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



NAME
       cifsiostat - Report CIFS statistics.

SYNOPSIS
       cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ 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.

       -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_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 nfsiostat 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.
