Trigger a default alarm

I am using vCO 5 with vCenter 5 plug-in.  I am creating a workflow that prepares a brand new VM that is brought into the environment (it connects the VM to the Active Directory, HIDS, etc).  I would like to trigger a default alarm (for example, the VM Error alarm that gets triggered by the VcGeneralVMErrorEvent) when this workflow fails.  What would be code required to do this?

Alternatively, can I create an alarm that is triggered by the "LogUserEvent"?

Thanks in advance for your help!
