 Hi,

   My Xymon server (running Hobbit 4.2.2) has been shut down during 6  hours. When the power came back, Xymon came back too. I've checked all  monitored equipment, everything was green during the past 6h. I was  expecting purple or white color because no data has been reported during  the time. Is that a bug or a setting I could adjust ?

   Thanks.
