US Patent 10291463 Large-scale distributed correlation

Disclosed herein are system, method, and computer program product embodiments for performing distributed correlation to determine a probable cause for a performance problem detected in an application. An embodiment operates by triggering an alert for a performance metric of an application executing on a local-level node. The alert may be sent to a higher-level node. Upon receiving the alert, the higher-level node may send a distributed correlation request, used to determine a root cause of the alert, to the lower-level node. Upon receiving the distributed correlation request, the lower-level node may produce and send a correlation result to the higher-level node. Upon receiving the correlation result, the higher-level node may select the probable cause of triggering the alert based on the correlation result. The probable cause may then be presented to the user.
