Select one or more of the following check boxes, and then click Refresh Page to update the graphs.
•
Min (static low)—The minimum value observed during a measurement period. Typically, the
20-minute graph measures a minimum value every 10 seconds, which matches the average
value. The 24-hour graph can capture minimum values lower than the 5-minute average value.
•
Avg—The mean power reading during the sample.
•
Peak—The highest instantaneous power reading during the sample. iLO records this value on
a subsecond basis.
•
Cap—The configured power cap during the sample. If the power cap is not configured or is
not supported, it does not appear.
◦ A power cap limits average power draw for extended periods of time.
◦ Power caps are not maintained during server reboots, resulting in temporary spikes during
boot.
◦ Power caps set for less than 50% of the difference between maximum power and idle
power might become unreachable because of changes in the server. HP does not
recommend configuring power caps for less than 20%. Configuring a power cap that is
too low for the system configuration can affect system performance.

The following options are also available:
•
Power Unit—Select a value on the Power Unit list to show the power readings in either watts
or BTU/hr.
