Method, system, first network device and third network device for obtaining log

Abstract

The invention discloses a log obtaining method, a log obtaining system, a third network device and a first network device; the log obtaining system is characterized by comprising the first network device, a second network device and the third network device, wherein the second network device sends an early warning message; the first network device receives the early warning message sent by the second network device; the first network device sends a log backup command to the third network device; the third network device receives the log backup command sent by the first network device, and backups a log according to the log backup command when determining the log backup command meets the requirements; the third network device sends the backup log to the first network device; and the first network device receives the backup log sent by the third network device. The log obtaining method, the log obtaining system, the third network device and the first network device are used for improving the log obtaining efficiency, thereby realizing the positioning analysis to a fault and improving the efficiency.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method and system for obtaining logs, a first network device and a third network device. Background technique [0002] In the field of computer technology, with the continuous development of communication technology and the increasing number of network devices, it is necessary to debug the network devices in many cases to determine the cause of abnormal network traffic and ensure that users can access the network normally. [0003] Generally, a network device will monitor the running network device during operation, and the monitoring result can be recorded in a log corresponding to the running network device. In the log, the running status of the running network device, the network traffic of the network, and the corresponding log recording time can be recorded. Afterwards, by analyzing the logs, it is possible to debug the network device, determine the cau...

Problems solved by technology

[0004] However, the storage space of network devices is limited, and the abnormality of running network devices is random. It is possible that when a running network device is abnormal, the running network device will correspond to a large number of logs, and the relevant logs will be checked. During the analysis, the number of logs to be analyzed is relatively large, and it is necessary to filter among many logs, which is not conducive to quickly determining the required logs among the many logs. In addition, it is more efficient to determine the logs related to the abnormal state in a large number of logs. Low
