One embodiment of a method of the present invention for monitoring computer resources provides for retrieving a set of resource-metric records for a predetermined time interval, forming a first mathematical matrix containing metric's values arranged on date-time and resource-metric axes, creating a second mathematical matrix containing features and a third mathematical matrix containing weights, building a feature relationship tree, generating a predicted value for the resource-metric identifier, determining a variance between predicted value and metric's value, and triggering an alert if the variance exceeds a predetermined alert threshold.
