Emulate iostat for nfs mount points using /proc/self/mountstats
nfsiostat [[<interval>] [<count>]] [<options>][<mount_point>]
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.
-a or --attr
displays statistics related to the attribute cache
-d or --dir
displays statistics related to directory operations
-h or --help
shows help message and exit
-l LIST or --list=LIST
only print stats for first LIST mount points
-p or --page
displays statistics related to the page cache
-s or --sort
Sort NFS mount points by ops/second
--version
show program's version number and exit
