Chapter 3 Appendix
1st: Sensor name
2nd: Sensor number
3rd: Sensor status
ok indicates that the status has not reached a point of warning or danger.
4th: Sensor monitoring point
5th: The current reading of the sensor
The sensor indicating intake air temperature contains Amb, Ambient, or Fnt Pnl Temp in its name.
The data in the above example is obtained from the sensor that contains Fnt Pnl Temp in its ID and the
intake air temperature is 27°C.
3.2.3
Processor utilization
The utilization rate of all logical processors is given by executing the mpstat command provided in a Linux
distribution.
For Red Hat Enterprise Linux 5, sysstat-[version].rpm contains the command.
• Execution example
# mpstat -P ALL
• Execution result
Linux 2.6.18-164.el5 (localhost.localdomain) 11/17/09

You can acquire the processor utilization rate by subtracting %idle from 100%.
