Go to

/etc/puppetlabs/code/modules/nagios/manifests

In the config.pp file copy and paste this block of code so there is a Nagios host to monitor each server

nagios_host { 'apps-a': <Edit here so there is one block each for 'apps' 'backup' and 'mgmt'
target => '/etc/nagios4/conf.d/ppt_hosts.cfg',
alias => 'apps', _< Edit here too _
check_period => '24x7',
max_check_attempts => 3,
check_command => 'check-host-alive',
notification_interval => 30,
notification_period => '24x7',
notification_options => 'd,u,r',
