METHOD AND APPARATUS FOR RESPONDING TO THRESHOLD EVENTS FROM HETEROGENEOUS MEASUREMENT SOURCES

A system is disclosed that collects heterogeneous scalar measurement data over a network from a plurality of devices connected to the network, and automatically normalizes the collected heterogeneous scalar measurement data based on a threshold to generate an event based on a threshold crossing. In an embodiment, the system automatically derives a measurement from the collected heterogeneous scalar measurement data; and automatically scales the derived measurement or the collected heterogeneous scalar measurement data. In another embodiment, the system normalizes the collected heterogeneous scalar measurement data, the scaled derived measurement, the scaled collected heterogeneous scalar measurement data, or the derived measurement.
