Task 3.3 Grid Monitoring Subtask 3.3.2 SANTA-G

1. Task 3.3 Grid MonitoringSubtask 3.3.2 SANTA-G Brian Coghlan, Stuart Kenny Trinity College Dublin. Linz 2002, Task 3.3.2

2. Task 3.3.2 SANTA-G • Ad-hoc, non-invasive monitoring with external instruments. • Generic template. • Instruments could be anything! (e.g. fish sonars, PCR analysers). • CrossGrid Demonstrator: Network tracing • Use Case: Validation/Calibration/Optimisation of invasive monitoring tools. Linz 2002, Task 3.3.2

3. Network Tracing Node TCPDump Sensor RGMA pkts register data Trace Circular Queue Canonical Producer query data Network Tracing Instrument Linz 2002, Task 3.3.2

4. Network Tracing • TCPDump – Collects raw network trace data • Sensor – Collects data and stores in circular queue • Sensor – Makes data available through R-GMA by creating Canonical Producers. • Canonical Producer – New form of R-GMA Producer from TCD. • R-GMA: the DataGrid information system Linz 2002, Task 3.3.2

5. Use Case RGMA query R-GMA Consumers Non-Invasive DataSet data data query data Network Tracer Validation/ Calibration Optimisation pkts Monitored Component Invasive Tool Invasive DataSet data data Linz 2002, Task 3.3.2

6. Use Case • R-GMA Consumers – Any form of R-GMA consumer (e.g. ConsumerProducer) • Invasive tool – Any form of invasive monitoring tool (e.g. OCM-G) • Validation/Calibration: • Compare data – validation • Mismatch – calibration • Optimisation Linz 2002, Task 3.3.2
