[Xymon] Xymon on the Cloud

[Stephane Bakhos]

We have about 80 servers monitored by xymon and over 500 fake hosts (we 
have hostnames that specify some specific scripts that monitor our 
service).

The LA is near 0, about 3gb of ram used and 15 messages/sec  on average.

I've had a previous installation of xymon monitoring about 2000 servers 
and we never ran into scalability issues and I think the machine had 4 
cores / 8gb of ram on dedicated hardware.
