Nagios web interface isn't using the configuration files

Question

I want put my own configuration in the Nagios Core 4.3.4.

I have the following setting in Nagios:

/usr/local/nagios/etc/nagios.cfg

cfg_file=/usr/local/nagios/etc/objects/newhost.cfg
cfg_dir=/usr/local/nagios/etc/servers

/usr/local/nagios/etc/servers/ubuntu_host.cfg

define host {
    use                          linux-server
    host_name                    ubuntu_host
    alias                        Ubuntu Host
    address                      192.168.1.10
    register                     1
}

/usr/local/nagios/etc/objects/newhost.cfg

# Define a host for the local machine
define host{
    use                     linux-server
    host_name               google.com
    alias                   google.com
    address                 www.google.com
}

# Define a service to "ping" the local machine
define service{
    use                     generic-service
    host_name               google.com
    service_description     PING
    check_command           check_ping!100.0,20%!500.0,60%
}

define service{
    use                     generic-service
    host_name               google.com
    service_description     HTTP
    check_command           check_http
    notifications_enabled   0
}

The configuration validation is OK and it display 3 hosts:

Running pre-flight check on configuration data...
Checking objects...
    Checked 7 services.
    Checked 3 hosts.
    Checked 0 host groups.
    Checked 0 service groups.

    Checked 1 contact groups.
    Checked 24 commands.
    Checked 5 time periods.

    Checked 0 service escalations.

Checking obsessive compulsive processor commands...
Checking misc settings...
Total Warnings: 0
Total Errors:   0

I restarted nrpe service, nargios service and httpd service.

But Nargios Web Interface display the same information.

I have stopped all services. I have only started httpd service and nagios web interface display "Daemon running with PID 2097" but this PID not exist in the machine. — Frodogus, Jan 16 '18 at 16:21

I know this is late but I just encountered this today. but it seems after doing a few git push and git pull my chmod for /usr/local/nagios/var/objects.cache was changed to root instead of nagios.

I used ls -al /usr/local/nagios/var to check the timestamps and noticed this.

The solution for me was:

cd /usr/local/nagios/var/

chown nagios:nagios objects.cache

systemctl restart nagios

systemctl restart httpd

I got reference from https://support.nagios.com/forum/viewtopic.php?f=7&t=52727&p=276428&hilit=objects.cache+and+retention.dat#p276428
