Notification - not send out to any contact

ok -
i’ve already read other posts about similar probs (like Director Notifications.conf).

The ‘commands.conf’ is available to director: /etc/icinga2/conf.d/ contains api-users.conf and commands.conf only.

i’ve exchanged ‘hostalive’ for ‘ping4’ - since mostly i want to try to start simple (check host UP/Down and notify acc. …) - no change in the result.

After enabling ‘debug-mode’ (# icinga2 feature enable debuglog) the following is shown after ‘host-DOWN’ event:

So it looks like a timing-problem?!
