Nagios Core - Unable to get process status

[raul.hernandez]

Hello,

I installed nagios core in a centos 7.8 server but I'm getting an "Unable to get process status" error message in the home page


The service is running and when I check the logs I don't see any errors


Can you tell me if there are other locations or tests I can do to troubleshoot this error?
SELinux is disabled btw

Thanks,

Hi,

Thanks for posting to the Nagios Community Forum. Just to double-check make sure it's set to (SELinux) disabled in the following file:

Code: Select all

/etc/sysconfig/selinux

Do you see any errors in the Apache log?

Code: Select all

tail /var/log/httpd/error_log

Lastly, what instructions did you follow to install Core?

The apache log shows this:

so, I checked suexec logs and found some issues with file permissions which I corrected and apparently there are no more errors there but I'm still getting the same message in the home page

I followed this guide: https://assets.nagios.com/downloads/nag ... entos7.pdf

Thanks for your help

Make sure that there are execute permissions for this file and the other .cgi files. It should look like:

I was able to fix the issue by changing the permissions to 755 in /usr/local/nagios/bin/ and /usr/local/nagios/sbin/
Thanks!

Awesome! We'll lock this one up.
