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]
       [interval] [count] [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  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.
