erstellung eines Application/API Token

Die Scripte können 1zu1 kopiert und eingefügt werden.
Bei der Ausarbeitung habe ich versucht, so nahe wie möglich an der Konfiguration für die Email-Benachrichtigung zu bleiben.
Grund: Man kann die Unterschiede zum Original besser sehen und weitere Notifications für andere Dienste (SMS, Pushbullet, Signal, Telegram, …) erstellen

Um nicht alles umständliche aus diesem Wiki kopieren zu müssen, stehen alle Scripte und Konfigurationsdateien in meinem Git-Repo unter:
https://git.dinven.de/Monitoring/icinga-plugins/src/branch/master/notification/pushover

/etc/icinga2/scripts/pushover-service-notifiaction.sh

# POST an HTTPS request to https://api.pushover.net/1/messages.json with the following parameters:
#	token (required) - your application's API token
#	user (required) - the user/group key (not e-mail address) of your user (or you), 
#		viewable when logged into our dashboard (often referred to as USER_KEY in our documentation and code examples)
#	message (required) - your message 
#
#    Some optional parameters may be included:
#	device - your user's device name to send the message directly to that device, 
#		rather than all of the user's devices (multiple devices may be separated by a comma)
#	title - your message's title, otherwise your app's name is used
#	url - a supplementary URL to show with your message
#	url_title - a title for your supplementary URL, otherwise just the URL is shown
#	priority - send as 
#		-2 to generate no notification/alert, 
#		-1 to always send as a quiet notification,
#		 0 (default) to send notification with sound, vibration and display(not in quiet hours) 
#		 1 to display as high-priority and bypass the user's quiet hours, or 
#		 2 to also require confirmation from the user
#			retry
#			expire
#	timestamp - a Unix timestamp of your message's date and time to display to the user, rather than the time your message is received by our API
#	sound - the name of one of the sounds supported by device clients to override the user's default sound choice 
#
# That's it. Make sure your application is friendly to our API servers and you're all set.
# For more information on each parameter, keep reading or jump to a section at the left.

Kurze Beschreibung:

device:
- Devices können einzeln angegeben werden ([ „device1“ , „device2“ ])
- Wenn keine Device gesetzt ist, wird die Benachrichtigung an alle Devices gesendet
Standard-Priority = 0
Wenn Priorität = 2, dann muss retry und expire gesetzt sein. Sollte nichts gesetzt sein, wird via Script retry auf 30 und expire auf 300 gesetzt
