## DESCRIPTION



           The **mountstats** command displays various NFS client statisitics for
           each given _mountpoint_.
    
           If no _mountpoint_ is given, statistics will be displayed for all
           NFS mountpoints on the client.
    
       **Sub-commands**
           Valid mountstats(8) subcommands are:
    
           **mountstats**
                  Display a combination of per-op RPC statistics, NFS event
                  counts, and NFS byte counts.  This is the default sub-
                  command that will be executed if no sub-command is given.
    
           **iostat** Display iostat-like statistics.
    
           **nfsstat**
                  Display nfsstat-like statistics.
    


## OPTIONS



       **Options valid for all sub-commands**
           **-h, --help**
                  show the help message and exit
    
           **-v, --version**
                  show program's version number and exit
    
           **-f** _infile_ , **--file** _infile_
                  Read stats from _infile_ instead of _/proc/self/mountstats_.
                  _infile_ must be in the same format as _/proc/self/mountstats_.
                  This may be used with the **-S** |**--since** options to display the
                  delta between two different points in time.  This may not
                  be used with the _interval_ or _count_ options of the **iostat**
                  sub-command.
    
           **-S** _sincefile_ , **--since** _sincefile_
                  Show difference between current stats and those in
                  _sincefile_.  _sincefile_ must be in the same format as
                  _/proc/self/mountstats_.  This may be used with the **-f** |**--file**
                  options to display the delta between two different points
                  in time.  This may not be used with the _interval_ or _count_
                  options of the **iostat** sub-command.
    
       **Options specific to the mountstats sub-command**
           **-n, --nfs** Display only the NFS statistics
    
           **-r, --rpc**
                  Display only the RPC statistics
    
           **-R, --raw**
                  Display only the raw statistics.  This is intended for use
                  with the **-f** |**--file** and **-S** |**--since** options.
    
           **-x, --xprt**
                  Display only the transport statistics
    
       **Options specific to the iostat sub-command**
           _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.  This may not be used with the **-f** |**--file**
                  or **-S** |**--since** options.
    
           _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.  This may not be used with the **-f** |**--file** or
                  **-S** |**--since** options.
    
       **Options specific to the nfsstat sub-command**
           **-3** Show only NFS version 3 statistics.  The default is to show
                  both version 3 and version 4 statistics.
    
           **-4** Show only NFS version 4 statistics.  The default is to show
                  both version 3 and version 4 statistics.
