1. A method, comprising: monitoring a plurality of services; collecting performance data for each service included in the plurality of services; identifying, by operation of one or more computer processors, a cluster of related services by analyzing the performance data and determining that each service included in the cluster of related services exhibits a statistically similar pattern of performance data with respect to one or more performance metrics, wherein a first service is included in the cluster of related services, by: calculating a similarity value for at least one service included in the plurality of services that is indicative of a statistical similarity between the performance data of the service and at least one of the performance data of the first service, the performance data of a second service, and a predetermined statistical pattern, and determining that the similarity values calculated for each service included in the cluster of related services exceed a predetermined threshold amount of similarity; and determining, by operation of one or more computer processors, that the first service is a root cause of the pattern of performance data for each service included in the cluster of related services by determining that each service included in the cluster of related services, other than the first service, depends, either directly or indirectly, on the first service.
