1. GEMINI – A GENI Instrumentation and Measurement System Overview and Status

2. Current Status (Tutorial tomorrow)
To have an instrumentized slice:
1. Add a "GN" node to your rspec.
2. Run the instrumentize.py script with appropriate credentials and slice name.

6. Issues with current version
Multiple interfaces
Configuration confusion
perfSONAR services are specialized and hard to extend, many services for different metrics.
Different stores/databases for different metrics.
Old/Clunky SOAP and XML

7. New Architecture Features
New Measurement Store (MS)
NoSQL data store
Stores all metrics in a common (JSON) format
REST API
New UNIS
Also NoSQL/JSON
BLiPP (An MP)
Collects many host metrics and sends to MS
Registers metadata and config/status with UNIS

8. Next Steps Integration of ABAC support (prototyped)
Application metrics with NetLogger

9. Goals: High rate, low impact monitoring Single consistent interface
We want the ability to have very fine grained data.
Single consistent interface
We aim to simplify configuration while still leaving advanced options open
Fewer moving parts
Consolidated MS
UNIS unifies topology, configuration, and metadata
Easy processing, retrieval, and visualization of data
