Issue: No alerting is triggered, although it is down : A little question, if anyone have any idee ...

Running OPM 11500 Server OPM: W2K12  Host 2008R2; DB: MSSQLEXPRESS local

Parameters good:

• The downtime is 48h, Alert delay is 10mn (Happened during businees hours at 6PM)
  
• There is a good notification profile
• There is many monitors with threshold , Disc/CPU/Mem; services
  

In the notification profile mailbox , nothing came from this host:

But the clear trigger many mails (for each monitor), any ideas ?

  Many thanks !
