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] [interval] [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 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.
