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
          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.
