cifsiostat


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.


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.
