1. A method for identifying causes of performance metric changes in a network, the method comprising:
- selecting, from a pool of network event counters, a plurality of candidate counters relevant to a performance metric;
grouping candidate counters into clusters of similar counters;
selecting, from each cluster, one or more representative counters; and
fitting the selected representative counters to a model of the performance metric to determine thereby a set of representative counters most relevant to the performance metric.

Abstract
A method and system for identifying causes of performance metric changes in a network by selecting, from a pool of network event counters, a plurality of candidate counters relevant to a performance metric; grouping the candidate counters into clusters of similar counters; selecting, from each cluster, one or more representative counters; and fitting the selected representative counters to a model of the performance metric to determine thereby a set of representative counters most relevant to the performance metric.

18. An apparatus for use in a network management system and for identifying causes of performance metric changes in a network, the apparatus comprising:
-
a processor configured to; select, from a pool of network event counters, a plurality of candidate counters relevant to a performance metric; group candidate counters into clusters of similar counters; select, from each cluster, one or more representative counters; and fit the selected representative counters to a model of the performance metric to determine thereby a set of representative counters most relevant to the performance metric.

19. A tangible and non-transitory computer readable medium including software instructions which, when executed by a processer, perform a method for identifying causes of performance metric changes in a network, the method comprising:
-
selecting, from a pool of network event counters, a plurality of candidate counters relevant to a performance metric; grouping candidate counters into clusters of similar counters; selecting, from each cluster, one or more representative counters; and fitting the selected representative counters to a model of the performance metric to determine thereby a set of representative counters most relevant to the performance metric.
