CIFSIOSTAT(1)					     Linux User's Manual				       CIFSIOSTAT(1)

NAME
       cifsiostat - Report CIFS statistics.

SYNOPSIS
       cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ -y ] [ --dec={ 0 | 1 | 2 } ] [ --human ] [ -o JSON ] [ --pretty ] [ in‐
       terval [ 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 statis‐
       tics  for the time since system startup (boot), unless the -y option is used (in this case, the first report is omit‐
       ted).  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-sep‐
	      arated 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.
