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 con‐ sists 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 gener‐ ated at _interval_ seconds apart. If the _interval_ parameter is specified without the _count_ pa‐ rameter, 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 sec‐ ond. wop/s Indicate the number of 'write' operations that were issued to the filesystem per sec‐ ond. 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 --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. kilobytes, sectors...) associated with the metrics. ### -k ### -m ### --pretty Make the CIFS report easier to read by a human. ### -t of the **S**___**TIME**___**FORMAT** environment variable (see below). ### -V ## 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 termi‐ nal. 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 in‐ dicates 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** speaks of 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. ## AUTHORS Written by Ivana Varekova (varekova redhat.com) Maintained by Sebastien Godard (sysstat orange.fr) ## SEE ALSO [**sar**(1)](https://www.chedong.com/phpMan.php/man/sar/1/markdown), [**pidstat**(1)](https://www.chedong.com/phpMan.php/man/pidstat/1/markdown), [**mpstat**(1)](https://www.chedong.com/phpMan.php/man/mpstat/1/markdown), [**vmstat**(8)](https://www.chedong.com/phpMan.php/man/vmstat/8/markdown), [**iostat**(1)](https://www.chedong.com/phpMan.php/man/iostat/1/markdown), [**tapestat**(1)](https://www.chedong.com/phpMan.php/man/tapestat/1/markdown), [**nfsiostat**(1)](https://www.chedong.com/phpMan.php/man/nfsiostat/1/markdown) _ _ Linux JULY 2020 [CIFSIOSTAT(1)](https://www.chedong.com/phpMan.php/man/CIFSIOSTAT/1/markdown)
