Fault
Diagnosis service provides mechanisms to determine the location of faults by
running diagnostic tests on application/system/network entities. In order to
diagnose root cause alarm filtering/correlation algorithms and fault data summarization
and analysis may also be used. Sometimes, identification of the root cause may
be difficult and require extensive analysis. In such cases, a partial diagnosis
is done to locate and isolate the fault in order to restore service quickly,
and a follow-up full investigation identifies the root cause. Many artificial
intelligence and statistical approaches for fault diagnosis are suggested and
embedded in intelligent agents of new enterprise management products.
