Problems solved by technology
[0003] The inventors have found through research that in the prior art, when a certain management node or ordinary managed node of the distributed management system fails, other corresponding nodes in the system can still replace the work, making it difficult for technicians to find the system The node in the middle is already in the fault state, and the problem cannot be found and solved in time, resulting in damage to the actual function of the system

The present invention provides a node fault detection method, comprising: obtaining the IP address of each node; judging whether each node satisfies a preset detection condition based on the IP address of each node; determining the node that satisfies the detection condition be the target node; send a detection instruction to each of the target nodes, and obtain the detection information generated by each of the target nodes according to the detection instruction; judge whether there is an abnormality mark in each of the detection information, and record the presence of the abnormality mark The node corresponding to the detection information is determined as a faulty node. By applying the method provided by the embodiment of the present invention, it is possible to send detection instructions to each node, obtain the detection information generated by each node according to the detection instruction, and judge whether the detection information has an abnormal mark, so as to determine the node corresponding to the detection information Whether there is a fault, the node in the system that has been in a fault state can be quickly discovered.
Description
technical field [0001] The invention relates to the field of distributed systems, in particular to a node failure detection method and device. Background technique [0002] With the development of information technology, distributed systems occupy a pivotal position in the Internet field. In the distributed management software of distributed systems, multiple management nodes usually form multiple peer-to-peer management clusters. Among them, the management nodes can Manage the common managed nodes in the corresponding management cluster. During the operation of the system, each management node and each common managed node can cooperate with each other to achieve high availability of the entire system. [0003] The inventors have found through research that in the prior art, when a certain management node or ordinary managed node of the distributed management system fails, other corresponding nodes in the system can still replace the work, making it difficult for technicians...
