Abstract

A change monitoring system for a computer system includes programs for creating and managing a plurality of templates representative of the computer system. A repository stores the templates. A communications network communicates with plural platforms of the computer system. Programs associate the templates with corresponding ones of the platforms and plural software products of the computer system. Other programs monitor the computer system for changes to the platforms or the software products with respect to the templates.
