nfsstat - list NFS statistics
nfsstat [OPTION]...
The
nfsstat displays statistics kept about NFS client and server activity.
- -s,
--server
- Print only server-side statistics. The default is to print both server
and client statistics.
- -c, --client
- Print only client-side statistics.
- -n, --nfs
- Print only NFS statistics. The default is to print both NFS and RPC information.
- -2
- Print only NFS v2 statistics. The default is to only print information
about the versions of NFS that have non-zero counts.
- -3
- Print only NFS v3
statistics. The default is to only print information about the versions
of NFS that have non-zero counts.
- -4
- Print only NFS v4 statistics. The default
is to only print information about the versions of NFS that have non-zero
counts.
- -m, --mounts
- Print information about each of the mounted NFS file systems.
If this option is used, all other options are ignored.
- -r, --rpc
- Print only
RPC statistics.
- -o facility
- Display statistics for the specified facility,
which must be one of:
- nfs
- NFS protocol information, split up by RPC call.
- rpc
- General RPC information.
- net
- Network layer statistics, such as the number
of received packets, number of TCP connections, etc.
- fh
- Usage information
on the server’s file handle cache, including the total number of lookups,
and the number of hits and misses.
- rc
- Usage information on the server’s request
reply cache, including the total number of lookups, and the number of hits
and misses.
- all
- Display all of the above facilities.
- -v, --verbose
- This is equivalent
to -o all.
- -l, --list
- Print information in list form.
- -S, --since file
- Instead of
printing current statistics, nfsstat imports statistics from file and
displays the difference between those and the current statistics. Valid
input files may be in the form of /proc/net/rpc/nfs (raw client stats),
/proc/net/rpc/nfsd (raw server stats), or saved output from nfsstat itself
(client and/or server stats). Any statistics missing from a saved nfsstat
output file are treated as zeroes.
- -Z[interval], --sleep=[interval]
- Instead
of printing current statistics and immediately exiting, nfsstat takes a
snapshot of the current statistics and pauses until it receives SIGINT
(typically from Ctrl-C), at which point it takes another snapshot and displays
the difference between the two. If interval is specified, nfsstat will
print the number of NFS calls made since the previous report. Stats will
be printed repeatedly every interval seconds.
- nfsstat -o all -234
- Show all information about all versions of NFS.
- nfsstat --verbose -234
- Same
as above.
- nfsstat -o all
- Show all information about active versions of NFS.
- nfsstat --nfs --server -3
- Show statistics for NFS version 3 server.
- nfsstat -m
- Show information about mounted NFS filesystems.
The Flags output
from the -m option is the same as the flags give to the mount command.
- /proc/net/rpc/nfsd
- procfs-based interface to kernel NFS server statistics.
- /proc/net/rpc/nfs
- procfs-based interface to kernel NFS client statistics.
- /proc/mounts
- procfs-based
interface to the mounted filesystems.
rpc.nfsd(8)
. nfs(5)
.
The
default output has been changed. To get the old default output you must
run nfsstat --auto -2.
The function of the -v and -a options have changed. The
-a option is now reserved for future use. The -v does what the -a option used
to do, and the new -[234] options replace the -v option.
The Display section
should be more complete.
Further bugs can be found or reported at http://nfs.sf.net/.
