Change The Hostname In Url Sent In Alerts?

Hello!

 

When I get the alerts from up.time they may look as follows:


Notification type: Problem 19/Jun/2013 14:32

Host: srvsusepwtest01.malmo.se (OK)
Service: PW-Test-Access-Point
Service State: CRIT

Output: Socket error has occurred connecting to minasidor.test.malmo.se:443: Connection refused: connect

URL: SRVLNXQUEST01:9999/main.php

I have a real alias for the monitoring station that I would like to use instead of the hostname that is used in the alert URL. How can I change this?
