Power Supply Trap

[qos]

I have put the hpicfDcPower.mib (POWERSUPPLY-MIB) in \iMC\client\TrapMIB in order to import the trap definition to generate an alarm when the power supply fails but I can't get the Trap OID for this. How do I get this working?

After you put the file in <IMC>\client\trapMIB, did you Compile/Import the MIB file?

Go to Alarm -> Trap Management -> Trap Definition -> Import trap definition from MIB file.

Does your new MIB file show up there? 

[qos]

SNMPv2-MIB

IF-MIB

ENTITY-MIB

It just contains the above

[qos]

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.

Adding Trap definitions + Trap to Alarm rules is important, but it won't help if you've already got a faulty power supply. 

Devices only send traps when the state changes. So if the power supply failed, it would send a trap at that time. But if IMC wasn't configured to handle that trap, it gets lost.

You need to poll for that specific OID. You'll need to add custom monitoring for that OID, and set thresholds to trigger when it changes.
