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] ] [mountpoint]...

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

mounstats 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.

 

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.
