#!/usr/bin/perl

use LWP::UserAgent;

LWP::UserAgent->new()->post(
 "https://api.pushover.net/1/messages.json", [
 "token" => "aizowaTOKENpcg5fdthz",
 "user" => "u6obubUSERkdjtcveq",
 "message" => $ENV{'message'},

 ]);

Create the text template which is sent to your device:

vim /etc/icinga2/zones.d/master/commands/pushover.conf

object NotificationCommand "push-notification" {
 import "plugin-notification-command"

 command = [ SysconfDir + "/icinga2/scripts/pushover.pl" ]

 env = {
 title = "$service.display_name$ on $host.display_name$: Status changed to $service.state$"
 message = "$service.output$"
 }
}

Add the notification template

vim /etc/icinga2/zones.d/master/templates.conf

template Host "notification-enabled" {
 vars.notification_enabled = true
}

template Service "notification-enabled" {
 vars.notification_enabled = true
}

Add the notification to the specific services you configured ( import )

vim /etc/icinga2/zones.d/master/services/ssh.conf

apply Service "ssh" {
        import "notification-enabled"
        import "5minute-service"

        check_command = "ssh"

        assign where host.vars.os == "Linux"
}

Add the apply notification template for the services and hosts

vim /etc/icinga2/zones.d/master/notifications.conf

apply Notification "push-notification" to Host {
  users = [ "mattionline" ]
  command = "push-notification"

  types = [ Problem, Recovery, Acknowledgement ]
  states = [ Critical, Warning, Unknown ]

  interval = 0
  assign where host.vars.notification_enabled == true
}

apply Notification "push-notification" to Service {
  users = [ "mattionline" ]
  command = "push-notification"

  types = [ Problem, Recovery, Acknowledgement ]
  states = [ Critical, Warning, Unknown ]

  interval = 0
  assign where service.vars.notification_enabled == true
}

Add the notification user

vim /etc/icinga2/zones.d/master/users.conf

object User "mattionline" {
  import "generic-user"

  display_name = "mattionline"

  email = "info@mattionline.de"
}
