   3 # Alias: Monitoring core
   4 # Menu: Basic
   5 # Description:
   6 #  Here you can choose your monitoring core to run. Currently available
   7 #  are Nagios and Shinken. You also can decide to run no monitoring core in
   8 #  this instance. This can be useful for instances running a GUI such
   9 #  as Check_MK Multisite or Thruk which can connect to other monitoring
  10 #  sites via Livestatus.

  13 # target of the link exists
