Abstract:
1. A computer implemented method for identifying relevant metrics, the method comprising: a computer processor configured to perform: selecting, for each pair of individual service metrics in a plurality of individual service metrics, at least a first set of points representing a given number of measurements for a first individual service metric in the pair of individual service metrics; selecting a second set of points representing a given number of measurements for a second individual service metric in the pair of individual service metrics; setting a first threshold value for the first set of points; setting a second threshold value for the second set of points, whereby the first threshold value and the second threshold value are selected to produce a set of quadrants that maximizes a distribution of points of an intersection of the first set of points and the second set of points between at least one of a group comprising a second quadrant and a fourth quadrant and a group comprising a first quadrant and a third quadrant; determining, based on the first threshold value and the second threshold value, a highest amount of mutual information value between the first and second individual service metrics; creating a matrix comprising at least two axes that intersect, where a first and second axis each comprises a series of individual service metrics from the plurality of individual service metrics, wherein each pair of intersecting individual service metrics from the first and second axes comprises the highest amount of mutual information value between the individual service metrics from the first and second axes; comparing, for each pair of intersecting individual service metrics, the highest amount of mutual information value to a threshold; identifying, in response to the highest amount of mutual information value exceeding the threshold, the pair of intersecting individual service metrics as a set of relevant metrics; and removing, in response to identifying the pair of intersecting individual service metrics as a set of relevant metrics, at least one individual service metric from the pair of intersecting service metrics.
