A system and method for collecting information on components in an information technology (IT) system. This embodiment features discovering components in the IT system, determining at least one dependency between two or more of the discovered components, and tracking changes to the discovered components and the dependency between two or more of the discovered components. The discovery of components can be carried out using fingerprints of components, which can include key elements of the component that exist in a full model of all of the elements of the component.
