CIFSIOSTAT(1) Linux User's Manual CIFSIOSTAT(1)
NAME
cifsiostat - Report CIFS statistics.
SYNOPSIS
cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ --dec={ 0 | 1 | 2 } ] [ --human ] [ interval [ count ] ]
DESCRIPTION
The cifsiostat command displays statistics about read and write operations on CIFS 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 pre
vious report. A report consists of a CIFS header row followed by a line of statistics for each CIFS filesystem that is
mounted. The count parameter can be specified in conjunction with the interval parameter. If the count parameter is speci
fied, 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 cifsiostat command generates reports continuously.
REPORT
The CIFS report provides statistics for each mounted CIFS filesystem. The report shows the following fields:
Filesystem:
This columns shows the mount point of the CIFS filesystem.
rB/s (rkB/s, rMB/s)
Indicate the average number of bytes (kilobytes, megabytes) read per second.
wB/s (wkB/s, wMB/s)
Indicate the average number of bytes (kilobytes, megabytes) written per second.
rop/s
Indicate the number of 'read' operations that were issued to the filesystem per second.
wop/s
Indicate the number of 'write' operations that were issued to the filesystem per second.
fo/s
Indicate the number of open files per second.
fc/s
Indicate the number of closed files per second.
fd/s
Indicate the number of deleted files per second.
OPTIONS
--dec={ 0 | 1 | 2 }
Specify the number of decimal places to use (0 to 2, default value is 2).
-h Make the CIFS report easier to read by a human. --human is enabled implicitly with this option.
--human
Print sizes in human readable format (e.g. 1.0k, 1.2M, etc.) The units displayed with this option supersede any other
default units (e.g. kilobytes, sectors...) associated with the metrics.
-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 environ
ment variable (see below).
-V Print version number then exit.
ENVIRONMENT
The cifsiostat command takes into account the following environment variables:
S_COLORS
When this variable is set, display statistics in color on the terminal. Possible values for this variable are never,
always or auto (the latter is the default).
Note: On Debian sysstems the colors are displayed by default when output is connected to the terminal, even if this
variable is not set (i.e. unset variable is treated as if it were set to auto).
Please note that the color (being red, yellow, or some other color) used to display a value is not indicative of any
kind of issue simply because of the color. It only indicates different ranges of values.
S_COLORS_SGR
Specify the colors and other attributes used to display statistics on the terminal. Its value is a colon-separated
list of capabilities that defaults to I=32;22:N=34;1:Z=34;22. Supported capabilities are:
I= SGR substring for filesystem names.
N= SGR substring for non-zero statistics values.
Z= SGR substring for zero values.
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 re
port header. The cifsiostat command will use the ISO 8601 format (YYYY-MM-DD) instead. The timestamp displayed with
option -t will also be compliant with ISO 8601 format.
BUG
/proc filesystem must be mounted for cifsiostat to work.
FILE
/proc/fs/cifs/Stats contains CIFS statistics.
