Alerting based on multiple hosts - is it possible?

Hello,

Say I have 3 servers

Srv1 Srv2 Srv2

Is it possible to configure an alert so that it will fire only when the CPU test for all 3 servers has gone yellow or red? In other words, I don?t want Xymon to alert when one server or two servers are having problems. Only when all three are.

Thanks,

g
