3.2.2 Intake air temperature
Intake air temperature is given by executing IPMI commands to BMC.
The example below uses Open IPMI driver and IPMITool that are open source software. For Red Hat Enterprise
Linux 5, OpenIPMI driver is contained in Inbox driver. IPMITool is contained in: OpenIPMI-tools-[version].rpm.
Execution example
# ipmitool sdr type Temperature
Execution result
Baseboard Temp4
Fnt Pnl Temp
CPU1_DIMM1 Temp
CPU1_DIMM2 Temp
CPU1_DIMM3 Temp
CPU1_DIMM4 Temp
CPU1_DIMM5 Temp
CPU1_DIMM6 Temp

The output above shows the following in a line in order.
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
