In this paper, we address the problem of identifying periodically occurring patterns in a time series. The domain of data-center management is the primary focus. Data here comprises of request latencies, resource utilization of servers, data center workload etc. to name a few. Although periodicity detection has been researched, the past work does not(More)
This paper presents a simple, yet novel, approach to address the problem of spike detection. The definition of a spike varies with the domain under study. This results in domain-specific solutions that are often rendered unusable in other domains. Moreover, the spike detection algorithms proposed in the past are effective only when suitably tuned.
