• • ANALY_CSCS-HPC: 90%
  • CSCS-LCG2-HPC_MCORE: 85.5%
  • UNIBE-* : > 95%
    
    
• Running slots
  • Large number of stuck jobs on ARC skew the statistics for CSCS, creating reporting problems to ATLAS
  • Very likely due to the reported issues with the Daint scratch file system, affecting WLCG jobs in some way
    
    
  • This required a manual clean up:
    • job list provided by ATLAS, culled from the aCT
    • manual cleanup of the ARC sessiondir carried out by Miguel
  • 
    
    
    
    
• Accounting Numbers from the ATLAS dashboard (February 2019) CSCS+UNIBE
  

• Take home lessons from the last month:
  • Failed WC very high, we need some more real time alerts
  • Public dashboard replica offline: prevents monitoring on my/our side
  • ATLAS now relies fully on ARC services:
    • we need ARC metrics and/or logs available to ATLAS
    • we need monitoring/(nagios?) automated checks on ARC services
    • or we risk incidents like the one that occurred in February
  • Please report general Daint issues that could affect WLCG jobs (SLACK-general or email) so that we can react if needed
