Power Monitoring and Management 295
• Measurement Finish Time displays the current date and time when the
system energy consumption was calculated for display.
Peak Time displays
the time when the peaks occurred.
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 button will reset the respective field back to zero. In the next table,
Power Consumption data is not maintained across system resets and so will reset
back to zero on those occasions. 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.
Power Consumption
• Displays the average, maximum, and minimum power consumption in the
system for the last minute, last hour, last day, and last week.
• Average Power Consumption: Average over previous minute, previous
hour, previous day and previous week.
• Max and Min Power Consumption: The maximum and minimum power
consumptions observed within the given time interval.
• Max and Min Power Time: The time when the maximum and minimum
power consumptions occurred.
Headroom
• System Instantaneous Headroom displays the difference between the
power available in the power supply units and the system's current power
consumption.
•
System Peak Headroom displays the difference between the power
available in the power supply units and the system's peak power
consumption.
