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.

install

apt-get install python3-nagiosplugin python3-gi

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
