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 system was mounted.	Each subsequent report	contains  sta‐
	      tistics 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 seconds apart.  if
	      the  interval parameter is specified without the <count> parame‐
	      ter, 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.
