Problems solved by technology

[0003] In the prior art, in order to measure the performance of a distributed system under failures, failures at the server cluster level are usually simulated, and such failures are likely to have a great impact on the real business environment
In order to avoid such a large impact, it is necessary to build a test environment isolated from the real business environment to simulate faults. On the one hand, this requires a large operation and maintenance cost. On the other hand, fault simulation is performed in an isolated test environment. The obtained performance results of the system are not necessarily consistent with the real results of the system in the real business environment, which is not conducive to obtaining a feasible solution to the actual fault

Embodiment Construction

[0028] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0029] The term "computer equipment" in this context, also referred to as "computer", refers to an intelligent electronic device that can perform predetermined processing procedures such as numerical calculations and / or logic calculations by running predetermined programs or instructions, which may include a processor and The memory is realized by the processor...

Abstract

The invention provides a system of carrying out fault simulation in a distributed system, an apparatus and a method thereof. The method comprises the following steps of receiving an access request; from the received access request, screening a specific access request according with a predetermined fault simulation rule; and aiming at the specific access request, carrying out fault simulation in the distributed system. By using the method and the apparatus of the invention, a fault influence range can be effectively controlled; and because the method and the apparatus can be directly implemented in an actual service environment, operation cost generated during independent test environment construction can be effectively saved.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a system, device and method for fault simulation in a distributed system. Background technique [0002] A distributed system usually includes multiple application components (or multiple subsystems), and some application components often fail. In order to solve these faults, the existing technology usually simulates some faults in an independent test environment, so as to determine the solution to the simulated fault by measuring the performance of the distributed system under the simulated fault, so that the solution can be used to solve the real business failures in the environment. [0003] In the prior art, in order to measure the performance of a distributed system under failures, failures at the server cluster level are usually simulated, and such failures tend to have a great impact on real business environments. In order to avoid such a large impact, it is necessa...
