 Yes, but when it restarted, can't it see any data/graphs has been 
 update for hours ? What about updating rrd graphs with a 6h hole ?
 It turns purple when no data has been reported since 30min ? Xymon 
 turns itself to purple without having notification, doesn't it ?

 BTW : I'm already on UPS, but it ran out of power :-/
 Also, Hobbit starts after all other servers due to server-side 
 dependencies.
