Service monitoring method and system for cloud service infrastructure

The invention provides a service monitoring method and system for cloud service infrastructure, and belongs to the field of the cloud service infrastructure. The system comprises a control center server and dialing test servers arranged in regions. Cloud service dialing modules are arranged on the dialing test servers, and a dialing test task issuing module, a data collection module, a dialing test data analysis module, a dialing test alarm module and a database are arranged on the control center server; and the dialing test servers are arranged in different regions, a monitoring task is configured on a WEB interface of the control center server, the dialing test task issuing module issues a configuration file of the monitoring task to each dialing test server to verify the correctness ofa destination IP of the task, a wide-range asynchronous dialing test monitoring method is adopted, the monitoring of the cloud service infrastructure is implemented for routers and DNS recursive servers that provide services,
