monitoring Proxmox from Icinga

Hi all

I found this guide

http://pve.proxmox.com/wiki/Monitoring_with_Icinga

But my Icinga is installed on a Ubuntu 12.04 64 bit openVZ vm..

My Icinga installation is up and running and installed from this guide:
http://askubuntu.com/questions/16903...or-remote-host

also icinga-web is up and running.

I will asume the proxmox guide still applies even though i used ubuntu as os.. but where in the guide should i start when I have my Icinga up and running?

Does the proxmox guide still apply to the newst version of Proxmox?

THANKS

Casper
