Power meter graph display options
Graph Type
• Last 20 Minutes—Displays the power usage of the server over the last 20 minutes. The iLO firmware
collects power usage information for this graph every 10 seconds.
• Last 24 hours—Displays the power usage of the server over the last 24 hours. The iLO firmware
updates power usage information for this graph every 5 minutes.
Chart data
Use the following check boxes to customize the data included in power meter graphs.
• Power Cap—The configured power cap during the sample. Power cap data is displayed in red in
power meter graphs.
â—¦ A power cap limits average power draw for extended periods of time.
â—¦ Power caps are not maintained during server reboots, resulting in temporary spikes during boot.
â—¦ Power caps set lower than the specified percentage threshold between maximum power and idle
power might become unreachable because of changes in the server. Hewlett Packard Enterprise
does not recommend configuring power caps lower than this threshold. Configuring a power cap
that is too low for the system configuration might affect system performance.
• Maximum—The highest instantaneous power reading during the sample. iLO records this value on a
subsecond basis. Maximum power data is displayed in purple in power meter graphs.
