Power Tracking Statistics
• Statistic:
– Cumulative System Power displays the current cumulative energy
consumption (in KWh) for the server. The value represents the total
energy used by the system. You can reset this value to 0 by clicking
Reset at the end of the table row.
–
System Peak Power specifies the system peak value in Watts within
the interval specified by the
Measurement Start Time and Measure
Current Time
. You can reset this value to 0 by clicking Reset at the
end of the table row.
–
System Peak Amperage specifies the system peak amperage within the
interval specified by the
Measurement Start Time and Measure
Current Time
. You can reset this value to 0 by clicking Reset at the
end of the table row.
•
Measurement Start Time displays the date and time recorded when the
system energy consumption value was last cleared and the new
measurement cycle began. For
Cumulative System Power , System Peak
Amperage
, and System Peak Power statistics, you can reset each value to 0
by clicking
Reset at the end of the table row; however, it will persist
through a system reset or CMC failover operation.
•
Measurement Current Time for Cumulative System Power displays the
current date and time when the system energy consumption was
calculated for display. For
System Peak Amperage and System Peak Power ,
the
Peak Time fields display the time when these peaks occurred.
•
Reading : The amount of power (in KWh) used since the counter was started.
NOTE: Power Tracking Statistics are maintained across system resets and so reflect
all activity in the interval between the stated Start and Finish Times.The Reset Max
Peaks button will reset to peak statistics value. In the next table, Power Consumption
data is not maintained across system resets and so will reset back to peak statistics
value. The power values displayed are cumulative averages over the respective time
interval (previous minute, hour, day and week). Since the Start to Finish time intervals
here may differ from those of the Power Tracking Statistics ones, peak power values
(Max Peak Watts versus Max Power Consumption) may differ.
