Nagios Support Forum

The best way that I have seen to auto register a server is to drop a valid configuration into the import directory & run nagios_reconfigure.sh. Is this the correct way to do it or is there a better way to do this possibly through an api or any other automated fashion? Any help is appreciated.

If you need to scan for new hosts, you could just run the Auto-Discovery Wizard in Nagios XI. If your goal is to manage hosts/services from the CLI, you could following the steps, outlined in our "Automated Host Management" document.

This this is not what you want to do, could you please, explain in more details? I am not sure what" nrpe" has to do with the host management in XI...

Thanks for the response, the particular situation we're trying to solve is ephemeral hosts coming up on a software defined network that can reach the nagios server but the nagios server cannot reach, which means that auto discovery, unless we can have a satellite node inside of the software defined network that can proxy connections back to the main server, will not work for us.

The hack that we've done is to setup a small web service that sits on the nagios host, which creates a .cfg file, puts it into the import directory and runs the reconfigure_nagios. This causes a nagios restart (something that I was hoping to avoid) and as we can't determine when these hosts are going to register or delete themselves we're looking for a 100% end to end automated way to do this. I'm not sure if that's any clearer or not but that is our goal.

You're in a pretty tricky situation with this one, but most of it should be possible. The web server and reconfigure is not a bad way to go, but as you found is less than ideal with the restarting of core. You might try issuing a reload instead. It should repoll your configs and keep monitoring. Otherwise have you considered using passive checks or something like snmp traps and nsti?

Thanks we're working now with NSCA and are attempting NRDS now

Well, let us know if you have questions/run into issues with them!
