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

NAME         top

       cifsiostat - Report CIFS statistics.

SYNOPSIS         top

       cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ --human ] [ interval [
       count ] ]

DESCRIPTION         top

       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 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         top

       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 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         top

       -h     Make the CIFS report easier to read by a human.  --human is
              enabled implicitly with this option.
       --human
              Print sizes in human readable format (e.g. 1k, 1.23M, 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 environment
              variable (see below).
       -V     Print version number then exit.

ENVIRONMENT         top

       The cifsiostat command takes into account the following environment
       variables:
       S_COLORS
              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).
              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         top

       /proc filesystem must be mounted for cifsiostat to work.

FILE         top

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