22 21 .LP
23 22 \fBnfsstat\fR displays statistical information about the \fBNFS\fR and
24 23 \fBRPC\fR (Remote Procedure Call), interfaces to the kernel. It can also be
25 24 used to reinitialize this information. If no options are given the default is
26 25 as follows:
27 26 .sp
28 27 .LP
29 28 \fBnfsstat\fR \fB-csnra\fR
30 29 .sp
31 30 .LP
32 31 The default displays everything, but reinitializes nothing.

52 50 \fBNFS_ACL\fR information is printed. Can be combined with the \fB-n\fR,
53 51 \fB-r\fR, and \fB-a\fR options to print client side \fBNFS\fR, \fBRPC\fR, and
54 52 \fBNFS_ACL\fR information only.

64 62 Display statistics for each \fBNFS\fR mounted file system. If \fIpathname\fR is
65 63 not specified, displays statistics for all NFS mounted file systems. If
66 64 \fIpathname\fR is specified, displays statistics for the NFS mounted file
67 65 systems indicated by \fIpathname\fR.
68 66 .sp
69 67 This includes the server name and address, mount flags, current read and write
70 68 sizes, the retransmission count, the attribute cache timeout values, failover
71 69 information, and the timers used for dynamic retransmission. The dynamic
72 70 retransmission timers are displayed only where dynamic retransmission is in
73 71 use. By default, \fBNFS\fR mounts over the \fBTCP\fR protocols and \fBNFS\fR
74 72 Version 3 mounts over either \fBTCP\fR or \fBUDP\fR do not use dynamic
75 73 retransmission.
76 74 .sp
77 75 If you specify the \fB-m\fR option, this is the only option that \fBnfsstat\fR
78 76 uses. If you specify other options with \fB-m\fR, you receive an error message
79 77 alerting that the \fB-m\fR flag cannot be combined with other options.
