How to Use the CLI to Monitor Power Usage and Set Notification Thresholds

This task describes how to monitor power usage and set up to two thresholds so you can be notified when the server exceeds a power limit.

1. Log in to the server SP by opening an SSH connection at a terminal window:

   $ ssh root@SPIPaddress

   Password: password

   where:

   • SPIPaddress is the IP address of the server's service processor.

   • password is the password for the account. The default password for the root account is changeme. If you choose to use another user account, make sure it has Admin privileges.

   The Oracle ILOM CLI prompt appears (->).

2. Enter the following command:

   -> show /SP/powermgmt

   Example output might look like:

   -> show /SP/powermgmt
   
    /SP/powermgmt
       Targets:
           powerconf
   
       Properties:
           actual_power = 604
           permitted_power = 4576
           allocated_power = 1658
           available_power = 4576
           threshold1 = 0
           threshold2 = 0
   
       Commands:
           cd
           set
           show

   where:

   • actual_power displays the current system input power (in watts) consumption.

   • permitted_power displays the maximum power consumption (in watts) expected for the system.

   • allocated_power displays the power allocated in watts to the system components.

   • available_power displays the input power capacity (in watts) that is available to system components.

3. Alternately, you can view total power consumed by the system by entering the command:

   -> show /SYS/VPS

   Example output might look like:

   -> show /SYS/VPS
   
    /SYS/VPS
       Targets:
           history
   
       Properties:
           type = Power Unit
           ipmi_name = VPS
           class = Threshold Sensor
           value = 601,500 Watts
           upper_nonrecov_threshold = N/A
           upper_critical_threshold = N/A
           upper_noncritical_threshold = N/A
           lower_noncritical_threshold = N/A
           lower_critical_threshold = N/A
           lower_nonrecov_threshold = N/A
           alarm_status = cleared
   
       Commands:
           cd
           show

   The value of /SYS/VPS is equivalent to the value of /SYS/powermgmt actual_power.

4. To set a notification threshold, type the following. You can set two thresholds.

   -> cd /SP/powermgmt
   -> set threshold1|2 = n

   where n represents watts, for example, 4000.

   For example:

   -> cd /SP/powermgmt
   -> set threshold1 = 4000
