Hi,
I’ve now formatted your post with markdown code blocks, please check Create topics and master Markdown formatting for future posts by yourself.
The configuration objects, especially the notifications, do not reference a period attribute which would explain the used timeperiod filter when it comes to notifications.
Please show the complete output of icinga2 object list --type Notification --name 'benecenvd10! Disk! NotificationService'.
Cheers,
Michael
