Operations

• Sunday swing: CEN:BIP:L1RATE:AT:ZERO
  Either FCT master crate itself has a problem or Trigger display has a problem. When L1rate is exactly at 0, it can't be a real trigger problem.
• Saturday swing:

  [22:46] Dataflow trimmed level 3 node number 13, name: bfo-farm115 
       Received  reason 13 via node 3
  [22:46] Level 3 process crashed or aborted. Probable node trim 
       Daemon bfo-farm115 reported error state: SIGNALED
  [23:05] lost connection with FCT epics channels. Restarting FCT gateway didn't help
  

  It was a non-trigger-related network problem, fixed by Steffan & Matthias.

• To make sure DCH O2 level problem, we need to check OPR monitoring plots. L1 fast mon is not sensitive enough to show the effect. Need to check TSF weight=3, which is the most sensitive. wieght=2 wouldn't show the effect much either. Should pay attention to the absolute scale. Rahmat will check and report next week.
