Grid measurementsGrid measurements
Global Grid Forum• Areas:
• APME, ARCH, DATA, GRID SEC, ISP, P2P, SRM• Working / Research Groups
• GridFTP WG• Grid High-Performance Networking Research Group
(GHPN-RG)• Network Measurments Working Group (NM-WG)
NM-WG• Working Drafts, XML Schema...
GHPN-RG• Networking Issues, Use Cases• Path-oriented use case:
• HEP• Emergency Apps.
with Wireless Sensors
GHPN-RG• Knowledge-based use cases:
• collection and usage of network performance info
• Passively Monitored Data (like file-transfer usage)
• Administrative setup of Schedules of Measurements (network performance through triggered sessions)
• Service Optimization (user apps and middleware)
NetLogger• A Toolkit for Distributed System Performance
Tuning and Debugging
• Determine the source of performance problems with detailed end-to-end instrumentation
• timestamped event log• visualization
