Speaker: Marco Roda (University of Liverpool)

Marco:

• OpMon Transition - link to status 
  • Almost every dashboard that has data is restored.
  • Missing: some changes in dfmodules, frontend, timing, trigger and HSI.  
  • New additions: we have a monitoring for the monitoring.
  • Issues:
    • The issues in trigger are already fixed (thanks Michal)
    • Similar naming issue in fdreadoutmodule. Unclear who is supposed to fix it, I might do it myself but feedback from experts is necessary.
  • No news from Timing
  • CRP developers should start using the new dashboard. 
  • Next step: start tackling the opmon configuration via OKS
     
• Today we had the same issue of multiple people using test session on the dashboard. The recipe provided by Gordon for renaming worked.
