There are 3 ways to know about electric power consumption:

1. ILOM Web.

Login to ilom of your server and click to "Power Management" at left side down.

  Power Management > Consumption - current value

  Power Management > History - historical value for the last hour or 14 days.














2. ILOM Cli

show /SP/powermgmt actual_power
show /SP/powermgmt permitted_power

-> show /SP/powermgmt actual_power

  /SP/powermgmt
    Properties:
        actual_power = 424


-> show /SP/powermgmt permitted_power

  /SP/powermgmt
    Properties:
        permitted_power = 740


3. ipmitool
