What is a fault, and how does DFM classify faults?
DFM considers an event to be a fault when it surpasses a threshold for acceptable behavior. When this happens, DFM generates a fault notification (or alarm), which is displayed in the Monitoring and Administration Consoles. DFM displays two kinds of fault notifications: •Symptomatic notifications, which identify a single fault (symptom). •Compound notifications, which identify one or more related symptoms. In DFM terminology, a compound notification is a roll-up of related symptoms. Compounds are sometimes called aggregates (in the adapter configuration files), or simply exceptions (from the naming standard for compounds—OperationalException, PerformanceException, and so forth).
