nfsiostat(8)						      System Manager's Manual						      nfsiostat(8)

NAME

       nfsiostat - Emulate iostat for NFS mount points using /proc/self/mountstats

SYNOPSIS

       nfsiostat [[<interval>] [<count>]] [<options>][<mount_point>]

DESCRIPTION

       The nfsiostat command displays NFS client per-mount statisitics.

       <interval>
	      specifies the amount of time in seconds between each report.  The first report contains statistics for the time since each file sys-
	      tem was mounted.	Each subsequent report contains statistics collected during the interval since the previous report.

       <count>
	      If the <count> parameter is specified, the value of <count> determines the number of reports generated at <interval> seconds  apart.
	      if the interval parameter is specified without the <count> parameter, the command generates reports continuously.

       <options>
	      Define below

       <mount_point>
	      If  one  or  more  <mount  point> names are specified, statistics for only these mount points will be displayed.	Otherwise, all NFS
	      mount points on the client are listed.

OPTIONS

       -a  or  --attr
	      displays statistics related to the attribute cache

       -d  or  --dir
	      displays statistics related to directory operations

       -h  or  --help
	      shows help message and exit

       -l LIST or  --list=LIST
	      only print stats for first LIST mount points

       -p  or  --page
	      displays statistics related to the page cache

       -s  or  --sort
	      Sort NFS mount points by ops/second

       --version
	      show program's version number and exit
