Cluster node health status early warning method and system

Abstract

The application discloses a cluster node health status early warning method which comprises the steps that: a monitoring module of each node acquires health status data of the node; a monitoring management module acquires the health status data, sends the health status data and a node identifier of the node to an early warning module; the monitoring management module and the early warning module are deployed on a management node; the early warning module judges whether the health status data accords with preset conditions in an early warning configuration file; and if no, a node generation early warning event corresponding to the node identifier of the node is determined, the early warning event is added into an early warning notification queue, and early warning notification is carried out. According to the cluster node health status early warning method disclosed by the application, by utilizing the monitoring management module and the early warning module which are deployed on the management node, early warning notification can be carried out when the node is abnormal; and deployment work of the early warning module and modification work of the early warning configuration file are simplified, so that operation cost of a system is reduced. The application further discloses a cluster node health status early warning system which also has the beneficial effects above.

Description

technical field [0001] The present application relates to the field of cluster technology, in particular to a method and system for early warning of the health status of cluster nodes. Background technique [0002] With the development of information technology, cluster technology, as a new technology, has shown its talents in computing-intensive applications such as weather forecasting and nuclear test simulation. It can not only greatly improve the computing performance of the system, but also enhance the reliability of the system. [0003] Specifically, a cluster refers to a group of service entities such as computers that are independent of each other and interconnected through a high-speed network. Each service entity in the cluster is a node. These nodes form a group to provide services to the outside world, and have higher expansion than a single service entity. performance, usability. [0004] Since a cluster generally contains multiple nodes, it is necessary to mon...

Problems solved by technology

[0006] However, since the early warning module is deployed in each node in the cluster in the prior art, the technical solution provided by the prior art cannot avoid the disadvantage of cumbersome deployment

In addition, since each node in the cluster is equipped with an early warning module, when the application system needs to modify the early warning mechanism of the node health status, it is necessary to modify the relevant data of the early warning configuration file in each node one by one, which is also very cumbersome
