How to Retrieve the Sensor Group Information

Language:

At the command prompt, type the following:
# snmpwalk -v 2c -c public -m ALL localhost SUN-HW-MONITORING-MIB::sunHwMonSensorGroup | grep '\.9 = '
where grep '\.9 = ' is filtering a property of the FRU we are interested in.
You should see output similar to the following:
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorType.9 = INTEGER: voltage(133)
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorName.9 = STRING: /SYS/MB/V_+12V
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorParentFruIndex.9 = INTEGER: 146
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorParentFruName.9 = STRING: /SYS/MB
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorAlarmStatus.9 = INTEGER: cleared(1)
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorStateDescr.9 = STRING: Normal
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorCurrentValue.9 = INTEGER: 12160
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorBaseUnit.9 = INTEGER: volts(4)
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorExponent.9 = INTEGER: -3
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorUpperNonRecoverableThreshold.9 = INTEGER: 14994
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorUpperCriticalThreshold.9 = INTEGER: 13986
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorUpperNonCriticalThreshold.9 = INTEGER: 12978
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorLowerNonRecoverableThreshold.9 = INTEGER: 8946
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorLowerCriticalThreshold.9 = INTEGER: 9954
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorLowerNonCriticalThreshold.9 = INTEGER: 10962
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorEnabledThresholds.9 = BITS: FC lowerThresholdNonCritical(0) upperThresholdNonCritical(1) lowerThresholdCritical(2) upperThresholdCritical(3) lowerThresholdFatal(4) upperThresholdFatal(5)
Note - If the server uses Oracle ILOM 2.0, the following lines are returned:
SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorType.9 = INTEGER: unknown(1)

SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorParentFruIndex.9 = INTEGER: -1

SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorParentFruName.9 = STRING:

This is expected behavior because this information is specific to Oracle ILOM 3.0.

Tip - When analyzing the following lines, do not forget that the sunHwMonNumericVoltageSensorCurrentValue is returned using the exponent set in sunHwMonNumericVoltageSensorExponent.SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorCurrentValue.9 = INTEGER: 12290SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorBaseUnit.9 = INTEGER: volts(4)SUN-HW-MONITORING-MIB::sunHwMonNumericVoltageSensorExponent.9 = INTEGER: -3This example has an exponent of -3, which means that the voltage value of sunHwMonNumericVoltageSensorCurrentValue has to be multiplied by 10^-3, resulting in 12.290 volts.
