I think what you want to do is create Host Groups[1] that group your 
servers however you want (By location, operating system, whatever). You 
can then create Aggregate checks[2] based on the host group and a common 
item that all the hosts in the group have. For example:

grpmax["Linux Servers", "system.cpu.load[,avg1]", last]

That will give you a single value: the maximum CPU load from all your 
servers.

Once you have an aggregate value from your host group you can then 
create a trigger on that value:

{hostname:aggregate_name.last()} > 5

The "hostname" can be any host in your host group (I think! I'm doing 
this from memory!) and "aggregate_name" is the name of the aggregate you 
created above.

Once you create the trigger it will activate if any host in the host 
group goes over a CPU load of 5.

Hope this helps!
