icinga2-rocketchat-notification

Your setup may vary, so some of the config files included here may need to be tweaked

• Set up a new incoming webhook /services/new/incoming-webhook for your team
• Add rocketchat-host-notification.sh and rocketchat-service-notification.sh to /etc/icinga2/scripts directory and make sure icinga can run them
• Add the contents of rocketchat-host-notification.conf and rocketchat-service-notification.conf to your conf.d/templates.conf (or keep it separate depending on your setup)
• Add the contents of rocketchat-host-notification-command.conf rocketchat-service-notification-command.conf to your conf.d/commands.conf (or keep it separate depending on your setup)
• Add an entry to your conf.d/notifications.conf (see example below)

apply Notification "rocketchat" to Host {
  import "rocketchat-host-notification"
  user_groups = [ "oncall" ]
  interval = 30m
  assign where host.vars.sla == "24x7"
}

apply Notification "rocketchat" to Service {
  import "rocketchat-service-notification"
  user_groups = [ "oncall" ]
  interval = 30m
  assign where host.vars.sla == "24x7"
}

• Set up a new user and usergroup if you didn't use a usergroup that already existed in you setup in the new conf.d/notifications.conf addition

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

  display_name = "oncall alerts"
  groups = [ "oncall" ]
  states = [ OK, Warning, Critical, Up, Down ]
  types = [ Problem, Recovery ]

  email = "my@email.com"
}

object UserGroup "oncall" {
  display_name = "oncall"
}

Sample message

The notification will look something like that (feel to imagine that you see an emoji instead of text when relevant):

:emoji: NOTIFICATION_TYPE HOST_NAME: STATE | HOST_OUTPUT | [ *COMMENT AUTHOR* ] COMMENT

:emoji: NOTIFICATION_TYPE HOST_NAME (SERVICE_NAME): STATE | SERVICE_OUTPUT | [ *COMMENT AUTHOR* ] COMMENT
