  Abstract

We need a system to efficiently analyze the cause of failure of edge cloud system that provides service at a location close to subscribers. When applying the method applied to the existing single cloud system to the central cloud and applying it to the analysis of the failure cause of the multiple edge cloud systems at the remote site, the traffic for event reporting from each component in the multiple individual edge clouds is distributed to the central cloud which may cause a problem in real time fault reporting. In this paper, the resource status of each edge cloud is collected locally at each edge, collected as information related to each other, and transmitted to the central cloud to reduce the traffic caused by the information request message for tree configuration from the center to the edge. We propose a method to apply the fault correlation tree received from the edge to the existing fault analysis system by constructing a hierarchical fault tree as the center. The proposed scheme is implemented based on Vitrage, which is a project to analyze the existing failure cause of openstack, to verify that Root Cause Analysis(RCA) can be efficiently performed while reducing the traffic from the central cloud to the edge cloud. Experimental results show that the proposed scheme is effective by comparing the total amount of RCA tree construction time with the amount of request message traffic delivered from the center to the edge between the proposed structure and the simple RCA applied method.
