Ubuntu Manpage: cifsiostat - Report CIFS statistics.

NAME

       cifsiostat - Report CIFS statistics.

SYNOPSIS

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

       --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.

       --human
              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.

       --pretty
              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.

ENVIRONMENT

The cifsiostat command takes into account the following environment variables:

S_COLORS
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
settings).
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.

       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.

FILE

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