ldmpower [-ehiprstvx | -o hours | -m minutes] [-c resource] [-l ldom[,ldom[,...]]] [interval [count]]
The ldmpower command shows the power-consumption data in watts for domains. By default, it shows the processor power that is consumed by each running domain. You can use options to view memory power consumption and the power consumption of the entire system divided among the running domains. The per-domain system power consumption is extrapolated from the per-domain processor and memory power consumption.
When specified with no options, the ldmpower command shows the average power consumption during the last 15, 30, and 60 seconds. The command can also show the most recent power-consumption data. For a longer history, the command can show up to 60 one-minute averages covering the last hour and 336 one-hour averages covering the last 14 days.
To run this command as a non-privileged user, you must be assigned the LDoms Power Mgmt Observability rights profile. If you already have been assigned the LDoms Management or LDoms Review rights profile, you automatically have permission to run the ldmpower command.
This command is not supported on UltraSPARC T2, UltraSPARC T2 Plus, and Fujitsu M10 platform.
The ldmpower command uses the following options and operands:
Shows per-domain power consumption for the specified resource type, resource. Valid values are processors and memory. The long version of this option is –-component.
Shows the minimum and maximum power-consumption values since data recording began. The long version of this option is –-extremes.
Shows descriptions of the ldmpower command options. The alternate short version of this option is –? and the long version of this option is –-help.
Shows instantaneous power-consumption data. The long versions of this option are –-instant and –-instantaneous.
Shows power-consumption data for one or more specified domains. Domain names are separated by commas. The long version of this option is –-list.
Note that less data is shown for domains that have been booted for a shorter amount of time than the requested period.
Shows up to one hour of average power-consumption data in fixed one-minute intervals. The long version of this option is –-minutes.
Note that less data is shown if the Logical Domains daemon has been running for a shorter amount of time than the requested period.
Shows up to 14 days of average power-consumption data in fixed one-hour intervals. The long version of this option is –-hours.
Note that less data is shown if the Logical Domains daemon has been running for a shorter amount of time than the requested period.

Suppresses the output header. The long version of this option is –-suppress.
Shows time stamps in the output. The long version of this option is –-timestamps.
Shows version data. The long version of this option is –-version.
Shows extrapolated power-consumption averages. These averages reflect the percentage of overall system watts that are being consumed per domain. The per-domain system power consumption is extrapolated from the per-domain processor and memory power consumption. This option can be used with any of the –o, –i, –m, and –r options. The long version of this option is –-extrapolate.
Reports output once each interval seconds.
