Claim One:
1. A method, comprising: performing, using one or more computer systems, identifying vectors representing network events observed by a network monitoring system, each vector including: a dimension, an indication of a sampling ratio with which a respective network event was observed, and a value associated with the dimension; calculating a Key Performance Indicator (KPI) corresponding to the observed network events for the dimension based, at least in part, upon the values; and calculating a confidence associated with the KPI, based, at least in part, upon the sampling ratios, wherein calculating the confidence further includes: performing, using the one or more computer systems, estimating a number of network events (KN) that would have been observed by the network monitoring system in the absence of sampling; determining a number of observed network events (Kn); and calculating a standard deviation (Kσ) of the values.
