All, I have two machines which are responsible for nagios monitoring. One is master and one is fail over. I am also keeping historical data in NdoUtils. I am using mysql for Ndoutils and they have master-master replication. So in master I have active check and active notification enabled. In fail over just the nagios process is running but there is no active check and active notification. Both have identical configurations. My question is Host A (master) is running NdoUtils and Host B (failover) is also running NdoUtils. Although I have master-master replication, but is there any possibility of proper copying of data from master to failover database? Please advise on this. Thanks -- Cordially, Shadhin Rahman
