1. An error logging and analysis system, comprising:

  • an error detection unit;

    an error logging device; and

    an error analysis unit;

    wherein, within a period of time, the error detection unit is adapted to detect a first occurrence of a particular type of fault condition, the error detection unit is adapted to determine a first time of the first occurrence, the error detection unit is adapted to assign an initial error severity weight to the first occurrence, the error logging device is adapted to record the first time and the initial error severity weight, the error detection unit is adapted to detect a second occurrence of the particular type of fault condition, the error detection unit is adapted to determine a second time of the second occurrence, the error logging device is adapted to record the second time, the error analysis unit is adapted to determine a first interval between the first occurrence and the second occurrence, the error analysis unit is adapted to generate a first error frequency factor related to the first interval, the error analysis unit is adapted to generate a first weighted error rate that is a first function of the initial error severity weight and the first error frequency factor.
