1. A root cause analysis optimization method, comprising:

  • at a performance monitoring system, identifying a primary alarm metric and one or more probable cause metrics involved in producing a list of root cause analysis (RCA) candidates, wherein each of the RCA candidates is associated with an RCA score that indicates a level of correlation between each RCA candidate and the primary alarm metric;

    determining data points to use from the primary alarm metric and each probable cause metric based on an alarm time of the primary alarm metric;

    validating the data points between the primary alarm metric and each probable cause metric to remove discrepancies by aligning the data points in time to compute a correlation coefficient;

    applying a data correlation algorithm to the validated data points to compute the correlation coefficient between primary and secondary aligned data points;

    calculating a confidence factor by computing a data point ratio between the primary and secondary aligned data points using actual data points and theoretical data points;

    adjusting the level of correlation of the validated data points by adjusting the correlation coefficient using the confidence factor including the data point ratio;

    adjusting the RCA scores of the RCA candidates based on the computed correlation coefficient including using the adjusted correlation coefficient; and

    presenting to a user an optimized RCA candidate list listing a fraction of the RCA candidates sorted based the adjusted RCA score.
