cmTrapTypeLogProbableCause is a read-only integer code recorded in the trap-type configuration table indicating the probable-cause value associated with a given event type entry. An administrator references this alongside the event type to understand how the system categorizes the underlying condition before it becomes a trap. For example, an operator documenting the meaning of the system's trap types would record the cmTrapTypeLogProbableCause value tied to each entry for later reference.
