A computer-implemented method includes receiving, by one or more sensors, data for one or more cycles, each of the one or more cycles including one or more slots. The computer-implemented method further includes combining the one or more slots from each of the one or more cycles into a combined slot group. The computer-implemented method further includes converting the combined slot group into a converted slot group. The computer-implemented method further includes monitoring the converted slot group for an anomaly. The computer-implemented method further includes, responsive to the anomaly: Comparing the anomaly to one or more known anomalies to determine a correlation between the anomaly and the one or more known anomalies, and determining the anomaly location. The computer-implemented method further includes reporting a problem condition based on at least one of the correlation and the anomaly location. A corresponding computer system and computer program product are also disclosed.
