NAME
       mountstats - Displays various NFS client per-mount statistics

SYNOPSIS
       mountstats  [-h|--help] [-v|--version] [-f|--file infile] [-S|--since sincefile] [ [-n|--nfs]
       | [-r|--rpc] | [-R|--raw] | [-x|--xprt] ] [mountpoint]...

       mountstats iostat [-h|--help] [-v|--version] [-f|--file infile] [-S|--since  sincefile]  [in‐
       terval] [count] [mountpoint]...

       mountstats  nfsstat [-h|--help] [-v|--version] [-f|--file infile] [-S|--since sincefile] [-3]
       [-4] [mountpoint]...

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 dis‐
              play 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 con‐
              tains statistics for the time since each file system was mounted.  Each subsequent re‐
              port  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 con‐
              tinuously.  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.
