  1. Availability Reports based on Nagios James Casey, David Collados

  2. Recap of March reports • March Availability reports for WLCG • Official SAM reports: http://gvdev.cern.ch/GRIDVIEW/downloads/Reports/201003/ • Unofficial Nagios report: http://gvdev.cern.ch/GRIDVIEW/downloads/Reports/201003-nagios/ • 171 Sites in the report • Sites whose availability increased in Nagios ≥ 10% 8 = 4.7% • Sites whose availability decreased in Nagios ≥ 10% 16 = 9.4% • Sites whose availability changed in Nagios ≥ 10% 24 = 14.0%

  3. April – WLCG reports • March Availability reports for WLCG • Official SAM reports: http://gvdev.cern.ch/GRIDVIEW/downloads/Reports/201004/wlcg/ • Unofficial Nagios report: http://gvdev.cern.ch/GRIDVIEW/downloads/Reports/201004-nagios/wlcg/ • 171 Sites in the report • Sites whose availability increased in Nagios ≥ 10% 5 = 2.9% • Sites whose availability decreased in Nagios ≥ 10% 3 = 1.8% • Sites whose availability changed in Nagios ≥ 10% 8 = 4.7%

  4. April – WLCG reports • Sites whose availability decreased in Nagios ≥ 10% 3 = 1.8% • VICTORIA-LCG2: fails org.gstat.SanityCheck • GSI-LCG2: lfc-mkdir fails on WN during org.sam.WN-Rep test • NO-NORGRID-T2: fails org.bdii.Entries test • Sites whose availability increased in Nagios ≥ 10% 5 = 2.9% • UNI-FREIBURG: lcg-cp connection times out in SAM srm-put test • Wuppertalprod: failed sBDII-performance test in SAM (now fixed) • T2_Estonia: fails ce-sft-lcg-rm-cr test in SAM • RRC-KI: fails ce-sft-lcg-rm test in SAM (SE not defined in BDII) • UKI-SOUTHGRID-BRIS-HEP: sBDII sanity test timeouts in SAM • All failures accounted to grid site problems

  5. April – WLCG reports • IT ROC evaluation on the availability based on SAM vs Nagios • Nagios availability higher due to different response to a failure: • In SAM each failure is accounted • Nagios has soft states and increases frequency of checks when there are failures • sBDII tests executed from ROC Nagios instances instead of GStat in Taiwan

  6. May Reports - Summary • We consider the Nagios infrastructure ready to replace SAM OPS submissions • Propose: generate official OPS reports for May based on Nagios • While we keep on running SAM OPS tests during May • Propose: stop SAM OPS submissions on 15th June after computation and validation of May reports
