Abstract

The invention discloses a distributed system fault source diagnosis method. The method comprises the following steps: constructing a call graph of a distributed system; and based on the call graph, searching the fault source. According to the method, the abnormal propagation graph is automatically constructed, and the process of manually searching the abnormal root is simulated through the randomwalk algorithm, so that the human error is reduced, the operation and maintenance troubleshooting time is shortened, the fault solving efficiency is improved, and the online overall operation and maintenance quality is improved.

Description

technical field [0001] The invention relates to the technical field of computer science software information, and specifically relates to a method for diagnosing root causes of faults in distributed systems. Background technique [0002] A distributed system is a software system that supports distributed processing, and it is a system that executes tasks on a multi-processor architecture interconnected by a communication network. It includes distributed operating system, distributed programming language and its compilation (interpretation) system, distributed file system and distributed database system, etc. The failure of a distributed system will occur on various modules. [0003] For distributed systems, when manually diagnosing the root cause of a fault, the operation and maintenance engineer often checks the system based on the module call relationship diagram in his mind. Many times, the failure is discovered because of seeing many failed requests on the most upstrea...
