5 5 NAME
6 6 nfsstat - NFS statistics
7 7
8 8 SYNOPSIS
9 9 nfsstat [-cnrsza] [-T u | d ] [-v version] [interval [count]]
10 10
11 11
12 12 nfsstat -m [pathname]...
13 13
14 14
15 15 DESCRIPTION
16 16 nfsstat displays statistical information about the NFS and RPC (Remote
17 17 Procedure Call), interfaces to the kernel. It can also be used to
18 18 reinitialize this information. If no options are given the default is
19 19 as follows:
20 20
21 21
22 22 nfsstat -csnra
23 23
24 24
25 25 The default displays everything, but reinitializes nothing.
26 26
27 27 OPTIONS
28 28 -a
29 29
30 30 Display NFS_ACL information.
31 31
32 32
33 33 -c
34 34
35 35 Display client information. Only the client side NFS, RPC, and
36 36 NFS_ACL information is printed. Can be combined with the -n, -r,
37 37 and -a options to print client side NFS, RPC, and NFS_ACL
38 38 information only.
39 39
40 40
41 41 -m [pathname...]
42 42
43 43 Display statistics for each NFS mounted file system. If pathname is
44 44 not specified, displays statistics for all NFS mounted file
45 45 systems. If pathname is specified, displays statistics for the NFS
46 46 mounted file systems indicated by pathname.
47 47
48 48 This includes the server name and address, mount flags, current
49 49 read and write sizes, the retransmission count, the attribute cache
50 50 timeout values, failover information, and the timers used for
51 51 dynamic retransmission. The dynamic retransmission timers are
52 52 displayed only where dynamic retransmission is in use. By default,
53 53 NFS mounts over the TCP protocols and NFS Version 3 mounts over
54 54 either TCP or UDP do not use dynamic retransmission.
55 55
56 56 If you specify the -m option, this is the only option that nfsstat
57 57 uses. If you specify other options with -m, you receive an error
58 58 message alerting that the -m flag cannot be combined with other
59 59 options.
60 60
61 61
62 62 -n
63 63
64 64 Display NFS information. NFS information for both the client and
65 65 server side are printed. Can be combined with the -c and -s options
66 66 to print client or server NFS information only.
67 67
68 68
69 69 -r
70 70
71 71 Display RPC information.
72 72
73 73
74 74 -s
75 75
76 76 Display server information.
77 77
78 78
79 79 -T u | d
80 80
81 81 Display a time stamp.
82 82
83 83 Specify u for a printed representation of the internal
84 84 representation of time. See time(2). Specify d for standard date
85 85 format. See date(1).
86 86
87 87
88 88 -v version
89 89
90 90 Specify which NFS version for which to print statistics. When
91 91 followed by the optional version argument, (2|3|4), specifies
92 92 statistics for that version. By default, prints statistics for all
93 93 versions.
94 94
95 95
96 96 -z
97 97
98 98 Zero (reinitialize) statistics. This option is for use by the super
99 99 user only, and can be combined with any of the above options to
100 100 zero particular sets of statistics after printing them.
