0	default Plugins on Debian	# /usr/lib/nagios/plugins	--> source
	define a new path for not default or modified Plugins	# mkdir /usr/lib/nagios/pluginsCustom
	define the new Path to ...	# vi /etc/icinga2/constants.conf	const PluginCustomDir = "/usr/lib/nagios/pluginsCustom"
	restart	# systemctl restart icinga2 # systemctl status icinga2
