  REFERENCE LINK: https://ggus.eu/index.php?mode=ticket_info&ticket_id=144342
  SUBJECT: NGI_CH - November 2019 - RP/RC OLA performance
  
  

  such tickets are a “standard formulation”, we have received tons in the past, affecting all sites, due to the fact that the ops probes failures go inevitably undetected, when these do not affect the production experiments. In this specific case, it is the first time the ticket has been also notified to the site. In the past, it was just assigned to the NGI_CH, so only I would receive notification. Then would do some investigation with the site, and report on the ticket. In some cases, Dario and Dino might remember, we never found the cause of some errors that appeared and went away on their own.

  F or this specific ticket, I had spotted the error (by pure chance) and reported to dario, it was corrected within <24h on the 22nd Nov.In fact, it can be seen in this link that the availability goes back to 100% by the end of that day https://egi.ui.argo.grnet.gr/egi/report-ar-group/Critical/2019-11/SITES/CSCS-LCG2

  
  I also see during that perios issues affecting the ARC CEs, but these went away spontaneously and it is no longer easy to investigate what happened back at failure times.
  
  To mitigate in the future, we have mentioned in the past that there exist the possibility of turning on notification at the site/service level in GOCDB. These will trigegr email to the GOCDB site contact in case some ops probes fail. Each site should choose their own matrix of notifications. There are two independent levels: site level (can be turned on by editing the main site page), and service level (can be turned on by editing each servic page)
