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

A system for evaluating resources coupled to a computing system, comprising:

• a processor;
• a physical, computer-readable memory coupled to the processor;
• a polling interval corresponding to a resource;
• a number of time intervals, each time interval corresponding to the polling interval and the number of time intervals corresponding to a user-defined period threshold;
• a measurement threshold corresponding to a measurement associated with the resource;
• a duration threshold, wherein the polling interval is longer than the duration threshold;
• logic, stored on the memory for execution on the processor, for storing in the memory a first threshold-crossing measurement and corresponding evaluation indicating that the first threshold-crossing measurement crosses the measurement threshold;
• logic, stored on the memory for execution on the processor, for storing in the memory a plurality of measurements and corresponding evaluations subsequent to the first threshold-crossing measurement, each evaluation corresponding to whether or not the corresponding measurement crosses the measurement threshold;
• logic, stored on the memory for execution on the processor, for determining when a total number of measurements, wherein the total number of measurements includes the first threshold-crossing measurement and subsequent measurements, equals the number of time intervals;
• logic, stored on the memory for execution on the processor, for calculating, once the total number of measurements equals the number of time intervals, a score corresponding to the number of total measurements that both cross the threshold and are included in any group of contiguous measurements in which the number of measurements in the corresponding group of contiguous measurements exceed the duration threshold;
• and
• logic, stored on the memory for execution on the processor, for signaling when the score crosses a scoring threshold.
