SYNOPSIS
nfsiostat [[<interval>] [<count>]] [<options>][<mount_point>]

if the interval parameter is specified without the <count> parameter, the command generates reports continuously.
<options>

<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.
OPTIONS
-a or --attr
