Problems solved by technology

After the node dies, if it cannot be identified effectively and timely, it will seriously affect the stability and performance of the entire cluster, and will cause the upper-layer application to be temporarily unavailable
However, it is difficult to detect the false dead node. If the method is wrong, it will be misjudged

Abstract

The embodiment of the invention provides a monitoring method, device and system for the working state of nodes in a distributed cluster system. The monitoring method for the working state of the nodes in the distributed cluster system comprises the steps that the times number that each node in the distributed cluster system is judged as heartbeat detection timeout by the other nodes in a predetermined time is acquired; the node with the largest times number is selected from the nodes; the network connection state of the selected node is acquired; when the network connection state of the selected node is a smooth state, the selected node is judged as a suspended animation node; and when the network connection state of the selected node is a disconnected state, a judgment result that the selected node is a real death node is generated. According to the monitoring method, device and system, the suspended animation node can be effectively, reliably and quickly recognized in time, and therefore the cluster stability is improved.

Description

technical field [0001] The invention relates to the field of distributed systems, in particular to a method, device and system for monitoring the working status of nodes in a distributed cluster system. Background technique [0002] With the wide application of cloud computing in various fields and the increase of data volume, there are high demands on the scale, performance and reliability of distributed file systems. In large-scale clusters, small-probability events will become more frequent. Node suspended animation is one of the problems that needs to be solved. After a node dies, if it cannot be identified effectively and in a timely manner, it will seriously affect the stability and performance of the entire cluster, and will cause temporary unavailability of upper-layer applications. However, it is difficult to detect the false dead node, and if the method is wrong, it will be misjudged. Contents of the invention [0003] Embodiments of the present invention prov...
