Monitoring Server Power Consumption

Oracle ILOM provides the following power metrics for the server:

• Power Supply Maximum – The maximum amount of power the power supply units (PSU) can draw.

• Allocated Power – The power allocated for installed and hot-pluggable components.

• Actual Power – The amount of power the server is currently consuming.

• Peak Permitted – The maximum power the server can consume at any time.

In addition, you can view historical power consumption data from the Oracle ILOM web interface.

To view server power metrics, see the following procedures:

• View Current Server Power Consumption (Oracle ILOM)

• View Power Allocated to Server Components (Oracle ILOM)

• View Historical Power Consumption Data (Oracle ILOM)

View Current Server Power Consumption (Oracle ILOM)

1. To view current server power consumption in the Oracle ILOM web interface:
   1. Log in to the Oracle ILOM web interface.
   2. In the navigation pane, click Power Management → Consumption.
   3. On the Power Consumption page, review the Actual Power property.
2. To view current server power consumption in the Oracle ILOM command-line interface (CLI):
   1. Log in to the Oracle ILOM CLI.
   2. Type: show /System/Power
   3. Review the actual_power_consumption property.

   For details, refer to Monitoring Power Consumption, Oracle ILOM User's Guide for System Monitoring and Diagnostics, Firmware Release 5.0 at Systems Management Documentation.

View Power Allocated to Server Components (Oracle ILOM)

1. To view the power allocated to server components in the Oracle ILOM web interface:
   1. Log in to the Oracle ILOM web interface.
   2. In the navigation pane, click Power Management → Allocation.
   3. On the Power Allocation page, review the Per Component Power Map.
2. To view the power allocated to server components in the Oracle ILOM command-line interface (CLI):
   1. Log in to the Oracle ILOM CLI.
   2. Type the following command:

      -> show /SP/powermgmt/powerconf/component

      Where component is one of the following: Fans, PSUs, CPUs, memory, IO, or MB.

   3. Review the allocated_power property.

   For details, refer to Monitoring Power Allocations, Oracle ILOM User's Guide for System Monitoring and Diagnostics, Firmware Release 5.0 at Systems Management Documentation.

View Historical Power Consumption Data (Oracle ILOM)

In the Oracle ILOM web interface, you can view the average power consumption for each minute of the last hour or for each hour of the last 14 days. Historical power consumption data is not viewable from the Oracle ILOM command-line interface.

1. Log in to the Oracle ILOM web interface.
2. In the navigation pane, click Power Management → History.
3. Review the Power History table.

   For details, refer to Analyzing Power Usage Statistics, Oracle ILOM Administrator's Guide for Configuration and Maintenance, Firmware Release 5.0 at Systems Management Documentation.
