Research And Implementation Of Business Service Monitoring System Based On Nagios

As current enterprise IT systems are becoming more complex and the numbers of network devices, servers and databases are increasing quickly, there is a significant gap between domestic enterprises on the operation of the IT infrastructure monitoring, and it is urgent to need a complete set of standards, a unified monitoring system operation of IT infrastructure monitoring to help improve the level of IT systems management.At the same time, the business department has introduced a variety of new business systems, and the system maintenance workload has grown significantly. If a business system is running fails, the business department could not determine the specific cause of fault, IT departments due to the lack of understanding of the business system, could not determine the impact of the failure of the business.
