Fault diagnosis method, device and server

Abstract

The invention provides a fault diagnosis method, a fault diagnosis device and a server. The fault diagnosis method comprises the following steps: establishing topology of a network system; obtaining alarm information in a network system; associating the alarm information with nodes in the topology, and determining a fault link; and determining a fault root node in the fault link according to a preset fault probability calculation rule. According to the method, the fault link is determined by associating the alarm information with the topology of the network system, so that the service influence range and degree caused by the alarm can be quickly obtained, the fault root node is determined in the fault link according to the preset rule, the automatic positioning and accurate positioning ofthe fault are realized, and the fault processing efficiency is improved.

Description

technical field [0001] The invention relates to network technology, in particular to a fault diagnosis method, device and server. Background technique [0002] In various network systems, there are a large number of different types of network devices. When a network device fails, an alarm message will be generated. Maintenance personnel can view the alarm message to find out the faults in the system in time and deal with them. [0003] In the existing alarm processing system, each time an alarm is generated on each device, an alarm message of the device is usually sent. If there are frequent alarms on each device due to repeated reasons, multiple repeated alarms are combined and sent to the device. warning information. [0004] For a network system with a complex structure and a large number of devices, since the alarm information sent by each device is not related to each other, it is impossible to determine the operation status of other devices associated with the device ...

Problems solved by technology

[0004] For a network system with a complex structure and a large number of devices, since the alarm information sent by each device is not related to each other, it is impossible to determine the operation status of other devices associated with the device through the alarm information of a device. When locating a fault, it is often necessary to check a large number of alarm information of multiple devices to determine the root cause of the fault, which is relatively inefficient
