The default is to print both server and +client statistics. +.TP +.B \-c, \-\-client +Print only client-side statistics. +.TP +.B \-n, \-\-nfs +Print only NFS statistics. The default is to print both NFS and RPC +information. +.TP +.B \-2 +Print only NFS v2 statistics. The default is to only print information +about the versions of \fBNFS\fR that have non-zero counts. +.TP +.B \-3 +Print only NFS v3 statistics. The default is to only print information +about the versions of \fBNFS\fR that have non-zero counts. +.TP +.B \-4 +Print only NFS v4 statistics. The default is to only print information +about the versions of \fBNFS\fR that have non-zero counts. +.TP +.B \-m, \-\-mounts +Print information about each of the mounted \fBNFS\fR file systems. + +If this option is used, all other options are ignored. +.TP +.B \-r, \-\-rpc +Print only RPC statistics. +.TP +.BI \-o " facility +Display statistics for the specified facility, which must be one of: +.RS +.TP +.B nfs +NFS protocol information, split up by RPC call. +.TP +.B rpc +General RPC information. +.TP +.B net +Network layer statistics, such as the number of received packets, number +of TCP connections, etc. +.TP +.B fh +Usage information on the server's file handle cache, including the +total number of lookups, and the number of hits and misses. +.TP +.B rc +Usage information on the server's request reply cache, including the +total number of lookups, and the number of hits and misses. +.TP +.B io +Usage information on the server's io statistics; bytes read and +written. +.TP +.B ra +Usage information on the server's read ahead cache, including the +ra cache size, the depth of ra cache hits, and ra cache misses. +.TP +.B all +Display all of the above facilities. +.RE +.TP +.B \-v, \-\-verbose +This is equivalent to \fB\-o all\fR. +.TP +.B \-l, \-\-list +Print information in list form. +.TP +.BI "\-S, \-\-since " file +Instead of printing current statistics, +.B nfsstat +imports statistics from +.I file +and displays the difference between those and the current statistics. +Valid input +.IR file "s may be in the form of " +.B /proc/net/rpc/nfs +(raw client stats), +.B /proc/net/rpc/nfsd +(raw server stats), or saved output from +.B nfsstat +itself (client and/or server stats). Any statistics missing from a saved +.B nfsstat +output +.I file +are treated as zeroes. +.TP +.B \-Z[interval], \-\-sleep=[interval] +Instead of printing current statistics and immediately exiting, +.B nfsstat +takes a snapshot of the current statistics and pauses until it receives +.B SIGINT +(typically from +.BR Ctrl-C ), +at which point it takes another snapshot and displays the difference +between the two. +If \fIinterval\fR is specified, +.B nfsstat +will print the number of \fBNFS\fR calls made since the previous report. +Stats will be printed repeatedly every \fIinterval\fR seconds. +.\" --------------------- EXAMPLES ------------------------------- +.SH EXAMPLES +.TP +.B nfsstat \-o all \-234 +Show all information about all versions of \fBNFS\fR. +.TP +.B nfsstat \-\-verbose \-234 +Same as above. +.TP +.B nfsstat \-o all +Show all information about active versions of \fBNFS\fR. +.TP +.B nfsstat \-\-nfs \-\-server \-3 +Show statistics for \fBNFS\fR version 3 server. +.TP +.B nfsstat \-m +Show information about mounted \fBNFS\fR filesystems. +.\" --------------------- DISPLAY -------------------------------- +.SH DISPLAY +The \fBFlags\fR output from the \fB\-m\fR option is the same as the +flags give to the \fBmount\fR command. +.\" --------------------- FILES ---------------------------------- +.SH FILES +.TP +.B /proc/net/rpc/nfsd +.BR procfs -based +interface to kernel NFS server statistics. +.TP +.B /proc/net/rpc/nfs +.BR procfs -based +interface to kernel NFS client statistics. +.TP +.B /proc/mounts +.BR procfs -based +interface to the mounted filesystems. +.\" -------------------- SEE ALSO -------------------------------- +.SH SEE ALSO +.BR rpc.nfsd (8). +.BR nfs (5). +.\" ---------------------- BUGS ---------------------------------- +.SH BUGS +The default output has been changed.

The \fB\-v\fR does what the \fB\-a\fR option used to do, +and the new \fB\-[234]\fR options replace the \fB\-v\fR option. +.P +The \fBDisplay\fR section should be more complete. +.P +Further bugs can be found or reported at +.BR http://nfs.sf.net/ . +.\" -------------------- AUTHOR ---------------------------------- +.SH AUTHOR +Olaf Kirch, -- cgit v1.2.3
