“…In the end, this hidden complexity has been the cause of many performance problems (Altendorf et al, 2002;Cecchet, Marguerite, & Zwaenepoel, 2002;Noel, 2005). This motivated research and development of a myriad of approaches for easing the task of diagnosing and solving performance problems (Dinker & Schwetman, 2006;Dudney, Asbury, Krozak, & Wittkopf, 2003;Haines, 2006;Kounev & Buchmann, 2002;Rossi & Turrini, 2005;Shuf & Steiner, 2007;Stylianou, Ferrari, & Ezhilchelvan, 2007;Tselikis, Mitropoulos, & Douligeris, 2007;Zadrozny, Aston, & Osborne, 2003) in enterprise distributed systems. One line of efforts proposes to predict the performance of a system by modeling its components and interactions under different synthetic load scenarios (Chen, Gorton, Liu, & Liu, 2005;Kounev, 2006;Liu, Fekete, & Gordon, 2005).…”
