A state monitoring method and its device, data center and multi-active data center

Abstract

The invention discloses a state monitoring device. The state monitoring device comprises a plurality of internal monitoring equipment which correspond to each network layer one by one and global monitoring equipment; each internal monitoring equipment is used for periodically obtaining IP (Internet Protocol) information and state information of each server in the corresponding network layer, and sending the information to the global monitoring equipment; the global monitoring equipment is used for periodically analyzing a working state of each business system according to the received IP information and state information and a pre-set health judgment strategy, selectively setting the business systems to available and unavailable states according to analyzing results and sharing state conditions of all the business systems to a multi-active data center or the global monitoring equipment of other data centers in the bi-active data center. According to the state monitoring device provided by the invention, a condition that businesses have faults, caused by the fact that the business systems are abnormal, can be reduced, the user experience is improved and the reliability is high; the invention further discloses a state monitoring method, the data center comprising the state monitoring device and the multi-active data center.

Description

technical field [0001] The invention relates to the technical field of data center access, in particular to a state monitoring method and device thereof. The invention also relates to a data center and a multi-active data center. Background technique [0002] The multi-active data center mainly provides application services to the outside world by building multiple data centers at the same time. Each data center uses several other data centers as backups, which can avoid business interruption (or long-term interruption) when a data center fails. ). The data center generally provides external services through the DNS domain name. When the client accesses the service, it will first initiate a DNS query request to the local data center. When the DNS server in the local data center is responsible for parsing the DNS The scheduling strategy selects a business server in a suitable data center from multiple data centers, returns its IP information to the client, and the client in...

AI Technical Summary

Problems solved by technology

In order to ensure the normal operation of the data center, there is a global monitoring device in the data center, but the existing global monitoring device can only monitor the status of the server at the WEB layer, but cannot monitor the status of servers in other network layers inside the data center. When the WEB layer server is normal, but the servers in other network layers are abnormal, the user’s DNS query request may still choose the current data center for access, resulting in user business errors and reducing user experience
