  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
