Show Disk-Statistics - HP P2000 G3 Cli Reference Manual

show disk-statistics

Description Shows live or historical performance statistics for disks. You can view live statistics for all or specified
disks, or historical statistics for a specified disk. The system samples disk-performance statistics every
quarter hour and retains performance data for 30 days only.
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.
Properties shown only in XML API format are described in
page 345.
Syntax To show live statistics:
show disk-statistics [disks]
To show historical statistics:
show disk-statistics
disk
historical
[time-range "date/time-range"]
[count number-of-data-samples]
[all]
Parameters disks
Optional. Identifies one or more disks to show live statistics for. If this parameter is omitted, statistics
will be shown for all disks. For disk syntax, see
disk
Identifies one disk to show historical statistics for. For disk syntax, see
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.
count number-of-data-samples
Optional. Specifies the number of data samples to display, from 1–100. 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.
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.
Output
Durable ID
(Live)
Disk ID in the form disk_enclosure-number.disk-number.
Serial Number
Disk serial number.
Bytes per second
Data transfer rate 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.
