Grid monitoring system is differentiated from a general monitoring system in that it must be scalable across wide-area networks, include a large number of heterogeneous resources, and be integrated with other Grid middleware in terms of naming and security issues. Grid Monitoring is the act of collecting information concerning the characteristics and status of resources of interest. We propose grid monitoring system that is based on the Grid Monitoring Architecture (GMA). The GMA specification sets out the requirements and constraints of any implementation. It is based on simple Consumer/Producer architecture with an integrated system registry and distinguishes transmission of monitoring data and data discovery logically. The proposed grid monitoring system consists of producers, registry, consumers, and failover registry. The registry is used to match the consumer with one or more producers, so it is the main monitoring tool. The failover registry is used to recover any failure in the main registry in every domain. The structure of proposed grid monitoring system depends on java Servlet and SQL query language. This makes the system more flexible and scalable. The security and efficiency are also achieved by the proposed grid monitoring system. We evaluate the performance of it by measuring the overhead, the response time, and CPU utilization. All results introduce better performance, but the system needs more load balancing.
