You can do this via a combo test defined in combo.cfg

https://xymon.sourceforge.io/xymon/help/manpages/man5/combo.cfg.5.html

i.e. you could define something like..

servers.cpu = (srv1.cpu + srv2.cpu + srv3.cpu) > 1

or perhaps...

servers.cpu = (srv1.cpu || srv2.cpu || srv3.cpu)

which would be green if one or more of the individual cpu tests were 
green. You could then alert on "HOST=servers TEST=cpu" as normal.
