CLI Guide

The historical option allows you to specify a time range or a number (count) of data samples to include. It is
not recommended to specify both the time-range and count parameters. If both parameters are specified,
and more samples exist for the specified time range, the samples' values will be aggregated to show the
required number of samples.
Statistics shown only in API output are described in API basetype properties.

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.
error-stats
Optional. Specifies to show live error statistics for all disks or specified disks. If you specify this parameter, do
not specify the all, count, historical, or time-range parameters.
filename filename.csv
Optional. Specifies to save historical statistics, in CSV format, to a file on the controller. To access the file,
use SFTP or FTP.
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.
disks
Optional for live statistics. Required for historical statistics. Specifies a comma-separated list of disks for
which to show information. If this parameter is omitted, information will be shown for all disks. For disk
syntax, see Command syntax
Output
