    摘要： Methods, apparatus and articles of manufacture for hierarchical anomaly localization and prioritization are disclosed. An example method disclosed herein comprises obtaining reported status for a plurality of nodes of a hierarchical topology, the reported status for a particular node being at least one of normal, abnormal or indeterminate, and determining a subset of root cause abnormal nodes, a root cause abnormal node included in the subset of root cause abnormal nodes having a total number of abnormal direct descendent nodes and indeterminate direct descendent nodes that is greater than a number of normal direct descendent nodes of the root cause abnormal node.

    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.
