Monitoring performance index for of CPU, memory, and I/O modules using
web interface
To monitor the performance index of CPU, memory, and I/O modules, in the iDRAC web interface, go to
Overview → Hardware. The Hardware Overview page displays the following:
• Hardware section — Click the required link to view the health of the component.
• 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.
– 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 I/O 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 Command Line Reference Guide available at
dell.com/esmmanuals.
Checking the system for fresh air compliance
Fresh air cooling directly uses outside air to cool systems in the data center. Fresh air compliant systems
can operate above its normal ambient operating range (temperatures up to 113 °F (45 °C)).
NOTE: Some servers or certain configurations of a server may not be fresh air compliant. See the
specific server manual for details related to fresh air compliance or contact Dell for more details.
To check the system for fresh air compliance:
1. In the iDRAC Web interface, go to Overview → Server → Power / Thermal → Temperatures.
The Temperatures page is displayed.
2. See the Fresh Air section that indicates whether the server is fresh air compliant or not.
Viewing historical temperature data
You can monitor the percentage of time the system has operated at ambient temperature that is greater
than the normally supported fresh air temperature threshold. The system board temperature sensor
reading is collected over a period of time to monitor the temperature. The data collection starts when the
system is first powered on after it is shipped from the factory. The data is collected and displayed for the
