Enabling Grids for E-sciencE

EGEE-II INFSO-RI-031688

Core Concepts

• Monitor EGEE compatible information systems • Primary goals for GStat:

– Detect faults in the information system– Validates the information content– Displays useful information with different views

• Build a sustainable architecture– Enabling decentralized operations – In a federated environment

• Redesign GStat in modular way– Reusable components – Multi-location (site/roc)– Multi-application (certification/operations)

Component Descriptions

• Core– Provides an SQL DB snapshot of the BDII content– Maintains an entity cache of what has been seen

• Validation– Validates the information content– Provides testing results for visualization or export

• Monitoring– Detects faults in the information system– Entity DB is used to configure which entities are monitored– Prepares monitoring data and graphs ready for visualization

• Visualization– Uses entity DB to generate the main structure– Visualizes the result of validation and monitoring– Provides different views for different user groups
