Abstract: Methods, systems and computer program products for detecting a workload imbalance in a dynamically scheduled cluster of computer servers are disclosed. One such method comprises the steps of monitoring a plurality of metrics at each of the computer servers, detecting change points in the plurality of metrics, generating alarm points based on the detected change points, correlating the alarm points and identifying, based on an outcome of the correlation, one or more of the computer servers causing a workload imbalance. Systems and computer program products for practicing the above method are also disclosed.
