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.

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
