       cifsiostat - Report CIFS statistics.


       cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ --dec={ 0 | 1 | 2 } ] [ --human ] [ --pretty
       ] [ interval [ count ] ]


       The cifsiostat command displays  statistics  about  read  and  write  operations  on  CIFS

       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


       The  CIFS  report  provides statistics for each mounted CIFS filesystem.  The report shows
       the following fields:

              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

       wop/s  Indicate  the  number  of 'write' operations that were issued to the filesystem per

       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.


       --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.

              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     Display statistics in kilobytes per second.

       -m     Display statistics in megabytes per second.

              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.


       The cifsiostat command takes into account the following environment variables:

              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
              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.

              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.

              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.

       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.


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