nfsiostat
NFSIOSTAT(1) Linux User's Manual NFSIOSTAT(1)NAME
nfsiostat - Report input/output statistics for network filesystems (NFS).
SYNOPSIS
nfsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ interval [ count ] ]
DESCRIPTION
The nfsiostat command displays statistics about read and write operations on NFS filesystems.
The interval parameter specifies the amount of time in seconds between each report. The first report contains statistics for the time since
system startup (boot). Each subsequent report contains statistics collected during the interval since the previous report. A report con-
sists of an NFS header row followed by a line of statistics for each network filesystem that is mounted. The count parameter can be speci-
fied in conjunction with the interval parameter. If the count parameter is specified, the value of count determines the number of reports
generated at interval seconds apart. If the interval parameter is specified without the count parameter, the nfsiostat command generates
reports continuously.
REPORT
The Network Filesystem (NFS) report provides statistics for each mounted network filesystem. Transfer rates are shown in 1K blocks by
default, unless the environment variable POSIXLY_CORRECT is set, in which case 512-byte blocks are used. The report shows the following
fields:
Filesystem:
This columns shows the hostname of the NFS server followed by a colon and by the directory name where the network filesystem is
mounted.
rBlk_nor/s (rkB_nor/s, rMB_nor)
Indicate the number of blocks (kilobytes, megabytes) read by applications via the read(2) system call interface. A block has a size
of 512 bytes.
wBlk_nor/s (wkB_nor/s, wMB_nor/s)
Indicate the number of blocks (kilobytes, megabytes) written by applications via the write(2) system call interface.
rBlk_dir/s (rkB_dir/s, rMB_dir/s)
Indicate the number of blocks (kilobytes, megabytes) read from files opened with the O_DIRECT flag.
wBlk_dir/s (wkB_dir/s, wMB_dir/s)
Indicate the number of blocks (kilobytes, megabytes) written to files opened with the O_DIRECT flag.
rBlk_svr/s (rkB_svr/s, rMB_svr/s)
Indicate the number of blocks (kilobytes, megabytes) read from the server by the NFS client via an NFS READ request.
wBlk_svr/s (wkB_svr/s, wMB_svr/s)
Indicate the number of blocks (kilobytes, megabytes) written to the server by the NFS client via an NFS WRITE request.
ops/s
Indicate the number of operations that were issued to the filesystem per second.
rops/s
Indicate the number of 'read' operations that were issued to the filesystem per second.
wops/s
Indicate the number of 'write' operations that were issued to the filesystem per second.
OPTIONS -h Make the NFS report easier to read by a human.
-k Display statistics in kilobytes per second.
-m Display statistics in megabytes per second.
-t Print the time for each report displayed. The timestamp format may depend on the value of the S_TIME_FORMAT environment variable
(see below).
-V Print version number then exit.
ENVIRONMENT
The nfsiostat command takes into account the following environment variables:
S_TIME_FORMAT
If this variable exists and its value is ISO then the current locale will be ignored when printing the date in the report header.
The nfsiostat command will use the ISO 8601 format (YYYY-MM-DD) instead. The timestamp displayed with option -t will also be com-
pliant with ISO 8601 format.
POSIXLY_CORRECT
When this variable is set, transfer rates are shown in 512-byte blocks instead of the default 1K blocks.
BUG
/proc filesystem must be mounted for nfsiostat to work.
FILE
/proc/self/mountstats contains statistics for network filesystems.
