Embodiment Construction

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

[0040] In order to better understand the embodiment of the present application, the communication system to which the embodiment of the present application is applicable is described below.

[0041] figure 1 It is a schematic diagram of a communication system provided by an embodiment of this application. Such as figure 1 As shown, the communication system includes a memory anomaly detection device and at least one first device. Communication can be performed between the memory anomaly detection device and the first device. Wherein, a memory log is stored in the first device. The first device may be a software-defined network (softwaredefined network, SDN) controller, a log server, or a router, and other devices that store memory logs. The first device and the memory anomaly detection device may be deployed in the same dev...

Abstract

A memory anomaly detection method and apparatus are disclosed in embodiments of that present application. The method comprises the following steps: acquiring a first memory log, wherein the first memory log comprises log information of garbage collection for a plurality of times, the log information of each garbage collection comprises garbage collection time, and at least one of a downtime, a memory occupancy rate after garbage collection and a memory occupancy rate before garbage collection; obtaining the first statistical information corresponding to the first detection time window according to the log information in the first detection time window; the degree of abnormality corresponding to the log information in the first detection time window is determined according to the first statistical information corresponding to the first detection time window. As can be seen, by implementing the method described in the embodiments of the present application, the accuracy of the memory anomaly degree detection result is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a memory abnormality detection method and device. Background technique [0002] Generally, if a memory abnormality occurs in a network device, it is easy to cause a failure of the network device, thereby affecting the network. For example, a memory leak is a type of memory exception. A memory leak refers to the heap memory that has been dynamically allocated in the program is not released or cannot be released for some reason, resulting in a waste of system memory, resulting in serious consequences such as slowing down the running speed of the program or even system crashes. [0003] For example, memory anomalies are particularly severe in software defined network (SDN) controllers. The SDN controller is the "brain" of the network and is the application responsible for strategic control in the SDN network. Since the SDN controller stores all the informatio...
