With the Thomas Krenn Call-Home-Service a notification is automatically sent from your network monitoring system to the support team at Thomas Krenn regarding your hardware problems. After the hardware problem has been received by our support team, they will contact you immediately (Mon-Fri 7am - 10.30pm) to arrange a time to replace the faulty component. The days in which failed fans or power supplies going, for long periods of time, unnoticed and then later ultimately leading to the failure of your entire system are over!
Thomas Krenn Call-Home-Support is available starting July 23, 2013.
In order to use the Call-Home-Service, the following requirements must be met:
- Operation of one of the following network monitoring systems with network access to the server to be monitored:
- Operation of one or more Thomas Krenn servers that you want to monitor. The Call-Home-Service must be purchased for the monitored server during your order. For previously purchased servers the Call-Home-Service can be purchased as a service upgrade.

Configuration Call-Home Auth-Key
In order to use the Call-Home-Service, you need to enter your Call-Home Auth-Key in TKmon or in your Icinga or Nagios System.
Your Auth-Key can be found under "My account" at Thomas-Krenn:
