This document outlines the key discussions and technical aspects of the GGUS (Grid Governance User Support) operations model as presented by Torsten Antoni during the SA1 face-to-face meeting held in Abingdon on December 3, 2008. It addresses challenges related to scalability, standardization, and the necessary shift towards messaging systems to improve communication and support across regional and central coordination units. It also presents future plans, including the interface with GOCDB and the evaluation of messaging platforms as a communication tool within the grid infrastructure.

  5. GGUS operations model (technical) • user support model regional (almost) from the beginning • regional help desks • give support to sites • provide uplink to central coordination • Main concern is scalability from ROCs to NGIs • increasing number of interfaces • need for standardisation • moving to messaging could provide the solution • needed in other areas anyway • Correlation with COD model and OAT work • Middleware support: https://twiki.cern.ch/twiki/bin/view/EGEE/Egee3Jra1Support SA1 face-to-face meeting - Abingdon 03/12/2008 - Torsten Antoni

  10. Summary of ‘old’ new features SA1 face-to-face meeting - Abingdon 03/12/2008 - Torsten Antoni

  11. Expansion of direct routing • During EGEE’08 discussion on how to enable the extension of Team Tickets also to Tier-2 sites • Proposed solution: Interface between GOCDB and GGUS to allow retrieval of site names and contacts • Proposal to open up the direct ticket routing mechanism (as being used for the Alarm and Team Tickets) to ALL sites and ALL users • Met with broad agreement • If not used properly by the general user, the feature could in future be restricted to certain user groups (like the LHC VO shifters) SA1 face-to-face meeting - Abingdon 03/12/2008 - Torsten Antoni

  14. Effects on TPM • direct ticket routing frees some resources within the TPM effort • these will be used for: • aim at ticket assignment within one hour • TPM having now more time to dedicate to quality of support rather than assignment • First line support, focussed on debugging middleware issues • Monitoring of tickets • TPM being the second step in escalation for a ticket (SU, SU+TPM, SU+TPM+USAG) • Preparing the escalation reports • Further invitation, especially now that teams are beginning to use and contribute to the TPM wiki pages • Revising and contributing to the documentation SA1 face-to-face meeting - Abingdon 03/12/2008 - Torsten Antoni

  15. Plans, options & concerns • Plans • GOCDB interface / Direct routing (with GOCDB team) • Prototype Jan-2009 • Final Jun-2009 • Messaging as communication platform (with OAT) • Evaluation Mar-2009 • Standard defined Oct-2009 • VOMS interface (with VOMS team) May-2009 • Define and document new TPM role Apr-2009 SA1 face-to-face meeting - Abingdon 03/12/2008 - Torsten Antoni

  16. Plans, options & concerns • Options • Ticket distribution by origin of submitter • identify submitters’ region from DN • automatically assign ticket to ROC • TPM workload reduced further • Messaging for new interface or change also of old interfaces? • Move to the standard • TPM training for new role? • Yes • Concerns • Vagueness of EGI plans • Increase in interfaces • could be dealt with by strictly sticking to standard interface • promote federation of NGIs SA1 face-to-face meeting - Abingdon 03/12/2008 - Torsten Antoni

Get and stay involved • USAG meeting • Monthly meetings usually on the last Thursday of the month • Participation from OCC,ROCs, VOs, … https://twiki.cern.ch/twiki/bin/view/EGEE/SA1_USAG • ‘Shopping list’ meeting • Sub-group of USAG • Weekly meeting to prioritise requests and define content of releases https://savannah.cern.ch/projects/esc/ WLCG Data Taking Readiness WS - CERN 13/11/2008 - Torsten Antoni
