Challenges of monitoring tool for operational indian national grid GARUDA

摘要

Computational grid involves the sharing of dynamic and geographically distributed heterogeneous resources to cater to highend scientific problems. The dynamic nature of grid makes monitoring and maintenance of grid health a challenging task. Grid monitoring is a central part of grid as it functions as the dynamic information repository for both system administrators and developers for status checking, troubleshooting, scheduling, performance tuning and analysis. We have developed and deployed a grid-monitoring tool to monitor Indian national grid “GARUDA”. The unique features of it are monitoring network and computational resources, grid middleware, jobs, storage, softwares, and special scientific instruments. It also captures the service degradations of resources and notifies for corrective actions.
