DESCRIPTION

20       The mountstats command displays various NFS client statisitics for each
21       given mountpoint.
22
23       If no mountpoint is given, statistics will be  displayed  for  all  NFS
24       mountpoints on the client.
25
26   Sub-commands
27       Valid mountstats(8) subcommands are:
28
29       mountstats
30              Display  a  combination  of  per-op  RPC  statistics,  NFS event
31              counts, and NFS byte counts.  This is  the  default  sub-command
32              that will be executed if no sub-command is given.
33
34       iostat Display iostat-like statistics.
35
36       nfsstat
37              Display nfsstat-like statistics.

OPTIONS

40   Options valid for all sub-commands
41       -h, --help
42              show the help message and exit
43
44       -v, --version
45              show program's version number and exit
46
47       -f infile, --file infile
48              Read stats from infile instead of /proc/self/mountstats.  infile
49              must be in the same format as /proc/self/mountstats.   This  may
50              be used with the -S|--since options to display the delta between
51              two different points in time.  This may not  be  used  with  the
52              interval or count options of the iostat sub-command.
53
54       -S sincefile, --since sincefile
55              Show  difference  between  current stats and those in sincefile.
56              sincefile must be in the same format  as  /proc/self/mountstats.
57              This may be used with the -f|--file options to display the delta
58              between two different points in time.  This may not be used with
59              the interval or count options of the iostat sub-command.
60
61   Options specific to the mountstats sub-command
62       -n, --nfs Display only the NFS statistics
63
64       -r, --rpc
65              Display only the RPC statistics
66
67       -R, --raw
68              Display  only the raw statistics.  This is intended for use with
69              the -f|--file and -S|--since options.
70
71       -x, --xprt
72              Display only the transport statistics
73
74   Options specific to the iostat sub-command
75       interval
76              Specifies the amount of time in  seconds  between  each  report.
77              The  first  report  contains  statistics for the time since each
78              file system was mounted.  Each subsequent report  contains  sta‐
79              tistics collected during the interval since the previous report.
80              This may not be used with the -f|--file or -S|--since options.
81
82       count  Determines the number of reports generated at  interval  seconds
83              apart.  If the interval parameter is specified without the count
84              parameter, the command generates reports continuously.  This may
85              not be used with the -f|--file or -S|--since options.
86
87   Options specific to the nfsstat sub-command
88       -3     Show only NFS version 3 statistics.  The default is to show both
89              version 3 and version 4 statistics.
90
91       -4     Show only NFS version 4 statistics.  The default is to show both
92              version 3 and version 4 statistics.
