I have successfully installed the Nagio Core on Ubuntu Server 16.04 today.
I usually log in to Nagios Core and it says it's working normally, but when I add a new host by adding a .cfg file to "/usr/local/nagios/etc/servers", I restart Nagios service with the command

Code: Select all

$ sudo service nagios restart

, it returns me the message "Unable to get process status".

How do I add a new host?

Please share the output of the following command executed from the CLI of your Nagios Core machine:

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

From this page for additional explanation of what the command does:

It might also be handy to know what documentation/process you followed to install Nagios Core.

@chamados, We need to see whether there's a definition error in your config files or if that's an issue with the core installation itself. Please post the output of the command that @mcapra mentioned.
Also, please make sure that SELinux is disabled on your system.
