Abstract: A system comprises an executable graph-based model. The executable graph-based model comprises a first overlay node. The first overlay node comprises processing logic that is operable to interact with one or more associated nodes of the executable graph-based model. Further, the executable graph-based model comprises a first node that has the first overlay node associated therewith. The system further comprises a processing unit configured to receive a first stimulus associated with the first overlay node and, in response to the first stimulus being received, cause execution of said processing logic of the first overlay node. Execution of said processing logic of the first overlay node is based on the first node.

Abstract: A method, non-transitory computer readable medium, and apparatus for assessing efficiency of a data center includes querying, based on a system management protocol, each of a plurality of information technology (IT) devices to obtain utilization information. A power rating value is obtained for each of the plurality of IT devices. An IT power consumption value for the plurality of IT devices is generated based on the utilization information for the plurality of IT devices and the power rating values. A value for at least one efficiency metric is generated and output based on the IT power consumption value.
