METHODS, APPARATUS AND ARTICLES OF MANUFACTURE TO PERFORM ROOT CAUSE ANALYSIS FOR NETWORK EVENTS
First Claim
Patent Images
1. A method of determining a root cause of a network problem, comprising:
- identifying a symptom event from a set of events based on a symptom event definition;
classifying 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 the diagnostic event to determine whether the diagnostic event is a root cause event based on a root cause rule.

Abstract
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.

8. An apparatus comprising:
-
a processor; and a memory storing machine readable instructions that, when executed by the processor, cause the processor to perform the operations comprising; gathering data related to network events; normalizing the network events to form a normalized set; identifying a set of diagnostic events joined to a symptom network event within the normalized set, the diagnostic events having a physical location related to the symptom network event identified using a spatial model; and identifying a root cause event of the symptom network event based on the set of diagnostic events. - View Dependent Claims (9, 10, 11, 12, 13)
