Имя (Name)
cifsiostat - Report CIFS statistics.
Синопсис (Synopsis)
cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ --dec={ 0 | 1 | 2 }
] [ --human ] [ --pretty ] [ interval [ count ] ]
Описание (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.
Отчет (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.
Параметры (Options)
--dec={ 0 | 1 | 2 }
Specify the number of decimal places to use (0 to 2,
default value is 2).
-h This option is equivalent to specifying --human --pretty.
--human
Print sizes in human readable format (e.g. 1.0k, 1.2M,
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.
--pretty
Make the CIFS report easier to read by a human.
-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.
Окружение (Environment)
The cifsiostat command takes into account the following
environment variables:
S_COLORS
By default statistics are displayed in color when the
output is connected to a terminal. Use this variable to
change the settings. Possible values for this variable are
never, always or auto (the latter is equivalent to the
default settings).
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.
Although cifsiostat speaks of kilobytes (kB), megabytes (MB)...,
it actually uses kibibytes (kiB), mebibytes (MiB)... A kibibyte
is equal to 1024 bytes, and a mebibyte is equal to 1024
kibibytes.
