Nagios Support Forum

I am LINUX beginer on nagios, I have this problem: (nagios core on Centos 7).
I fallow step by step this tutorial : https://www.unixmen.com/install-configu ... -centos-7/

Then when i access to the nagios administrative console and click on hosts,
my localhost is down and , I have this message:
(No output on stdout) stderr: execvp(/usr/local/nagios/libexec/check_ping, ...) failed. errno is 2: No such file or directory

Two days i am searching the web to fix my issue but i have found nothing to help me.

I need help thank you for your support.

It looks like you did not compile plugins. Take a look at that guide, under the section which says 'Install Nagios plugins' and that should get it fixed.

If not, please run ls -al /usr/local/nagios/libexec/ and show us the result.
