All, I recently discovered that my nagios setup is only storing in nagios_hostchecks table. In my ndomod.cfg file I have selected data_processing_options=67108863, which suppose to process all data. Little overview about my setup I have two mahcine running nagios active failover settings. On mysql side, I have master master replication from both machine. Can someone please advise me on this. I am including my nagios.cfg file, ndo2db.cfg file and ndomod.cfg file. Thanks in advance.
