Recommended Alarms You Should Define

At a minimum, define alarms for node failure, CPU usage percentage (for domain average across all hosts and/or, as shown below, for each host), and memory usage :

$ nuodbmgr --broker ... --command "show alarmDefinitions" 

Alarm Definitions (3): 
  Alarm Definition [NodeFailed]: type=NodeFailed dimension=Host entity=* (Warning)
  Alarm Definition [cpu-watch]: type=StatAlert dimension=Host entity=* 
     metric=OS-cpuTotalTimePercent(None) GT 60.00 600s (Warning, Reset) 
  Alarm Definition [mem-watch]: type=StatAlert dimension=Host entity=* 
     metric=OS-memUsedPercent(None) GT 80.00 60s (Warning, Reset)
