|||
Note - Power consumption history is provided using the ILOM CLI and web interfaces. This information is not available through IPMI or SNMP. |
Monitor Total System Power Consumption |
1. Log in to the ILOM SP CLI or the ILOM CMM CLI.
2. Type the show command to display the total power consumption.
The following table lists and describes the properties of the Total Power Consumption sensor for CLI.
Threshold values are platform specific. Refer to your platform documentation for details. |
|
Monitor Actual Power Consumption |
1. Log in to the ILOM server SP CLI or ILOM CMM CLI.
2. Type the show command to display the actual power consumption.
-> show /SP/powermgmt actual_power
Note - The actual_power is the same as /SYS/VPS. The actual_power is the value returned by the sensor. |
Monitor Individual Power Supply Consumption |
1. Log in to the ILOM server SP CLI or ILOM CMM CLI.
2. Type the show command to display the individual power supply consumption.
-> show /SYS/platform_path_to_powersupply/INPUT_POWER|OUTPUT_POWER

The following table lists and describes the properties of the CLI sensors. Both sensors, INPUT_POWER and OUTPUT_POWER, have the same properties.
Note - Power sensors are not supported on server modules (blades). |

Monitor Power Consumption History |
1. Log in to ILOM the server SP CLI or the ILOM CMM CLI.
2. Use the show command to view actual power consumption.
3. Use the show command to display 15-, 30-, and 60-second rolling power usage average, and to display a choice of targets for average consumption history.
4. Use the show command to display average consumption history by the minute or hour respectively, type the following command with the appropriate target named.
5. Use the show command to display sample set details such as time stamp and power consumed in watts.
Configure Server SP Power Policy |
1. Log in to the ILOM server SP CLI.
2. Type the set command to set the power policy:
-> set /SP/powermgmt policy=Performance|Elastic
3. Type the show command to display the power policy:
View and Configure Notification Thresholds Using the CLI |
1. Log in to ILOM server SP CLI or the ILOM CMM CLI.
2. To view the current settings, type:
3. To set the value for notification thresholds, type:
Note - Setting the notification threshold value to 0 (zero) will disable the notification threshold option. |
View Server Power Allocations for All System Components |
1. Log in to the ILOM server SP CLI.
2. To view the sum of power allocated to all components in the system, type the following command:
-> show /SP/powermgmt allocated_power
View Server Component Power Allocations |
1. Log in to the ILOM server SP CLI.
2. To view power allocated to a component category (fans, CPUs, and so forth), type the following command:
-> show /SP/powermgmt/powerconf/component_type
Where component_type is the name of the component category.
For example, to view the power allocated to all CPUs (component category), you would type:
-> show /SP/powermgmt/powerconf/CPUs
Note - For each command, the read-only value for the maximum power consumed by the component is returned, measured in watts. |
3. To view the power allocated to a specific component, type the following command:
-> show /SP/powermgmt/powerconf/component_type/component_name
For example, to view the power allocated to a specific CPU, you would type:
-> show /SP/powermgmt/powerconf/CPUs/CPUn
Where n is the installed location number of the CPU.
Other rackmount server components can include:
Other server module components can include:
View CMM Power Allocations for All Chassis Components |
1. Log in to the ILOM CMM CLI.
2. To view the sum of power allocated to all chassis system components, do one of the following:
-> show /CMM/powermgmt allocated_power
-> show /CMM/powermgmt granted_power
3. To view the remaining power available to allocate to blade slots, type the following command:
-> show /CMM/powermgmt allocatable_power
View CMM Component Power Allocations |
1. Log in to the ILOM CMM CLI.
2. To view power allocated to a component category (fans, blade slots, and so forth), type the following command:
-> show /CMM/powermgmt/powerconf/component_type
Where component_type is the name of the component category.
For example, to view the power allocated to all blade slots (component category), you would type:
-> show /CMM/powermgmt/powerconf/bladeslots
