If you look in Trap Definition for Trap OID 1.3.6.1.4.1.11.2.14.12.1.6.3 you will find the hpicfSensorTrap that has two parameters hpicfSensorStatus and hpicfSensor Description. This is installed by default in IMC 5.2.
However, to get this to work you have to manually add a Trap to Alarm adding the trap name under Trap Type.
When I do walk mib on a device with a faulty power supply it shows that power supply 1 status is bad(2), but an alarm is not generated in IMC.
Is there something else you have to do?
I have set the trap source to match selected device IP, trap type hpicfSensorTrap and parameter sensor status to bad(2) but IMC is not generating the alarm.
