Failed to start LSB: NAGIOS SERVICE

[CapitanG]

Hi,
I added host to Nagios Core 4.3.4. Then I opened the web interface to see if I can see the HOST I added, but it is giving me error. When I click on Hosts on the left navigation pane I get the " Whoops! Error: Could not read host and service status information!" I tried to restart the Nagios service but it doesn't work. Nagios is loaded on Centos 7 OS. I am not familiar with LINUX so whatever I try I am doing it from what I read on the Internet. Please please help.

Can you post the output of the following

Code: Select all

systemctl status nagios

This is how the systemctl status looks like

Ok, this looks like you have a configuration error. You will need to verify your configuration

depending on file locations you would run something like this

Code: Select all

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