No hosts show up

[chris1337c]

Let me rephrase what I did, I only "un-commented" out what I could see wasn't previously commented out (I didn't remove unncessary data comments) in the backup of the nagios.cfg I had prior to the update. So the one I just posted is a 1:1. I am not sure if data corruption caused this regardless, I may need some pointers correcting the errors.

I validated the host of the HV has no issue with the HD's.

Ya that would be a problem, lets find what file the other missing commands are in

Its super weird scott, basically every file with the correct settings has a ~ after it, and all of the files that are missing them don't. It's like it reverted but.... I just removed the ~ from the commands.cfg, and renamed the other one to commands.cfg.idk. and now here is the dump from the config:

That is strange, but it looks like you there now with just a warning for a notification interval less than its check interval on that one service.

[chris1337c]

There is a random winserver listed as a host and the text notifications stopped. I am digging into this now. I don't understand how this happened but I am happy 99% of it is functioning versus 0% currently.

[scottwilkerson]

I would look at the host detail page for this host and see if notifications show as

It ended up we had a contacts.cfg and contacts.cfg~ <<The ~ contacts had the original information> I renamed them, checked the notifications like you said and all is well! Thanks for the tips, the GREP commands helped me identify which files were wreaking havoc.

Great! Glad to hear it is all resolved!
