System performance monitoring system

A performance monitoring system comprising:

• a plurality of detectors operatively associated with locations on a display of a system being monitored;
• a controller configured to receive a first input from at least one of the plurality of detectors and indicative of an event at the location associated with the at least one detector and a second input indicative of a signal from the system being monitored to the display to generate the event at the optical output;
• and
• wherein the controller and the detector operate without modification of the system being monitored.

A method of determining performance of a system comprising the steps of:

• A. operating a system under test configured to monitor a device and provide an output signal indicative of a condition of the device;
• B. displaying the output signal;
• C. connecting a test management system to the system under test to monitor operation of the system under test without interfering with operation of the system under test;
• D. confirming the display of the output signal;
• and
• E. comparing the confirmation of the display of the output signal and an instruction to generate the display of the output signal.
