# Add this to any nagios service definition:

# (service_to_restart) could be any systemd service like httpd, apache2, sshd, postfix, etc.

# Here is a sample service definition:
define service {
use local-service

event_handler restart_script!postfix
}

# Note you will also need to add a sudo config like:
nagios ALL=(root) NOPASSWD: /bin/systemctl restart $service_to_restart
