When the correlation coefficient exceeds the threshold, the device pair is grouped into a process group. Other device pairs exceeding the threshold are likewise grouped into the process group. Multiple processes may be determined with the process algorithm. Sensors may also be grouped manually with the process group containing monitoring devices, which may include virtual monitoring devices. Alarms associated with monitoring devices and sensors are aggregated into one process alarm.
