Abstract
A method and apparatus for correlating faults in a networking system. A database of fault rules is maintained along with and associated probable causes, and possible solutions for determining the occurrence of faults defined by the fault rules. The fault rules include a fault identifier, an occurrence threshold specifying a minimum number of occurrences of fault events in the networking system in order to identify the fault, and a time threshold in which the occurrences of the fault events must occur in order to correlate the fault. Occurrences of fault events in the networking system are detected and correlated by determining matched fault rules which match the fault events and generating a fault report upon determining that a number of occurrences for the matched fault rules within the time threshold is greater than or equal to the occurrence threshold for the matched fault rules.
