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  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  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  com-
              pliant with ISO 8601 format.

BUG

       /proc filesystem must be mounted for cifsiostat to work.

FILE

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