There are described a system, apparatus and/or method according to which collected history data from monitorable and/or manageable entities within a server estate or data center is used to tailor a model to the past behavior and/or loading upon individual ones or parts of ones of the entities. The tailored model can then be used to predict a future value for one or more metrics included in the history data for an entity or part of an entity under consideration. The predicted value can then be used to determine whether some form of corrective action is required in respect of the entity, entity part or some other entity or entity part. Alternatively or in addition, predicted values for more than one entity or entity part can be aggregated to determine whether some form of corrective action is required in respect of the entity, entity part or some other entity or entity part. A corrective action can be applied on an automated or on a manual basis.
