NAME

6       cifsiostat - Report CIFS statistics.
7

SYNOPSIS

9       cifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ interval [ count ] ]
10

DESCRIPTION

12       The  cifsiostat command displays statistics about read and write opera‐
13       tions on CIFS filesystems.
14
15       The interval parameter specifies the amount of time in seconds  between
16       each  report.  The  first report contains statistics for the time since
17       system startup (boot). Each subsequent report contains statistics  col‐
18       lected  during  the  interval since the previous report.  A report con‐
19       sists of a CIFS header row followed by a line of  statistics  for  each
20       CIFS  filesystem that is mounted.  The count parameter can be specified
21       in conjunction with the interval parameter. If the count  parameter  is
22       specified,  the  value of count determines the number of reports gener‐
23       ated at interval seconds apart. If the interval parameter is  specified
24       without  the  count parameter, the cifsiostat command generates reports
25       continuously.

REPORT

29       The CIFS report provides statistics for each mounted  CIFS  filesystem.
30       The report shows the following fields:
31
32       Filesystem:
33              This columns shows the mount point of the CIFS filesystem.
34
35       rB/s (rkB/s, rMB/s)
36              Indicate the average number of bytes (kilobytes, megabytes) read
37              per second.
38
39       wB/s (wkB/s, wMB/s)
40              Indicate the average  number  of  bytes  (kilobytes,  megabytes)
41              written per second.
42
43       rop/s
44              Indicate the number of 'read' operations that were issued to the
45              filesystem per second.
46
47       wop/s
48              Indicate the number of 'write' operations that  were  issued  to
49              the filesystem per second.
50
51       fo/s
52              Indicate the number of open files per second.
53
54       fc/s
55              Indicate the number of closed files per second.
56
57       fd/s
58              Indicate the number of deleted files per second.

OPTIONS

61       -h     Make the CIFS report easier to read by a human.
62
63       -k     Display statistics in kilobytes per second.
64
65       -m     Display statistics in megabytes per second.
66
67       -t     Print  the  time for each report displayed. The timestamp format
68              may depend on the value of the S_TIME_FORMAT  environment  vari‐
69              able (see below).
70
71       -V     Print version number then exit.
72
73

ENVIRONMENT

75       The  cifsiostat  command  takes  into account the following environment
76       variables:
77
78
79       S_TIME_FORMAT
80              If this variable exists and its value is ISO  then  the  current
81              locale  will  be  ignored  when  printing the date in the report
82              header. The nfsiostat command  will  use  the  ISO  8601  format
83              (YYYY-MM-DD)  instead.   The  timestamp displayed with option -t
84              will also be compliant with ISO 8601 format.
85
86

BUG

88       /proc filesystem must be mounted for cifsiostat to work.
89
90

FILE

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