Methods, apparatus and articles of manufacture to perform root cause analysis for network events

摘要

Example methods, apparatus and articles of manufacture to perform root cause analysis for network events are disclosed. An example method includes retrieving a symptom event instance from a normalized set of data sources based on a symptom event definition; generating a set of diagnostic events from the normalized set of data sources which potentially cause the symptom event instance, the diagnostic events being determined based on dependency rules; and analyzing the set of diagnostic events to select a root cause event based on root cause rules.

主权项

1. A method of determining a root cause of a network problem, comprising:
identifying, with a processor, a symptom event from a set of events based on a symptom event definition; classifying, with the processor, an event from the set of events as a diagnostic event that potentially caused the symptom event, the diagnostic event classified based on a dependency rule, the dependency rule including a spatial model to classify the event as the diagnostic event when the event is spatially related to the symptom event; and analyzing, with the processor, the diagnostic event to determine whether the diagnostic event is a root cause event based on a root cause rule.
