Installed Nagios and localhost is down

[clab]

Hello,

I've tried a few fixes I found through articles online with no luck but i'm running into a problem with Nagios alerting that localhost is down, when in fact it is up and running nagios.

Running on:
CentOS 7
Nagios 4.1.1
Nagios Plugin 2.0.3

Nagios alert:
ocalhost

Any help would be greatly appreciated, thanks!

Was this a clean/minimal install of Cent OS 7?
Refer to https://assets.nagios.com/downloads/nag ... 1456514247

I've done all of those steps in that documentation already BUT it looks like I installed the wrong nagios-plugin version.

Went ahead and installed the correct one indicated in the document you shared, didn't seem resolved until I rebooted CentOS and we're looking great now!

Thank you for your help!
