get all properties from a service from systemd using dbus (like "systemctl status $service")

get_service.py

import sys
import dbus

d = dbus.SystemBus()

systemd = d.get_object('org.freedesktop.systemd1','/org/freedesktop/systemd1')
manager = dbus.Interface(systemd, 'org.freedesktop.systemd1.Manager')

unit_proxy = dbus.Interface(service_proxy, 'org.freedesktop.systemd1.Unit',)
properties_interface = dbus.Interface(service_proxy, 'org.freedesktop.DBus.Properties')

all_properties = properties_interface.GetAll(unit_proxy.dbus_interface)

for k, v in all_properties.items():
    print k, v
