The process includes the step of selecting a correlation time such that a correlation occurs between an early pulse and a later pulse on a first hydrophone and a second hydrophone respectively, wherein the first hydrophone and the second hydrophone are maximally separated in the spatial correlation sonar hydrophone array. The changes can reflect changes in the IT environment, changes to the business application, changes to the business environment andor failures within the environment, as examples.
