Abstract—One of the key factors in customer satisfaction is application performance. To be able to guarantee good performance, it is necessary to take appropriate measures before a server overload occurs. While in small systems it is usually possible to predict server overload using a subjective human expert, an automated overload prediction mechanism is important for ultra-large scale systems, such as multi-tenant Software-as-a-Service (SaaS) systems. An automated prediction mechanism would be an initial step towards self-adaptiveness of such systems, a property which leads to less human intervention during maintenance, resulting in less errors and better quality of service. In order to provide such a prediction mechanism, it is important to have a solid overload detection approach, which is (1) a first step towards automated prediction and (2) necessary
