NAMEcifsiostat - Report CIFS statistics.
SYNOPSIScifsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [--debuginfo] [ interval [ count ] ]
DESCRIPTIONThe 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.
REPORTThe CIFS report provides statistics for each mounted CIFS filesystem. The report shows the following fields:
Filesystem:This columns shows the mountpoint of the CIFS filesystem.
rop/sIndicate the number of 'read' operations that were issued to the filesystem per second.
wop/sIndicate the number of 'write' operations that were issued to the filesystem per second.
fo/sIndicate the number of open files per second.
fc/sIndicate the number of closed files per second.
fd/sIndicate the number of deleted files per second.
--debuginfoPrint debug output to stderr.
-hMake the CIFS report easier to read by a human.
-kDisplay statistics in kilobytes per second.
-mDisplay statistics in megabytes per second.
-tPrint the time for each report displayed. The timestamp format may depend on the value of the S_TIME_FORMAT environment variable (see below).
-VPrint version number then exit.
ENVIRONMENTThe cifsiostat command takes into account the following environment variables:
S_TIME_FORMATIf 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.
