2212mounts<\/b><\/p>\n

Print information about each of the mounted NFS<\/b> file systems.<\/p>\n

If this option is used, all other options are ignored.<\/p>\n

\u2212r, \u2212\u2212rpc<\/b><\/p>\n

Print only RPC statistics.<\/p>\n

\u2212o<\/b> facility<\/i><\/p>\n

Display statistics for the specified facility, which must be one of:<\/p>\n\n\n\n\n\n\n\n\n\n
<\/td>\n\n

nfs<\/b><\/p>\n<\/td>\n

<\/td>\n\n

NFS protocol information, split up by RPC call.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

rpc<\/b><\/p>\n<\/td>\n

<\/td>\n\n

General RPC information.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

net<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Network layer statistics, such as the number of received packets, number of TCP connections, etc.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

fh<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Usage information on the server\u2019s file handle cache, including the total number of lookups, and the number of hits and misses.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

rc<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Usage information on the server\u2019s request reply cache, including the total number of lookups, and the number of hits and misses.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

io<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Usage information on the server\u2019s io statistics; bytes read and written.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

ra<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Usage information on the server\u2019s read ahead cache, including the ra cache size, the depth of ra cache hits, and ra cache misses.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

all<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Display all of the above facilities.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

\u2212v, \u2212\u2212verbose<\/b><\/p>\n

This is equivalent to \u2212o all<\/b>.<\/p>\n

\u2212l, \u2212\u2212list<\/b><\/p>\n

Print information in list form.<\/p>\n

\u2212S, \u2212\u2212since<\/b> file<\/i><\/p>\n

Instead of printing current statistics, nfsstat<\/b> imports statistics from file<\/i> and displays the difference between those and the current statistics. Valid input file<\/i>s may be in the form of \/proc\/net\/rpc\/nfs<\/b> (raw client stats), \/proc\/net\/rpc\/nfsd<\/b> (raw server stats), or saved output from nfsstat<\/b> itself (client and\/or server stats). Any statistics missing from a saved nfsstat<\/b> output file<\/i> are treated as zeroes.<\/p>\n

\u2212Z[interval], \u2212\u2212sleep=[interval]<\/b><\/p>\n

Instead of printing current statistics and immediately exiting, nfsstat<\/b> takes a snapshot of the current statistics and pauses until it receives SIGINT<\/b> (typically from Ctrl-C<\/b>), at which point it takes another snapshot and displays the difference between the two. If interval<\/i> is specified, nfsstat<\/b> will print the number of NFS<\/b> calls made since the previous report. Stats will be printed repeatedly every interval<\/i> seconds.<\/p>\n

EXAMPLES <\/a> <\/h2>\n

nfsstat \u2212o all \u2212234<\/b><\/p>\n

Show all information about all versions of NFS<\/b>.<\/p>\n

nfsstat \u2212\u2212verbose \u2212234<\/b><\/p>\n

Same as above.<\/p>\n

nfsstat \u2212o all<\/b><\/p>\n

Show all information about active versions of NFS<\/b>.<\/p>\n

nfsstat \u2212\u2212nfs \u2212\u2212server \u22123<\/b><\/p>\n

Show statistics for NFS<\/b> version 3 server.<\/p>\n

nfsstat \u2212m<\/b><\/p>\n

Show information about mounted NFS<\/b> filesystems.<\/p>\n

DISPLAY <\/a> <\/h2>\n

The Flags<\/b> output from the \u2212m<\/b> option is the same as the flags give to the mount<\/b> command.<\/p>\n

FILES <\/a> <\/h2>\n

\/proc\/net\/rpc\/nfsd<\/b><\/p>\n

procfs<\/b>-based interface to kernel NFS server statistics.<\/p>\n

\/proc\/net\/rpc\/nfs<\/b><\/p>\n

procfs<\/b>-based interface to kernel NFS client statistics.<\/p>\n

\/proc\/mounts<\/b><\/p>\n

procfs<\/b>-based interface to the mounted filesystems.<\/p>\n

SEE ALSO <\/a> <\/h2>\n

rpc.nfsd<\/b>(8). nfs<\/b>(5).<\/p>\n

BUGS <\/a> <\/h2>\n

The default output has been changed. To get the old default output you must run nfsstat \u2212\u2212auto \u22122<\/b>.<\/p>\n

The function of the \u2212v<\/b> and \u2212a<\/b> options have changed. The \u2212a<\/b> option is now reserved for future use. The \u2212v<\/b> does what the \u2212a<\/b> option used to do, and the new \u2212[234]<\/b> options replace the \u2212v<\/b> option.<\/p>\n

The Display<\/b> section should be more complete.<\/p>\n
