bernard- each ganglia machine sends out a periodic heartbeat message telling the group "i'm here". if the heartbeat messages stop for a particular machine, then the other hosts mark it as dead. if ganglia simply stopped reporting information about it then you would never know one of your hosts crashed and needs to be repaired.
