Detecting Unhealthy Cloud System Status

摘要

In this paper, in order to detect the unhealthy status in the cloud system, a Basic Detection Strategy and a Threshold Strategy based on mathematic theory and statistical knowledge is proposed to solve this problem. By introducing unhealthy status percentage parameter α, both Basic Detection Strategy and Threshold Strategy are combined to detect and monitor the unhealthy cloud system status. For illustration, an eBay company example is utilized to show the feasibility of Basic Detection Strategy and Threshold Strategy. Empirical results show that Basic Detection Strategy with setting a suitable value to α can pinpoint most of unhealthy status in the cloud system, however, for some special unhealthy status, it must adopt the Threshold Strategy to pinpoint. The combination of Basic Detection Strategy and Threshold Strategy can effectively detect and pinpoint the unhealthy status in the cloud system and help staff to improve the performance of cloud system.
