150 Alphabetical list of commands
show disk-statistics
Description
Shows live or historical performance statistics for disks. For disk performance statistics, the system
samples live data every 15 seconds and historical data every quarter hour, and retains historical
data for 6 months.
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 XML API output are described in
"XML API basetype properties" (page 221)

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

. 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. 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
