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.
