[Xymon] alerting by OS type

CLASS=aix

The CLASS name comes from the Xymon client running on the host, if is 
uses the "central mode" way of sending in data (if you don't know, check 
if there is a "client data" link on the cpu-status - if there is, then 
is uses central mode).

If you have an old-style Xymon client, then you can manually define the 
class with a CLASS entry in hosts.cfg.

If you change the hostname in hosts.cfg, then Xymon cannot match the 
hostname sent by the client with the hostname in hosts.cfg, so data is 
discarded - you will then see the server being listed in the "Ghost 
clients" report. You can overcome this by putting a "CLIENT:fooserver" 
on the "fooserver" entry in hosts.cfg.
