48 command displays statistics kept about
50 client and server activity.
51 For the NFSv4 server, the statistics are for operations within the Compound
52 RPCs and not the count of RPCs.
53 If you wish to compare RPC counts between NFSv3 and NFSv4, you must use
54 statistics in the client(s).
56 The options are as follows:
57 .Bl -tag -width indent
59 Only display client side statistics.
61 Display statistics for the new NFS server that are similar to those
64 This includes kilobytes per transfer, transfers per second, and megabytes per
65 second for read, write, and all operations.
66 It also includes the current queue depth, the busy percentage, and latency
70 flag is added, commits per second, commit latency, read latency, and write
71 latency are also added to the display.
72 The busy percentage shown can exceed 100 at times.
73 This is because of the way busy percentages are calculated.
74 The busy time is calculated by adding the elapsed time between the
75 last time an operation started or finished,
77 If there is only one operation outstanding, the "busy time" time
78 will get updated with the total time of that operation.
79 That means that the difference in the busy time between the two
80 measurement intervals (often 1 second)
81 will increase by more than the measurement interval.
83 Report the extra statistics collected by the NFS client and
88 except that the statistics include NFSv4.1 and the numbers aren't clipped
96 Extract values associated with the name list from the specified core
97 instead of the default
100 Report the mount options for all new NFS client mounts.
101 This option overrides all others and
103 will exit after completing the report.
104 This option is only supported by the new NFS client.
106 Extract the name list from the specified system instead of the default
107 .Pa /boot/kernel/kernel .
109 Only display server side statistics.
111 Use wide format with interval short summary.
112 This option is especially
113 useful when combined with
120 Display a shorter summary of
122 activity for both the client and server at
