  2. Which “More Tier0 Services” • ATLAS considers the Impactof twiki and email/e-groups service interruption high. Namely: • Twiki: • An incident produces “damage” in 2 hrs (Urgency: 7). • The whole VO is affected. Most ops services stop (Impact:10). • Email/E-groups: • An incident produces “damage” in 1 hr(Urgency: 8). • Some ops services stop (Impact:9). Source: 2012/03/20 WLCG MB Presentation (slides 8,9,10,15) with values confirmed by ATLAS Deputy Computing Coordinator on 2012/09/17. NB! Terms ‘Urgency’ & ‘Impact’ are NOT related to the expected response by the supporters. Maria Dimou - CERN / WLCG - TrackTools coordinator

  3. What ATLAS requires • The experts (3rd Line Support) to receive instant notification as soon as the ticket is created. • The experiment leaves at the experts’ discretion incident investigation OWH (Outside Working Hours). Maria Dimou - CERN / WLCG - TrackTools coordinator

  4. A workflow that works • GGUS ALARMs are automatically interfaced to SNOW by design and get to the experts with immediate email/phone notifications both from GGUS and email from SNOW. • So for critical services, where immediate attention is needed and justified, GGUS ALARM is the ticket type that the experiment should open. Maria Dimou - CERN / WLCG - TrackTools coordinator

  5. Background and Conclusions Maria Dimou - CERN / WLCG - TrackTools coordinator This is an action from the 2012/10/01 ATLAS-IT meeting. This proposal will be presented at the ATLAS-IT meeting of 2012/11/05. Before any technical action a management decision must be taken for new services’ addition into the ALARM workflow. Is the WLCG MB the right body? Comments/suggestions? Thank You for your attention!
