Can help
This prompt up everytime I've tried to 'Apply Configuration' after register new host or network devices.
I've go through the following kb or documentation from Nagios site but the issue still persist:
https://assets.nagios.com/downloads/nag ... tabase.pdf
https://support.nagios.com/kb/article.php?id=24
My last option is to ./reconfigure_nagios.sh base on this kb from Nagios: https://support.nagios.com/kb/article.php?id=532 but concern on the existing configuration will gone.
Thanks.
