Patent ID: 7882216

Claim:
A computer implemented method for analyzing performance metrics for a virtualized process collection, the computer implemented method comprising: determining, by a processing unit in a computer, a performance state value of a metric in a virtualized process collection using information in a stack tier policy, wherein the stack tier policy specifies at least a weight property, a limit property, a maximum property, and a minimum property for the metric, and wherein the weight property is multiplied by a collected value of the metric to calculate a weight adjusted metric value; responsive to determining that the value of the metric exceeds the maximum property specified in the stack tier policy, determining that a value of the metric is higher than values for all recorded metrics and storing the value of the metric as a highest value; responsive to calculating a weight adjusted metric value for a plurality of metrics in the virtualized process collection, determining an average performance state value of the plurality of metrics in the virtualized process collection by calculating a weight adjusted total of all weight adjusted metric values divided by a weight property total; and responsive to determining that the highest value is higher than the average performance state value of the plurality of metrics in the virtualized process collection, using the highest value as a performance state of the virtualized process collection.
