Status ROD

  • Any problematic tickets?
MPI-K is asking for help (GGUS Ticket 83822). Test for CREAM CEs are failing. Problem is not known. Job is done but 
without exit code 0. In consequence Nagios tries to restart job.

Uni Bonn is suspended, seems to had the similar problem, but it was the wrong setup of the infosystem.
Is there a problem to mask alarms? We have many tickets to the same problem. Conclusion: Tickets were not handled in the 
right way. More comfortable is to mask the alarm.
1.number: alarms over 72 hours
2.number: ticket closed, experation date expired
