Embodiment Construction

[0039] Specific embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0040] For a better understanding of the embodiments of the present application, the following embodiments may be applied to the communication system of the embodiment of the present application will be described.

[0041] figure 1 Used in this application is a schematic diagram of a communication system according to an embodiment. like figure 1 Shown, the communication system comprises a memory device and at least one abnormality detection device first. It may be in communication between the memory device and the first abnormality detecting device. Wherein the first memory device stores a log. The first device may (softwaredefined network, SDN) controller, or the like log server router stores a log memory device as software-defined network. A first memory device and the abnormality detecting apparatus can be deployed in the same device...

Abstract

The embodiment of the present application discloses a memory abnormality detection method and device, wherein the method includes: obtaining a first memory log, the first memory log includes log information of multiple garbage collections, and the log information of each garbage collection includes garbage Recycling time, and including at least one of downtime, memory occupancy rate after garbage collection, and memory occupancy rate before garbage collection; according to the log information in the first detection time window, the first time window corresponding to the first detection time window is obtained. Statistical information: according to the first statistical information corresponding to the first detection time window, determine the degree of abnormality corresponding to the log information in the first detection time window. It can be seen that by implementing the method described in the embodiment of the present application, the accuracy of the memory abnormality detection result is improved.

Description

Technical field [0001] The present application relates to communication technologies, and particularly to a method and apparatus for detecting abnormality of memory. Background technique [0002] Typically, the network memory devices if anomalies occur, it is very easily lead to network equipment failure, thereby affecting the network. For example, memory leaks is a memory exception. A memory leak means that the program has been dynamically allocated heap memory for some reason the program does not release or not release, resulting in a waste of system memory, resulting in a program run slower and even system crashes and other serious consequences. [0003] For example, memory exception is particularly serious software-defined network (software defined network, SDN) controller. SDN network controller is the "brain", is responsible for strategic control of SDN network applications. Since SDN and stored in the controller itself has almost all of the information, memory leaks and ot...
