7 Monitoring, logging & reporting - the proposal

How we run the challenge on an hourly/daily/weekly basis... (i.e. from an "operational" point of view)

N.B. "If it ain't broken it probably hasn't been tested yet" -- Ian Fisk

12:30 lunch break

8 SRM v2.2 production status - sites

Review:

1. Has site upgraded to SRM v2.2 in production? (Y|N)
2. Has space management been turned on? (Y|N)
3. Are endpoints correctly published? (Y|N)
4. Are spaces correctly configured per token & VO? (Y|N)

9 SRM v2.2 production status - experiments

Review:

1. Experiment DM framework SRM v2.2 ready? (Y|N)
2. Tested client tools against production endpoints? (Y|N)
3. Tested FTS transfers against production endpoints? (Y|N)

14:30 coffee break

10 Tape statistics - proposal of what should be measured by Tier1s in February

Slides TapeCCRC08Metrics.pdf TapeCCRC08Metrics.pptx

11 The Metric

• How do we measure and report our "success", in terms of reporting upwards to: experiments, MB/OB, LHCC referees, CSO?
• What is the process for discussing and agreeing possible de-scoping?
• How do we discuss and agree possible stop-gap scenarios?
• Discussion and prioritisation of remedial actions?
• ...
• Is this purely a computing exercise or do we include (in May?) a physics component to the metric?

12 Daily WLCG Service Coordination meetings

Daily WLCG Service Coordination meetings – 15:00??? – Start 21st January 2008 latest?

(Longer on Mondays  operations & Thursdays  C5)

• WLCG Service Coordinator report & outlook
• “EIS” reports
• WLCG operations reports (summary from morning meeting or key services based on “critical services” lists?; monitoring / dashboard reports?)
• LHC news (when running…)
