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.
Valid 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.
- -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.
-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
- 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.
- -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.
