NAME
cifsiostat - Report CIFS statistics.
SYNOPSIS
cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ 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 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.
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
-h Make the CIFS 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 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=33;1:Z=33;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.
BUG
/proc filesystem must be mounted for cifsiostat to work.
FILE
/proc/fs/cifs/Stats contains CIFS statistics.
