NAME
       cifsiostat - Report CIFS statistics.


SYNOPSIS
       cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ -y ] [ --dec={ 0 | 1 | 2
       } ] [ --human ] [ -o JSON ] [ --pretty ] [ 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), unless the -y option is used (in this case, the
       first report is omitted).  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 (kibibytes, mebibytes) read
	      per second.

       wB/s (wkB/s, wMB/s)
	      Indicate the average number of bytes (kibibytes, mebibytes)
	      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     This option is equivalent to specifying --human --pretty.

       --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.  kibibytes, sectors...) associated with the metrics.

       -k     Display statistics in kibibytes per second.

       -m     Display statistics in mebibytes per second.

       -o JSON
	      Display the statistics in JSON (JavaScript Object Notation)
	      format.  JSON output field order is undefined, and new fields
	      may be added in the future.

       --pretty
	      Make the CIFS report easier to read by a human.

       -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.

       -y     Omit first report with statistics since system boot, if
	      displaying multiple records at given interval.


ENVIRONMENT
       The cifsiostat command takes into account the following environment
       variables:

       S_COLORS
	      By default statistics are displayed in color when the output is
	      connected to a terminal.	Use this variable to change the
	      settings. Possible values for this variable are never, always or
	      auto (the latter is equivalent to the default settings).
	      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.


BUG
       /proc filesystem must be mounted for cifsiostat to work.

       Although cifsiostat displays units corresponding to kilobytes (kB),
       megabytes (MB)..., it actually uses kibibytes (kiB), mebibytes (MiB)...
       A kibibyte is equal to 1024 bytes, and a mebibyte is equal to 1024
       kibibytes.


FILE
       /proc/fs/cifs/Stats contains CIFS statistics.
