Abstract
A method for accurately tracking fault status in a computer system. The method includes storing a prior state for a sensor associated with a component of the computer system and receiving a sensor reading. When the prior state indicates the sensor was unavailable or unreadable such as when the component was removed, the method includes resending or re-emitting a faulty event to the fault diagnosing module, e.g., after reinsertion of the component in the computer system while it is still faulty. The method may include, prior to the triggering of the resending of the faulty event, determining that the sensor is in a non-nominal state. The method may also include storing in the data storage a definition of a nominal state for the sensor such that the determining the sensor is in the non-nominal state includes comparing one or more sensor readings with the nominal state definition.
