Monitoring and managing power in iDRAC
You can use iDRAC to monitor and manage the power requirements of the managed system. This helps to protect the system
from power outages by appropriately distributing and regulating the power consumption on the system.
The key features are:
● Power Monitoring — View the power status, history of power measurements, the current averages, peaks, and so on for
the managed system.
● Power Capping — View and set the power cap for the managed system, including displaying the minimum and maximum
potential power consumption. This is a licensed feature.
● Power Control — Enables you to remotely perform power control operations (such as, power on, power off, system reset,
power cycle, and graceful shutdown) on the managed system.
● Power Supply Options — Configure the power supply options such as redundancy policy, hot spare, and power factor
correction.
Topics:
• Monitoring power
• Setting warning threshold for power consumption
• Executing power control operations
• Power capping
• Configuring power supply options
• Enabling or disabling power button
• Multi-Vector Cooling
Monitoring power
iDRAC monitors the power consumption in the system continuously and displays the following power values:
● Power consumption warning and critical thresholds.
● Cumulative power, peak power, and peak amperage values.
● Power consumption over the last hour, last day or last week.
● Average, minimum, and maximum power consumption.
● Historical peak values and peak timestamps.
● Peak headroom and instantaneous headroom values (for rack and tower servers).
NOTE:
The histogram for the system power consumption trend (hourly, daily, weekly) is maintained only while iDRAC is
running. If iDRAC is restarted, the existing power consumption data is lost and the histogram is restarted.
NOTE: After iDRAC firmware update or reset, the power consumption graph will be wiped / reset.
Monitoring performance index of CPU, memory, and input output
modules using web interface
To monitor the performance index of CPU, memory, and I/O modules, in the iDRAC web interface, go to System >
Performance.
● System Performance section — Displays the current reading and the warning reading for CPU, Memory and I/O utilization
index, and system level CUPS index in a graphical view.
● System Performance Historical Data section:
○ Provides the statistics for CPU, memory, IO utilization, and the system level CUPS index. If the host system is powered
off, then the graph displays the power off line below 0 percent.
