+Whats this?
+===========
+This script is intended for icinga/nagios/icinga2 to check the state of a
+systemd service. We check the ServiceState and the Substate.
+
+optional features (future)
+--------------------------
+It is thinkable to check for every systemd service property.
+
+example code
+------------
+
+from gi.repository import GLib, Gio
+
+systemd = Gio.DBusProxy.new_for_bus_sync(Gio.BusType.SYSTEM, 0, None,  'org.freedesktop.systemd1',  '/org/freedesktop/systemd1',  'org.freedesktop.systemd1.Manager', None)
+
+apache2 = Gio.DBusProxy.new_for_bus_sync(Gio.BusType.SYSTEM, 0, None,  'org.freedesktop.systemd1',  systemd.LoadUnit('(s)', 'apache2.service'),  'org.freedesktop.systemd1.Unit', None)
+
+apache2.get_cached_property('ActiveState').unpack()
+-> 'active'
+ apache2.get_cached_property('SubState').unpack()
+ -> 'running'
+
+ apache2.get_cached_property_names()
+ -> Liste all systemd-properties
