Introduction

SAM monitoring – Current Situation

  • ~36 distributed OPS tests submission instances:
  • 4 HEP tests submission instances at CERN
introduction1
Introduction

SAM monitoring - Current Situation

  • OPS: CEs (ARC, CREAM, OSG), SRMv2, Site-BDII
  • HEP VOs: CEs (ARC, CREAM, OSG), SRMv2
    • ALICE: CREAM-CE
    • ATLAS: CREAM-CE, OSG-CE, OSG-SRMv2, SRMv2
    • CMS: ARC-CE, CREAM-CE, OSG-CE, OSG-SRMv2, SRMv2
    • LHCb: CE, CREAM-CE, SRMv2
introduction2
Introduction
  • Generating 8 monthly availability/reliability reports
    • Tier0/1s History (last 6 months, OPS VO)
    • Tier0/1s VO OPS (last 6 months, OPS VO)
    • 4 Tier0/1s HEP VOs (last 6 months, HEP VOs)
    • Tier0/1s Summary (last month, OPS+HEP VOs)
    • Tier2s (last month, OPS VO)
  • Proposal to remove OPS tests from reports
motivation
Motivation
  • OPS infrastructure part of EGI-InSPIRE
    • Not sure how it will be after end of project
  • OPS tests do not reflect how sites are doing for experiments
  • Maintenance of OPS tests not clear after EMI
  • Reduce effort in availability re-computations
  • Homogenize and reduce number of monthly reports
proposal
Proposal
  • Remove OPS numbers from all reports
  • Replace existing reports with:
    • One summary report per VO including T0/T1s/T2s
    • One history report per VO including T0/T1s
  • Having similar content to existing ones
impact
Impact
  • Funding agencies and RRB bodies will have more than one monthly number per Site
  • In case of test failure, site admins should be notified and be able to understand what the problem is based on the test output
adoption plan
Adoption Plan
  • Generate new reports for evaluation (March)
  • Review how T2s are evaluated compared to official OPS report (March/April)
    • Test may need changes (more verbose)?
    • Follow up on open issues
  • Present results and re-iterate process until confident with new reports (2/3 months)
  • Decide when to switch to new reports
