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 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 speci-
       fied 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 variable (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.
