Implementation of Monitoring and Information Service Using Ganglia and NWS for Grid Resource Brokers

Grid computing is increasingly used by organizations to achieve high performance computing and heterogeneous resources sharing. These grids may span several domain administrations via Internet. As a result of this, it may be difficult to monitor, control and manage those machines and resources. This paper aims at providing a multi-platform grid monitoring service which can monitor resources such as CPU speed and utilization, memory usage, disk usage, and network bandwidth in a real-time manner. Monitoring data is extracted form Ganglia and NWS tools then stored and transmitted in XML form and then used for displaying. All the information is displayed using real-time graphs.
