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 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

       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 variable (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 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.

FILE

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