Edit templates

define host {

action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_
register 0
}

define service {

edit an example host

the host-pnp is the host directive, the srv-pnp is the service directive.

define host{
use linux-server,host-pnp}

define service {
use linux-server,srv-pnp
}

restart services:

systemctl restart npcd
systemctl restart httpd
systemctl restart nagios

after 10 - 20 minutes host pnp will start showing results.
