E-Mail Benachrichtigung einrichten

  • Die meisten Dinge wurden hier schon durch das Icinga2-Team angelegt
  • Es werden daher auch keine Plugins, Command- und Notification-Definitionen mehr benötigt
  • Lediglich die E-Mail-Addresse an welche die Mails versandt werden sollen muss eingetragen werden

E-Mail-Addresse eintragen

  • vi /etc/icinga2/zones.d/global-templates/users.conf
/**
* The example user 'icingaadmin' and the example
* group 'icingaadmins'.
*/
object User "icingaadmin" {
import "generic-user"
display_name = "Icinga 2 Admin"
groups = [ "icingaadmins" ]
email = "tech@xinux.int"
}
object UserGroup "icingaadmins" {
display_name = "Icinga 2 Admin Group"
}

Mail-Benachrichtigung zu Host-Datei oder Template hinzufügen

  vars.notification["mail"] = {
   groups = [ "icingaadmins" ]
 }

Benachrichtigungs-Intervalle einrichten

  • times.begin setzt hierbei eine Wartezeit bis die erste Benachrichtigung versandt wird
  • interval setzt die Zeiträume zwischen den Benachrichtigungsversuchen fest
  • falls das versenden von Nachrichten nach einem bestimmten Zeitraum enden soll kann auch noch ein times.end gesetzt werden
template Notification "mail-service-notification" {
  command = "mail-service-notification"

  states = [ OK, Warning, Critical, Unknown ]
  types = [ Problem, Acknowledgement, Recovery, Custom,
            FlappingStart, FlappingEnd,
            DowntimeStart, DowntimeEnd, DowntimeRemoved ]

  interval = 15m
  times.begin = 30m

  vars += {
    // notification_icingaweb2url = "https://www.example.com/icingaweb2"
    // notification_from = "Icinga 2 Service Monitoring <icinga@example.com>"
    notification_logtosyslog = false
  }

  period = "24x7"
}

"message":{"message_id":353,"from":{"id":501616824,"is_bot":false,"first_name":"Herr","last_name":"Schmidt?","username":"Herr_Janning","language_code":"de"},"chat":{"id":-213374873,"first_name":"Herr","last_name":"Schmidt?","username":"Herr_Janning","type":"private"},"date":1511447683,"text":"Hallo"}}]}
