Patent ID: 8843347

Claim:
A monitoring system for monitoring health of a monitored system, the monitoring system comprising: a receiver module configured to receive a plurality of sensor data relating to the monitored system and to receive textual data relating to the monitored system; an associative memory configured to store the sensor data, the textual data and associated time values and to establish associations between at least some of the sensor data and the textual data; a dynamic change identification module configured to identify an instance in which the sensor data changes by at least a predefined amount within a time period less than a predefined temporal threshold so as to represent a dynamic change in condition; and a correlation module configured to identify an instance in which textual data is associated with the sensor data proximate the dynamic change in condition so as to correlate the sensor data and the textual data, wherein the correlation module is configured to correlate the sensor data and the textual data by identifying an instance in which the time value associated with the textual data is within a predefined period of time from a time at which the sensor data experienced the dynamic change in condition.
