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  dur-
       ing  the  interval  since  the  previous report.  A report consists of an 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  parame-
       ter, 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
              The number of open files per second.

       fc/s
              The number of closed files per second.

       fd/s
              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.


BUGS
       /proc filesystem must be mounted for cifsiostat to work.


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