A target software behavior pattern recognition and analysis tool is disclosed that operates during the real-time execution of monitored target software on a computer, derives a subset of measurements indicating the target software performance and activity, automatically derives a baseline from the subset of measurements, and establishes a state of health of the target software based on comparing real-time measurements to the baseline. The monitored target software contains an agent for deriving a subset of measurements indicating the target software performance and activity. The agent includes sensors embedded into the target software to measure specific code segments, and an examiner which receives measurements from the sensors and transmits these examiner values to a central server. The central server automatically derives a baseline from the received examiner values, and automatically establishes a state of health of the target software based on comparing real-time measurements to the baseline.
