Sponsored by the National Science Foundation5October 24, 2012 What’s Changed API called GMOC Objects –Makes it easier to report data to GMOC –Python module Use of URNs Aggregate Naming Support for Circuits

Sponsored by the National Science Foundation6October 24, 2012 GMOC Objects Models the state of things in GENI Loosely couples submission of metadata and time-series data Allows partial data submission Can be instantiated anywhere Much easier to use than previous solutions

Sponsored by the National Science Foundation15October 24, 2012 Future Directions? Populate the API with data from GMOC –Query current operational data about GENI things More measurements RSpec parser/generator –Monitoring extension Additional languages? Integration with Active Measurement projects Use Circuit data operationally

Sponsored by the National Science Foundation16October 24, 2012 GMOC Support for GENI Racks Campus/Racks Team contacts GMOC to announce Outage or upcoming Maintenance -Initially important to include very specific information (Campus, type of outage/maintenance, what’s affected, outage/maintenance times, who’s working to perform maintenance or resolving an outage, ETR, etc…) -Eventually through pro-active monitoring. -Contact GMOC as Racks come up.

Sponsored by the National Science Foundation17October 24, 2012 GMOC Support for GENI Racks GMOC tracks racks/campus events and notifies the GENI community: –Initially through the GENI Ops list and Ops Calendars (Web, RSS, iCal) –Long-term goal is to notify individual GENI Experimenters via targeted notifications based on which Aggregate is affected and slice ownership

Sponsored by the National Science Foundation18October 24, 2012 GMOC Operations Calendars

Sponsored by the National Science Foundation19October 24, 2012 Contact GMOC Phone: Website: GENI Ops Calendars (Web, RSS, iCal): c-operations-calendars.html c-operations-calendars.html GENI Bi-Weekly Operations Report: c-reports/gmoc-reports.html c-reports/gmoc-reports.html

Sponsored by the National Science Foundation20October 24, 2012 Some discussion questions… How meaningful are current notifications? How much does the GENI Community care about a single rack/campus outage? How important are notifications targeted to individual experimenters/operators? What else is important to the Community?
