Abstract: A device, computer readable medium and method for monitoring a group of entities. The method includes: receiving entities information, entity dependency information and entity association information; generating a model of the group of entities that includes multiple abstract dependency instances; evaluating at least one parameter of the group of entities in view of at least one parameter of the model; and dynamically updating the model. A method for dependency resolution, the method includes: defining multiple levels of reactive rules; detecting a certain level situation in response to a lower level event and a previous certain level situation; and providing at least one dependency resolution indication in response to an detection of a high level situation.
