You can reset the peak utilization for a particular sensor. Click Reset Historical Peak. You must have Configure
privilege to reset the peak value.
Performance Metrics section:
Displays status and present reading
Displays or specifies the warning threshold utilization limit. You must have server configure privilege to set the threshold
values.
For information about the displayed properties, see the iDRAC Online Help.
Monitoring performance index for of CPU, memory, and input
output modules using RACADM
Use the SystemPerfStatistics sub command to monitor performance index for CPU, memory, and I/O modules. For more
information, see the iDRAC RACADM CLI Guide available at https://www.dell.com/idracmanuals.
Setting warning threshold for power consumption
You can set the warning threshold value for the power consumption sensor in the rack and tower systems. The warning/critical
power threshold for rack and tower systems may change, after the system is power-cycled, based on PSU capacity and
redundancy policy. However, the warning threshold must not exceed the critical threshold even if Power Supply Unit capacity of
the redundancy policy is changed.
The warning power threshold for blade systems is set to power allocation of CMC(for non-MX platforms) or OME Modular (for
MX platforms).
If reset to default action is performed, the power thresholds will be set to default.
You must have Configure user privilege to set the warning threshold value for power consumption sensor.
NOTE: The Warning Threshold value is reset to the default value after performing a racreset or an iDRAC update.
Setting warning threshold for power consumption using web
interface
1. In the iDRAC Web interface, go to System > Overview > Present Power Reading and Thresholds.
2. In the Present Power Reading and Thresholds section, click Edit Warning Threshold.
The Edit Warning Threshold page is displayed.
3. In the Warning Threshold column, enter the value in Watts or BTU/hr.
The values must be lower than the Failure Threshold values. The values are rounded off to the nearest value that is
divisible by 14. If you enter Watts, the system automatically calculates and displays the BTU/hr value. Similarly, if you enter
BTU/hr, the value for Watts is displayed.
4. Click Save. The values are configured.
Executing power control operations
iDRAC enables you to remotely perform a power-on, power off, reset, graceful shutdown, Non-Masking Interrupt (NMI), or
power cycle using the Web interface or RACADM.
You can also perform these operations using Lifecycle Controller Remote Services or WSMan. For more information, see the
Lifecycle Controller Remote Services Quick Start Guide available at https://www.dell.com/idracmanuals and the Dell Power
State Management Profile document available at https://www.dell.com/support.
Server power-control operations initiated from iDRAC are independent of the power-button behavior configured in the BIOS.
You can use the PushPowerButton function to gracefully shut down the system, or power it on, even if the BIOS is configured
to do nothing when the physical power button is pressed.
