System for first pass filtering of anomalies and providing a base confidence level for resource usage prediction in a utility computing environment

Abstract

Provided is a system for monitoring resources in a utility computing environment (UCE). Measurements are evaluated to determine whether or not a particular resource requires remedial or other type of action. A sliding measurement window is employed to assemble a number of measurements corresponding to a particular resource. The number of intervals in a sliding measurement window is based upon best practices corresponding to the resource being measured and analyzed. A first threshold-crossing event and subsequent events are stored until the window is full, or closed. When the window is closed, the threshold-crossing measurements are analyzed to determine whether or not there exists an issue with the resource that requires action. Once a window has been closed and analyzed, the first threshold-crossing event and each subsequent event up to a second threshold-crossing event are discarded and the window reopens.
