1. GEMINI Indiana University, University of Kentucky

2. Overview Combine U. Kentucky’s INSTOOLS, perfSONAR and Periscope Support scalable, high-rate measurement across layers – Including infrastructure

3. Measurement Points Produce measurement data Send data to a Measurement Store Send metadata to UNIS Standard perfSONAR and INSTOOLS MPs BLiPP (Basic Lightweight Periscope Probes) – High rate host monitoring – Adjustable frequency NetLogger and Calipers for application monitoring – Addressing scalability with in-line analysis and summarization – Example: system call monitoring to determine file transfer bottleneck

4. Measurement Store Stores Measurement data (I know you didn’t see that coming) Supports high-rate data transfers Publish/Subscribe interface Multiple tiers with different characteristics – Surge tank near the source – Bottom of rack – Parallel storage for slice-wide data

5. MAP Measurement/Management and/Analysis Presentation Service Configuration GUI Visualize data (from MS) Visualize topology (obtained from UNIS)

6. Portal “One stop shop” to integrate various MAP services

7. MC Measurement controller/coordinator Initiates measurement collection Coordinates measurements Fetches data from some MPs

8. UNIS Directory service Topology data – As well as changes Service data Measurement metadata

9. Cross cutting RESTful interface to perfSONAR (Periscope) GEMINI Event Messaging Service (GEMS) – High rate data with JSON/BSON
