INSTRUMENTATION:
Environment = CiscoEntityFRU:DeviceID
The following MIBs are polled and must be present in the device SNMP agent:
entityMIB - 1.3.6.1.2.1.47
ciscoEntitySensorMIB - .1.3.6.1.4.1.9.9.91
ciscoEntityFRUControlMIB -. 1.3.6.1.4.1.9.9.117
For discovery of environmental objects we are interested in the following values of the entityMIB OID
entPhysicalClass-1.3.6.1.2.1.47.1.1.1.1.5
6:powerSupply
7:fan
8:sensor
In addition to entPhysicalClass, the following OIDs from the ciscoEntitySensorMIB and ciscoEntityFRUControlMIB must be present for successful discovery and monitoring of PowerSupply, Fan, VoltageSensor and TemperatureSensor objects:
PowerSupply
cefcFRUPowerOperStatus-.1.3.6.1.4.1.9.9.117.1.1.2.1.2
Fan
cefcFanTrayOperStatus-.1.3.6.1.4.1.9.9.117.1.4.1.1.1
TemperatureSensor/ VoltageSensor
entSensorPrecision-.1.3.6.1.4.1.9.9.91.1.1.1.1.3
entSensorValue-.1.3.6.1.4.1.9.9.91.1.1.1.1.4
entSensorStatus-.1.3.6.1.4.1.9.9.91.1.1.1.1.5
