Claim One:
1. A method for analyzing a change in a network, comprising: accessing multiple counters of a network system to obtain observed data, each counter of the multiple counters recording samples for a metric in the network; performing a classification and regression tree (CART) analysis of the obtained observed data to select a subset of the multiple counters whose metrics are related to a target network performance; extrapolating with a kriging-based analysis of the subset of the multiple counters selected from the CART analysis, wherein said extrapolating yields data for the selected subset of the multiple counters beyond the observed data; and indicating whether a criterion of a to-be-provisioned workload will be satisfied based, at least in part, on the data yielded from said extrapolating and whether a criterion of an already provisioned workload will be violated based, at least in part on the data yielded from the extrapolating.
