NAME

       cifsiostat - Report CIFS statistics.

SYNOPSIS

       cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ --human ] [ 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
       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.  --human is enabled implicitly with this option.

       --human
              Print  sizes in human readable format (e.g. 1k, 1.23M, etc.)  The units displayed with this option
              supersede any other default units (e.g.  kilobytes, sectors...) associated with the metrics.

       -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_COLORS
              When  this variable is set, display statistics in color on the terminal.  Possible values for this
              variable are never, always or auto (the latter is the default).

              Please note that the color (being red, yellow, or some other color) used to display a value is not
              indicative of any kind of issue simply because of the color. It only indicates different ranges of
              values.

       S_COLORS_SGR
              Specify the colors and other attributes used to display statistics on the terminal.  Its value  is
              a  colon-separated  list  of  capabilities  that  defaults  to  I=32;22:N=34;1:Z=34;22.  Supported
              capabilities are:

              I=     SGR substring for filesystem names.

              N=     SGR substring for non-zero statistics values.

              Z=     SGR substring for zero values.

       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 cifsiostat 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.
