Nagios core plugin issue

Posted: Wed Jul 19, 2017 10:18 am

Hello,

I was able to setup nagios core 4 on centos 7.
My problem is with check_ping plugin, it cannot run, I get "no such file or directory"
Adding any host to check, I get "down" status.

I tried several things that I read on other users posts without success.

I tried "ls -la /usr/local/nagios/libexec" and the files are there.

Code: Select all

Are you able to run the plugin directly? What happens if you run /usr/local/nagios/libexec/check_ping? What is the output of file /usr/local/nagios/libexec/check_ping. Did you compile the plugins manually, install from a repo, or copy them from another machine?
