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.
