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.
