mountstats(8) System Manager's Manual mountstats(8)
mountstats - Displays various NFS client per-mount statistics
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]...
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 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.
