GIMI I&M and Monitoring Mike Zink University of Massachusetts Amherst GEC 15, Houston, October 23 rd 1

Overview Introduction Goals GIMI and ExoGENI, iRODS, IREEL Tutorial Monitoring Next steps 2

Introduction Develop and deploy the GIMI instrumentation and measurement framework Capable of supporting needs of GENI experimenters and GENI infrastructure operators Uses OMF/OML and integrated Rule Oriented Data System (iRODS) as its basis Will provide libraries to instrument resources, to filter and process measurement flows, and to consume measurement flows It will use the iRODS data grid for archiving and further processing Will include access control based on accepted GENI policy and authorization mechanisms 3

Goals Provide easy-to-use I&M services for experimenters: deploying slices in GENI on selected types of servers, VMs and racks, WiMAX installation, and sensor networks. interconnected by various types of network paths Provide comprehensive infrastructure measurement services for infrastructure operators: deploying measurement slices on selected types of servers, VMs and racks, and WiMAX installations interconnected by a various types of network paths In addition slices established by other infrastructure operators, or by experimenters, can be authorized to gather data from the measurement slices 4

Goals This project will build and operate two persistent services: the GENI Measurement Data Archive Service (i.e., iRODs) and the GENI Experimenter Portal Service Collaborate with existing I&M Spiral 2 projects and GEMINI 5

GIMI and ExoGENI GIMI and ExoGENI integration: – ExoGENI image with GIMI tools publicly available – Process to automatically set up measurement while acquiring resources Client tools in GIMI user workspace Will be major part of today’s tutorial 6

GIMI and iRODS Measurement data is automatically stored in iRODS by OML server Metadata is automatically add and can be manually augmented Users can store and retrieve measurement data in iRODS iRODS client in GIMI user workspace 7

Monitoring Passive monitoring of slice is possible with GIMI tools Include OMF/OML tools in basic ExoGENI image E.g., nmetrics could be reported to monitoring service. Experiment scripts run by monitoring service Measurement data collection run by monitoring service. 13

Next Steps Monitoring support (from GEC14) – Access control? – What will be monitored? Additional questions: – How will monitoring data impact actual measurement? 14
