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).
