Nagios Support Forum

Hey everyone, first post. I've inherited Nagios at my new job, and have been picking it up at a pretty good pace! Up until now, that is.

I cannot, for the life of me, figure out how Nagios knows who to alert when a host goes down. For any service, I can very quickly see how Nagios determines who to contact, but for host checks, no clue. Can anyone fill me in?

Thanks in advance!

Hosts are handled the same as services in this case. Every host is assigned contacts and contact groups to notify. If you don't see that in your host definitions, check the templates that it uses (or the templates that those use).

Hey agriffin, thanks for the reply.

I actually figured this out, after hours of scouring our configs. Our configs are a little spaghetti-strung. We have a system that auto-creates host files for servers that we know about, and ties those hosts to a generic-host.cfg template.

Thanks again.

No problem, glad you got it figured out!
