Stability-As-A-Service is critical for data centers and workload characterization is one of the essential services within Stability-As-A Service. Different solutions have been proposed in the past for characterizing various system properties, however most of these approaches often require high levels of instrumentation and intrusiveness. This makes their use difficult in real-world production systems. In this paper, the authors argue that many interesting insights can be derived to characterize system workload simply by analyzing the transaction logs captured at different layers in the system such as access logs at application servers, SQL logs at database servers, among others.
