Grid Monitoring and Management
A dedicated Grid monitoring and management centre at C-DAC, Bangalore helps in managing and monitoring all the components in the Grid. Monitoring health and utilization of various components of the Grid is an essential task. A mobile agent framework for monitoring the Grid resources and also for automatic update of software releases may be beneficial for monitoring an entire production grid. Grid monitoring involves measuring grid resource parameters, to analyze usage, availability, behaviour and the performance. Its objectives include:
Performance is one of the major concerns in grid environment. The performance of each of the service / resource needs to be analyzed and problems reported. Grid performance at all levels machine, network, cluster, VO etc should be extensively investigated.
- Locating performance problems
- Tuning for better performance
- Fault detection and recovery
- Input to prediction services
- Input to scheduler services
Performance analysis is important to implement the QoS of grid service. The monitored data is useful to generate metrics and trust calculation of various combinations of components of the dynamic grid infrastructure. It will provide intelligent means to ensure QoS adhering to SLAs. Algorithm/mathematical model (like State space model) can be used to calculate the queue length, total no of jobs in the system, throughput of the system, response time of job request etc.
A dedicated Grid Monitoring and management centre at C-DAC Bangalore helps in managing and monitoring all the components in the Grid. State -of –the-art display walls and advanced software like “Paryavekshanam” developed at C-DAC, helps in effectively monitoring the health and utilization of various components of the Grid. Paryavekshanam provides different viewing ability based on user credential like administrator or general user.
