CIFSIOSTAT(1) Linux User's Manual CIFSIOSTAT(1)
cifsiostat - Report CIFS statistics.
cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ --human ] [ interval [
count ] ]
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 previous 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 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 cifsiostat command generates reports continuously.
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.
-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. 1k, 1.23M, 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 environment
variable (see below).
-V Print version number then exit.
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).
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 report
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.
/proc filesystem must be mounted for cifsiostat to work.
/proc/fs/cifs/Stats contains CIFS statistics.
