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 <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.
