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

NAME
       cifsiostat - Report CIFS statistics.

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

DESCRIPTION
       The cifsiostat command displays statistics about read and write  opera-
       tions 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 col-
       lected 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 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 (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
       -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  vari-
              able (see below).

       -V     Print version number then exit.

ENVIRONMENT
       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 statis-
              tics 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.

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