Monitoring data categorization and module-based health correlations

Architecture for aggregating health alerts from a number of related components into a single aggregated health state that can be analyzed to isolate the component responsible for the fault condition. In a hierarchy of related components within various component groups in a computer system, a number of health indicators can indicate alerts occurring in one or more of the related components whereas the fault condition occurs in only one component upon which the other components depend. The health indicators of related components are aggregated into an aggregated health state for each component group. These aggregated health states are analyzed to identify the related component associated with a root cause of the alert condition for an affected component group.
