[monitoring-users] Monitoring a host in the network

[Dwijadas Dey]

Hi
      List users
                     I have installed naemon/thruk in CentOS 7. Now i
want to monitor few host and services.

Is it possible to clone /etc/naemon/conf.d/localhost.cfg manually and
change the host_name pointing to IP of a host in my network - like

define service {
  service_description            Swap Usage
  host_name                        IP address of system to be monitored
  use                                   local-service            ;
Name of service template to use
  check_command               check_local_swap!20!10
}

Once i manually created a config for a system in a network, Whether
thruk will reload the new settings automatically so that the
monitoring information like disk usage loads in the web interface?

For accomplishing above, shall i need to install anything in the host
to be monitored pointed by host_name ?

Thanks
