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 seconds
              apart. if the interval parameter is specified without the <count> parameter, the command generates reports contin-
              uously.

       <options>
              Define below

       <mount_point>
              If  one or more <mount point> names are specified, statistics for only these mount points will be displayed.  Oth-
              erwise, all NFS mount points on the client are listed.
