ABSTRACT:
A method and apparatus for allowing a troubleshooter to reuse existing indicators, such as displays, LEDs, or specialized indicators, for a purpose other than the indicator's usual purpose. In response to an initial occurrence of a problem, the troubleshooter modifies the indicator's behavior to indicate a later occurrence of a fault or a set of faults, which may be the cause of the problem. Upon the later occurrence of the problem, the indicator is monitored for simultaneous notification of occurrence of the fault. After the problem is triaged, the modified indicator is returned to its original use. The notification from the indicator can be sensory, i.e., auditory, visible, or tactile. The indicator's change in behavior can occur after the fault happens once or an administrable threshold number of times, or intermittently. Alternatively, the change in behavior may become semi-permanent if the fault continues to occur for some administrable number of times.
