Parameters
all
Optional. Specifies to show the full set of performance metrics. If this parameter is omitted, the default set of
performance metrics will be shown.
count number-of-data-samples
Optional. Specifies the number of data samples to display, from 1 to 100. Each sample will be shown as a
separate row in the command output. If this parameter is omitted, 100 samples will be shown. If you specify
this parameter, do not specify the time-range parameter.
historical
Optional. Specifies to show historical statistics. If this parameter is omitted, live statistics will be shown.
[time-range "date/time-range"]
Optional. Specifies the date/time range of historical statistics to show, in the format "start yyyy-mm-dd
hh : mm[AM| PM] end yyyy-mm-dd hh : mm[AM|PM]". If the start date/time is specified but no
end date/time is specified, the current date/time will be used as the end date/time. The system will return
the oldest sample taken after the start time and the latest sample taken before the end time. If the specified
start date/time is earlier than the oldest sample, that sample will be used as the start date/time. If you
specify this parameter, do not specify the count parameter. If this parameter is omitted, the most recent 100
data samples will be displayed.
vdisk
Specifies the name or serial number of one disk group for which to show historical statistics. A name that
includes a space must be enclosed in double quotes.
vdisks
Optional. Specifies a comma-separated list of the names or serial number of disk groups for which to show
live statistics. A name that includes a space must be enclosed in double quotes. If this parameter is omitted,
statistics will be shown for all disk groups.
Output
Live
Name
The name of the disk group.
Serial Number
The serial number of the disk group.
Bps
The data transfer rate, in bytes per second, calculated over the interval since these statistics were last
requested or reset. This value will be zero if it has not been requested or reset since a controller restart.
IOPS
The input/output operations per second, calculated over the interval since these statistics were last
requested or reset. This value will be zero if it has not been requested or reset since a controller restart.
Reads
The number of read operations since these statistics were last reset or since the controller was restarted.
Writes
The number of write operations since these statistics were last reset or since the controller was restarted.
Data Read
Amount of data read since these statistics were last reset or since the controller was restarted.
Data Written
The amount of data written since these statistics were last reset or since the controller was restarted
I/O Resp Time
The average response time in microseconds for read and write operations, calculated over the interval since
these statistics were last requested or reset.
Read Resp Time
