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

       cifsiostat - Report CIFS statistics.

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

       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 pre

       vious  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  speci

       fied,  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.

       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.

              Indicate the number of 'read' operations that were issued to the filesystem per second.

              Indicate the number of 'write' operations that were issued to the filesystem per second.

              Indicate the number of open files per second.

              Indicate the number of closed files per second.

              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     Make the CIFS report easier to read by a human.  --human is enabled implicitly with this option.

              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.

       -t     Print  the  time for each report displayed. The timestamp format may depend on the value of the S_TIME_FORMAT environ

              ment variable (see below).

       -V     Print version number then exit.

       The cifsiostat command takes into account the following environment variables:

              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).

              Note:  On  Debian  sysstems the colors are displayed by default when output is connected to the terminal, even if this
              variable is not set (i.e. unset variable is treated as if it were set to auto).

              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 re

              port  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.

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