SYNOPSIS

10       nfsiostat [[<interval>] [<count>]] [<options>][<mount_point>]
11

DESCRIPTION

13       The nfsiostat command displays NFS client per-mount statisitics.
14
15       <interval>
16              specifies the amount of time in  seconds  between  each  report.
17              The  first  report  contains  statistics for the time since each
18              file system was mounted.  Each subsequent report  contains  sta‐
19              tistics collected during the interval since the previous report.
20
21       <count>
22              If  the  <count>  parameter  is  specified, the value of <count>
23              determines the number of reports generated at seconds apart.  if
24              the  interval parameter is specified without the <count> parame‐
25              ter, the command generates reports continuously.
26
27       <options>
28              Define below
29
30       <mount_point>
31              If one or more <mount point> names are specified, statistics for
32              only  these  mount points will be displayed.  Otherwise, all NFS
33              mount points on the client are listed.
